Sell Apple Watch SE 3 in the UK: 40mm, 44mm & Trade-In Value (2026)

Sell Apple Watch SE 3 in the UK: 40mm, 44mm & Trade-In Value (2026)

Want to sell your Apple Watch SE 3 in the UK? Sell My iPhone is currently particularly interested in buying Apple Watch SE 3rd Generation smartwatches, including the 40mm and 44mm versions with GPS or GPS + Cellular.

Whether you've upgraded to a newer Apple Watch, switched to a different smartwatch or simply stopped wearing yours, it could still have resale value.

Introduced in September 2025, Apple Watch SE 3 brought several important improvements to Apple's more affordable smartwatch range. These include an Always-On display, the S10 chip, fast charging and 64GB storage.

That makes it a relatively recent smartwatch with plenty of practical life left for another owner.

But how much is your Apple Watch SE 3 worth in 2026? Does the 44mm model sell for more than the 40mm? Does Cellular connectivity affect its value? And where can you sell it without dealing with individual buyers?

This guide explains what affects the value of an Apple Watch SE 3, how to prepare it for sale and how to find out whether Sell My iPhone can make you an offer.

Sell your Apple Watch SE 3 — check your trade-in options

Quick answer: To sell an Apple Watch SE 3 in the UK, confirm whether you own the 40mm or 44mm version and whether it has GPS or GPS + Cellular. Check its screen, battery health, casing and functionality, then search for your exact model on Sell My iPhone. Depending on the listing, you may see a price or be asked to submit a custom quote request. Sell My iPhone is currently particularly interested in acquiring SE 3 devices.

How much is an Apple Watch SE 3 worth in 2026?

There is no single resale price for every Apple Watch SE 3.

A 44mm GPS + Cellular Watch in excellent condition may receive a different offer from a 40mm GPS version with scratches or reduced battery health.

The amount a buyer is willing to pay depends on the exact configuration and the condition of the device.

What affects Apple Watch SE 3 trade-in value?

A Watch that looks almost new can still have a problem affecting its value.

For example, it may have poor battery performance or remain linked to the previous owner's Apple Account.

Equally, a fully working Watch with a few ordinary cosmetic marks may still be attractive to a refurbished-device buyer.

The best way to find out what your SE 3 is worth is to check the current selling options for your exact device.

Where can I sell my Apple Watch SE 3 in the UK?

There are several options, including specialist trade-in companies, private marketplaces and manufacturer trade-in programmes.

The right choice depends on whether you prioritise convenience, control over the asking price or a particular type of payment.

Sell to a specialist smartwatch buyer

A specialist trade-in service allows you to submit the device's details directly to a business interested in purchasing used technology.

Sell My iPhone buys smartwatches as well as phones and tablets.

The company is currently particularly interested in Apple Watch SE 3 devices.

You can search for the correct model, select the requested specifications and describe its condition.

Some listings show a trade-in price, while selected products use a custom quote request.

When a custom quote is required, the team reviews your submission and decides whether it can make you a current offer.

Sell your Apple Watch SE 3 privately

You could also sell the Watch through a private marketplace.

This allows you to set an asking price, but you will usually need to:

Photograph the Watch.

Create a listing.

Respond to interested buyers.

Negotiate a price.

Arrange secure payment.

Package and dispatch the device.

Handle any disputes.

A private sale might achieve a different return, but an advertised asking price is not a guaranteed sale price.

Trade in through a manufacturer

Manufacturer trade-in schemes can be useful when purchasing a replacement device.

However, offers vary and some promotions are linked to another purchase.

If you've already upgraded and simply want to sell your SE 3, comparing a specialist buyer's offer can be worthwhile.

Can I sell my Apple Watch SE 3 40mm?

Yes. The 40mm Apple Watch SE 3 is one of the configurations Sell My iPhone wants to acquire.

The smaller version is relatively lightweight and has a compact design.

Apple offered it in:

40mm GPS

40mm GPS + Cellular

Both versions use an aluminium case and have 64GB capacity.

Is the 40mm Apple Watch SE 3 worth selling?

Potentially, yes.

A smaller smartwatch can appeal to people who prefer a compact case and lighter weight.

The 40mm SE 3 still offers the same core generation of hardware as the larger model, including the S10 processor and Always-On display.

If you no longer wear yours, check whether a buyer is interested rather than assuming a smaller Watch has little value.

