How Much Is My Apple Watch Worth in 2026? UK Trade-In Values by Model and Condition

How Much Is My Apple Watch Worth in 2026? UK Trade-In Values by Model and Condition

An old Apple Watch can still be worth anything from a relatively small amount to several hundred pounds in 2026. The exact value depends on the generation, case size, GPS or Cellular specification, physical condition, battery performance and whether the Watch is ready for another owner to use.

That means there is no single answer to “how much is my Apple Watch worth?”

A Series 6, Series 9 and Apple Watch Ultra may all still work perfectly well, but they sit in very different parts of the second-hand market.

As of 25 September 2026, Sell My iPhone's live site is showing example Apple Watch values ranging from £25 for a Series 6 40mm GPS to £330 for an Apple Watch Ultra 3 49mm GPS + Cellular. These are live examples rather than guaranteed prices: values change and the final amount depends on the exact model and condition.

Check your Apple Watch's current value

Quick answer: Find the exact Apple Watch generation, case size and GPS/Cellular configuration first. Then check the screen, casing, buttons, battery health and Activation Lock status. Newer Watches and Ultra models generally command higher values, but condition can make a significant difference.

Current Apple Watch trade-in values in the UK

Here are examples appearing on Sell My iPhone's live site when checked on 25 September 2026.

These figures are useful for understanding the market, but they are not a permanent Apple Watch price list.

Sell My iPhone says a quoted price is guaranteed for 14 days when the device arrives within that period and matches the grade and condition supplied. If the Watch differs from the description, the company may provide an updated quote.

So the best way to answer “what is my Apple Watch worth?” is to identify your exact Watch and check a live valuation.

Search your Apple Watch on Sell My iPhone

Why can two Apple Watches from the same Series have different values?

Because “Apple Watch Series 9” is not one single product.

Apple has sold many generations in different:

• case sizes;
• case materials;
• colours;
• GPS configurations;
• GPS + Cellular configurations.

For example, Apple Watch Series 9 was available in both 41mm and 45mm, with separate GPS and GPS + Cellular versions. Apple also sold aluminium, stainless-steel and Hermès configurations.

Consequently, simply knowing that you own a “Series 9” is not enough for an accurate valuation.

How do I find out which Apple Watch I have?

This is the first thing to do.

Apple provides an official identification guide covering everything from the original Apple Watch through current Series, SE and Ultra generations.

Use Apple's official Apple Watch identification guide

Find the model number

On the iPhone paired with the Watch:

1. Open the Apple Watch app.
2. Tap My Watch.
3. Open General.
4. Tap About.
5. Find Model Number.
6. Tap the number beginning with “M” to reveal the model number beginning with “A”.

Apple's identification page then lets you match that number to the exact model.

Check the back of the Watch

The back of an Apple Watch also carries useful information.

Depending on the generation, you may see details such as:

• case size;
• case material;
• GPS/Cellular information;
• Series or Ultra branding.

That can quickly tell you whether you have, for example, a 41mm or 45mm device.

Does Apple Watch size affect value?

It can.

The different case sizes are separate products.

Depending on generation, Apple has offered sizes including:

• 38mm;
• 40mm;
• 41mm;
• 42mm;
• 44mm;
• 45mm;
• 46mm;
• 49mm.

A Series 9 41mm and Series 9 45mm should therefore be valued as their exact variants rather than treated as identical.

The same applies when you are buying refurbished: compare the correct size rather than simply searching the Series number.

Is GPS + Cellular worth more than GPS?

Often, but not automatically by the same amount.

GPS + Cellular models contain mobile connectivity that can allow the Watch to access supported network services when away from the paired iPhone.

That makes them a different configuration from GPS-only Watches.

Current Sell My iPhone examples illustrate the distinction. Its homepage shows Series 6 40mm GPS at £25 and Series 6 40mm GPS + Cellular at £30 at the time of checking.

However, resale values are market-driven, so there is no permanent rule saying Cellular always adds a particular amount.

Does Apple Watch battery health affect resale value?

Battery condition can matter because it directly affects how useful the Watch is.

Apple Watch batteries are rechargeable components with a limited lifespan.

Apple allows you to check the remaining estimated capacity directly on the Watch:

Settings → Battery → Battery Health → Maximum Capacity

The percentage shown measures battery capacity relative to when the battery was new.

Apple's guide to Apple Watch battery health

100% charge does not mean 100% battery health

These are different measurements.