Does the smaller case mean a lower trade-in price?

Not automatically.

Different case sizes can command different prices, but the outcome depends on the current market.

Condition and connectivity also matter.

A clean 40mm Cellular Watch may be assessed differently from a damaged 44mm GPS model.

Search for Apple Watch SE 3 40mm

Can I sell my Apple Watch SE 3 44mm?

Yes. Sell My iPhone is also particularly interested in the 44mm Apple Watch SE 3.

This is the larger of the two SE 3 sizes.

Like the 40mm version, it was available with GPS or GPS + Cellular connectivity.

Why might somebody want the 44mm version?

Some buyers prefer a larger display for:

Notifications.

Workout information.

Reading messages.

Viewing complications.

Everyday navigation.

Others prefer the smaller case.

Neither size is universally better.

The important thing when selling is to identify your exact model.

Is Apple Watch SE 3 44mm worth more than 40mm?

It may be, but a higher resale price is not guaranteed.

A Watch's condition can have a greater effect on its value than the difference between the two sizes.

Select the correct configuration and request a current offer rather than relying on assumptions about the original retail price.

Search for Apple Watch SE 3 44mm

Does GPS or Cellular affect Apple Watch SE 3 trade-in value?

Yes, it can.

Apple Watch SE 3 was sold in GPS and GPS + Cellular versions.

The distinction matters because Cellular models offer additional connectivity when used with a compatible mobile plan.

Apple Watch SE 3 GPS

The GPS model can use its connection to a nearby iPhone or supported Wi-Fi network for connected functions.

This may be sufficient for people who usually carry their iPhone.

Apple Watch SE 3 GPS + Cellular

The Cellular version can access supported mobile services without requiring the paired iPhone to be nearby.

This can be useful for people who want to go running, walk or exercise without carrying a phone.

The SE 3 Cellular model also supports newer mobile connectivity technology, subject to network availability and compatibility.

Does Cellular automatically mean a better offer?

No.

Some second-hand buyers specifically want Cellular connectivity.

Others have no intention of activating a mobile plan.

As a result, the resale premium can vary.

Always submit the correct GPS or GPS + Cellular version.

How do I identify my Apple Watch SE 3?

This is an important step because the Apple Watch SE generations look similar.

Apple released:

Apple Watch SE 1st Generation in 2020.

Apple Watch SE 2nd Generation in 2022.

Apple Watch SE 3rd Generation in 2025.

Do not assume you own the third generation simply because the Watch says SE.

Find the model number

On the iPhone paired with your Apple Watch:

Open the Watch app.

Select My Watch.

Tap General.

Open About.

Find Model Number.

Tap the number to reveal the identifier beginning with A.

For common UK and European SE 3 models, Apple lists:

Different regional model numbers also exist.

These identifiers help distinguish SE 3 from SE 2 and the original SE.

For complete details, use Apple's official Watch identification guide.

What colours does Apple Watch SE 3 come in?

Apple Watch SE 3 was released in two aluminium finishes:

Midnight

Starlight

Both are official colours.

Does colour affect the resale price?

Potentially, but there is no guaranteed premium.

Some buyers prefer darker watches, while others prefer lighter finishes.

Physical condition and functionality are usually more useful considerations than trying to predict which colour will be most popular.

Can I sell a Midnight Apple Watch SE 3?

Yes. Midnight is an official SE 3 finish and can be submitted for consideration.

Can I sell a Starlight Apple Watch SE 3?

Yes. Starlight is the other official SE 3 aluminium finish.

Check the Watch's condition and choose the appropriate model when requesting an offer.

Does Apple Watch SE 3 have different storage sizes?

No.

Apple Watch SE 3 has 64GB of internal storage.

There are not separate 32GB, 128GB or 256GB versions of the SE 3.

The main product differences are:

40mm or 44mm case.

GPS or GPS + Cellular.

Midnight or Starlight finish.

Those are the details worth checking before submitting a valuation request.

Is Apple Watch SE 3 still worth selling in 2026?

Yes. Apple Watch SE 3 remains a relatively recent smartwatch, introduced in September 2025.

Although newer Apple Watch models are available, the SE 3 offers several features that make it practical for another owner.

These include:

S10 processor.

Always-On Retina display.

64GB storage.

Heart-rate tracking.

Sleep tracking.

Wrist temperature sensing.

Fast charging.

Fall Detection and Crash Detection.

Apple Pay.

GPS and optional Cellular connectivity.

Apple rates the SE 3 for up to 18 hours of normal battery life under its testing conditions.

It also supports fast charging, with Apple advertising a charge from 0% to 80% in approximately 45 minutes under specified conditions.

These are useful features for a second-hand buyer.

Why does this matter when selling?

Not everyone needs an Apple Watch Ultra or the newest Series model.

Some buyers want a relatively modern Apple Watch that covers everyday health tracking, notifications, workouts and payments.

A used SE 3 may meet those needs.

That creates a reason for owners who have upgraded to check whether their old device can be sold.

Apple Watch SE 3 vs SE 2: What's different for resale?

The SE 3 introduced several improvements over SE 2.

This is relevant because people searching for an affordable second-hand Apple Watch may compare both generations.

Why is the Always-On display significant?

The SE 3 introduced an Always-On display to the SE range.

This means the Watch can show information without requiring the same wrist-raising interaction as older SE models.

For some buyers, that is a meaningful improvement.

Does newer hardware guarantee a higher trade-in value?

Not automatically.

Although SE 3 has newer hardware, the actual resale value still depends on condition, demand and the exact configuration.

A badly damaged SE 3 may not be worth more than every well-maintained older Watch.

However, the newer features help explain why SE 3 remains relevant in the used-smartwatch market.

Should I sell my Apple Watch SE 3 after upgrading?

If you have already replaced it, checking its resale value can make sense.

Perhaps you've upgraded to:

Apple Watch Series 11 or Series 12.

Apple Watch Ultra.

Another smartwatch brand.

Or maybe you've decided you don't need a smartwatch at all.

In each case, your SE 3 may now be unused.

Is it worth keeping as a backup?

Possibly.

A spare Watch can be useful if you genuinely switch between devices.

But consider whether that is likely to happen.

If you have already transferred everything to your replacement Watch and haven't worn the SE 3 since, keeping it indefinitely may not provide much value.

When is the best time to sell?

There is no guaranteed perfect day.

Used smartwatch prices change as new models arrive, second-hand supply increases and buyer demand changes.

If you already know you no longer need your SE 3, checking its current value is a sensible starting point.

Does Apple Watch SE 3 battery health affect resale value?

Yes.

Battery performance can influence how a used smartwatch is assessed.

All rechargeable batteries lose capacity with time and use.

A Watch with reduced battery capacity may need charging more frequently than when it was new.

How to check Apple Watch SE 3 battery health

On the Watch, open:

Settings → Battery → Battery Health

Look for Maximum Capacity.

This indicates the estimated remaining battery capacity relative to its original condition.

You should also consider how the Watch behaves.

Does it:

Charge normally?

Last through your usual daily use?

Shut down unexpectedly?

Lose power unusually quickly?

Show a battery service warning?

If you know the battery has a problem, disclose it accurately.

What battery health does Sell My iPhone require?

Sell My iPhone's published grading terms distinguish battery condition between grades.

Its general Grade A criteria specify at least 90% battery health, while the standard working Grade B and Grade C descriptions specify at least 85%.

Battery performance below the relevant threshold may affect grading or require a revised offer.

Always check the current requirements for your particular Watch.

Should I replace the battery before selling?

Not automatically.

Battery replacement costs money.

A repair only makes financial sense if the additional value it creates justifies the expense.

Before paying for a replacement, check whether Sell My iPhone can consider the Watch in its current condition.

Can I sell an Apple Watch SE 3 with scratches?

Potentially.

Cosmetic wear is common on a smartwatch because it is worn on the wrist.

An SE 3 may acquire marks from everyday contact with desks, walls and other objects.

The important distinction is how significant the wear is.

Light casing scratches

Minor marks on the aluminium case are different from deep dents or structural damage.

Check the edges and the areas around the buttons.

Screen scratches

Apple Watch SE 3 uses Ion-X front glass.

Although Apple improved its crack resistance compared with the previous SE generation, the screen is not immune to damage.

Inspect it in good lighting.

Look at the display both switched on and off, as some marks are easier to see when it is dark.

Does a scratched Watch still work?

It may do.

However, a fully functional Watch with scratches is not necessarily graded the same as one in excellent cosmetic condition.

Choose the condition that accurately describes your device.

Can I sell an Apple Watch SE 3 with a cracked screen?

You can enquire, but acceptance depends on the damage.

A cracked screen can affect the Watch's appearance, usability and repair costs.

Check whether:

The display still turns on.

Touch input works.

There are black areas or coloured lines.

The casing has additional damage.

The Watch charges normally.

Do not assume the device has zero value.

However, do not describe a cracked screen as ordinary cosmetic wear.

If you're unsure whether Sell My iPhone can accept it, contact the team before sending it.

What should I test before selling my Apple Watch SE 3?

A short check can help you describe the Watch accurately.

Screen and touchscreen

Check the display for cracks, dead pixels and touch faults.

Digital Crown

Rotate and press the Digital Crown to make sure it responds.

Side button

Check that the button functions normally.

Charging

Connect the Watch to a compatible charger and confirm that it charges reliably.

Battery

Review Battery Health and note any abnormal behaviour.

Speaker and microphone

Test audio where possible.

Fitness and health sensors

If you know of an issue affecting heart-rate tracking or other supported sensors, disclose it.

Connectivity

Check Wi-Fi, Bluetooth and Cellular functionality where relevant.

You do not need specialist diagnostic equipment to perform a basic inspection.

The aim is to provide an honest description.

How do I remove Activation Lock from Apple Watch SE 3?

Removing Activation Lock is essential before selling an Apple Watch SE 3.

Activation Lock is designed to stop another person from activating a Watch still linked to its previous owner's Apple Account.

This protects against theft.

However, it must be removed when transferring ownership legitimately.

How to unpair Apple Watch SE 3

Keep your Watch and paired iPhone close together.

Then:

Open the Watch app on your iPhone.

Select My Watch.

Tap All Watches.

Tap the information button beside your SE 3.

Choose Unpair Apple Watch.

Confirm the action.

Remove the mobile plan if you're selling a Cellular model.

Enter your Apple Account password when requested.

Complete the unpairing process.

Apple explains that correctly unpairing through the paired iPhone erases the Watch and removes Activation Lock.

Is simply factory-resetting enough?

Not necessarily.

Erasing a Watch directly can leave Activation Lock enabled.

That means the next owner may be unable to set it up.

This is why Apple's recommended unpairing process matters.

Read Sell My iPhone's Apple Watch unpairing guide

You can also follow Apple's official instructions.

What if I no longer have the iPhone paired to my SE 3?

You may still be able to remove the Watch from your account.

Apple provides instructions for erasing devices and removing Activation Lock through Find Devices on iCloud.com.

Follow the official process carefully.

Do not send a Watch that remains locked to your Apple Account.

A buyer must be able to activate the device normally.

Apple's guide to removing a device from Find Devices

Do I need to cancel my Apple Watch SE 3 Cellular plan?

If your SE 3 has GPS + Cellular, check whether you still have an active mobile subscription for the Watch.

When unpairing it for sale, choose the appropriate option to remove the mobile plan.

You may also need to contact your network provider to cancel the subscription.

Removing the plan from the Watch does not necessarily cancel the billing agreement.

This is worth checking if you pay an additional monthly amount for smartwatch connectivity.

Do I need the Apple Watch SE 3 charger and strap?

Yes. Sell My iPhone's published preparation instructions say smartwatches should include their charger and strap.

This is an important distinction because ordinary phones and tablets may have different accessory requirements.

Charger

Locate the compatible Apple Watch charging cable.

If you no longer have it, ask the team for guidance before dispatch.

Strap

Include the required strap.

Make sure it is suitable for the Watch and follow any instructions associated with your agreed sale.

Original retail box

A missing retail box does not automatically mean a used Watch cannot be considered.

However, a Watch submitted as brand-new and factory-sealed has different grading requirements.

If the packaging has been opened, do not describe it as sealed.

Read Sell My iPhone's device preparation guide

Can I sell an unopened Apple Watch SE 3?

You can submit an unopened SE 3 for consideration.

However, condition descriptions need to be accurate.

There is a difference between:

Brand-new and factory-sealed

and:

Opened but never worn

Sell My iPhone's published grading criteria specify that a new-grade device must retain its original factory seal.

If your Watch has been opened, select the condition that actually applies.

This helps prevent unnecessary changes to a quoted price later.

How do I sell Apple Watch SE 3 to Sell My iPhone?

Sell My iPhone is currently particularly interested in acquiring Apple Watch SE 3rd Generation devices.

The process starts with finding the correct product.

Step 1: Search for Apple Watch SE 3

Visit the Sell My iPhone device catalogue.

Search for:

Apple Watch SE 3

or:

Apple Watch SE 3rd Generation

Step 2: Select the correct model

Check:

40mm or 44mm.

GPS or GPS + Cellular.

The exact product listing.

Do not select SE 2 or an older SE simply because it appears similar.

Step 3: Enter the requested information

Complete the device options shown on the listing.

This may include the network, specifications and condition.

Describe scratches or faults accurately.

Step 4: Follow the listing's offer process

Some products show an advertised trade-in price.

Selected products use a custom quote request instead.

If your SE 3 listing requests a custom quote, complete the information and follow the Submit and Check Out instructions.

Step 5: The team reviews the request

For custom quotes, the details reach the Sell My iPhone team.

The team can consider the device, its condition and the current market before deciding whether it can make an offer.

Submitting a custom quote request does not guarantee a price or mean the sale is complete.

Step 6: Proceed if an offer is agreed

If an offer is provided and you decide to proceed, follow the applicable instructions.

Properly unpair and erase the Watch before sending it.

Do not dispatch a device solely because you submitted an enquiry.

Search for your Apple Watch SE 3 and request an offer

What if I can't find Apple Watch SE 3 on the website?

First confirm the model name and try another search.

You can search for:

Apple Watch SE 3

Apple Watch SE 3rd Gen

Apple Watch SE (3rd generation)

If the exact device does not appear, do not select an incorrect model.

Sell My iPhone's FAQs explain that customers can contact the team if a product isn't listed, as it may still be able to make an offer.

You can email:

help@sellmyiphone.co.uk

Include the exact model, size, connectivity and condition.

What happens after Sell My iPhone receives my Watch?

After an agreed sale, Sell My iPhone inspects devices to confirm that they match the description.

For an Apple Watch SE 3, this can include checking:

Model and case size.

Screen condition.

Cosmetic wear.

Charging and controls.

Battery health.

Functionality.

Activation Lock status.

If the Watch differs from the condition originally described, a revised offer may be necessary.

Sell My iPhone's published terms explain how revised offers are handled.

Read the current terms carefully before completing a sale.

How long is an agreed quote valid?

Sell My iPhone's published terms generally provide a 14-day price guarantee for qualifying quoted devices received within the required period and matching the agreed condition.

This applies after a price has actually been quoted.

It does not mean every custom quote enquiry automatically receives an offer.

Read the current terms and conditions

How should I package Apple Watch SE 3 for posting?

Once an offer is agreed and you receive dispatch instructions, package the Watch carefully.

Photograph the condition

Take clear photographs showing:

Display.

Aluminium case.

Digital Crown.

Side button.

Back of the Watch.

Existing marks or damage.

Protect the screen

Use suitable padding and packaging.

Do not place the charging cable directly against the display where it could cause damage during transit.

Include the required accessories

Follow the smartwatch requirements for the charger and strap.

Keep proof of postage

Retain the receipt and tracking information.

For higher-value items, check whether the postage service provides sufficient compensation.

Follow Sell My iPhone's specific dispatch instructions for your agreed sale.

Should I sell Apple Watch SE 3 now or keep it?

There is no universal answer.

If you use the SE 3 every day and it does everything you need, keeping it may be the sensible decision.

It remains relatively recent hardware.

However, if you've already upgraded and your SE 3 is unused, checking its resale value can be worthwhile.

Why not leave it in a drawer?

Unused technology can lose value over time as newer devices arrive and the second-hand market changes.

Rechargeable batteries also age.

That does not mean every Watch loses value at the same rate.

However, keeping a device indefinitely does not guarantee its value will be preserved.

If you know you no longer need it, a current offer can help you decide what to do.

Why does Sell My iPhone want Apple Watch SE 3 devices?

Apple Watch SE 3 occupies a useful position in the refurbished-smartwatch market.

It offers many everyday Apple Watch features without requiring someone to buy a premium Ultra model.

A buyer may want:

A relatively modern Apple Watch.

A smaller 40mm case.

A larger 44mm display.

GPS + Cellular functionality.

An Always-On display.

Fast charging.

A more affordable alternative to a flagship Watch.

These use cases can create demand for well-maintained used SE 3 devices.

That's one reason Sell My iPhone is currently particularly interested in acquiring them.