A Watch can display:

100% battery

because it has been fully charged.

Its Maximum Capacity might still be substantially below 100%.

That means it holds less energy than it did when new.

What battery health is good for selling an Apple Watch?

There is no universal percentage at which a Watch suddenly becomes sellable or unsellable.

However, stronger battery health generally makes a used Watch more attractive because the next owner should get longer runtime between charges.

If your battery drains unusually quickly, Apple recommends checking Battery Health and seeking service if the Watch reports that the battery needs service.

Should I replace the battery before selling?

Not automatically.

Treat this as a financial calculation.

Imagine a Watch is worth £70 in its current condition.

If battery service costs significantly more than the additional resale value you would gain afterwards, repairing it purely for sale would make little sense.

A better order is:

1. check the current value;
2. check the battery condition;
3. obtain any relevant service cost;
4. estimate the value after repair;
5. compare the difference.

Do not spend money repairing technology before you know whether the repair will pay for itself.

Does a scratched Apple Watch lose value?

Potentially, yes.

However, ordinary cosmetic wear and serious damage are very different.

Light cosmetic wear

Examples include:

• fine screen scratches;
• small case marks;
• slight wear around edges;
• normal strap wear.

A Watch can have these marks while remaining completely functional.

More significant damage

Examples include:

• cracked display;
• deep gouges;
• touchscreen faults;
• broken Digital Crown;
• damaged side button;
• charging problems;
• sensor faults.

These problems are more likely to affect condition grading significantly.

Sell My iPhone's site uses condition grades and says received devices are inspected against the condition supplied when the quote was created.

Can I sell an Apple Watch with a cracked screen?

Potentially.

Damage does not automatically mean an Apple Watch has zero value.

Sell My iPhone says it accepts both working and damaged devices and may even consider completely dead devices when repair and resale remain viable.

The economics depend heavily on the Watch.

A damaged recent Ultra may retain substantially more underlying value than a severely damaged much older Series model.

So check the damaged valuation before paying for a screen repair.

Check Sell My iPhone's current FAQs

Is an Apple Watch Series 6 still worth anything?

Yes, depending on the exact model and condition.

As of 25 September 2026, Sell My iPhone's homepage shows:

• Series 6 40mm GPS — £25
• Series 6 40mm GPS + Cellular — £30

as headline examples.

That is a useful reminder that an older Watch does not automatically become worthless.

£25 or £30 may not feel like a huge amount compared with the original retail price, but it is still more useful than leaving the Watch unused indefinitely if you know you will never wear it again.

How much is an Apple Watch Series 7 worth?

Sell My iPhone's current homepage shows examples including:

• Series 7 45mm GPS — £45
• Series 7 45mm GPS + Cellular — £50

at the time of checking.

Exact case size, connectivity and condition still matter.

Series 7 is now several generations old, so battery condition becomes increasingly relevant too.

How much is an Apple Watch Series 8 worth?

One current Sell My iPhone example is:

Apple Watch Series 8 41mm GPS + Cellular — £75.

Series 8 is also notable in 2026 because it falls outside Apple's current watchOS 27 compatibility list.

Apple says watchOS 27 supports Series 9 and later, SE 3 and Ultra 2 and later.

That does not make Series 8 unusable.

It does mean software support is becoming another factor for buyers comparing Series 8 with Series 9.

For more on that distinction, read our guide to Apple Watch Series 12, watchOS 27 and whether to sell an older Watch.

Is Apple Watch Series 9 still valuable?

Series 9 occupies an interesting position in 2026.

It is several generations behind the newest hardware, but Apple still includes Series 9 on the watchOS 27 compatibility list.

Sell My iPhone's current homepage shows Series 9 45mm GPS + Cellular at £100. It also displays a 41mm Cellular version at the same headline figure.

That software support can help Series 9 remain attractive in the refurbished market because somebody buying one is not immediately starting with a Watch excluded from Apple's current major OS.

How much is Apple Watch Series 10 worth?

One live Sell My iPhone example is:

Apple Watch Series 10 42mm GPS + Cellular — £125.

Series 10 is also still supported by watchOS 27.

Therefore, it can appeal to buyers who want relatively recent hardware without necessarily paying for the newest Watch generation.

That creates the two sides of the refurbished market:

• owners receive money for technology they no longer use;
• buyers can access capable previous-generation hardware for less.

Our broader guide to the best refurbished smartwatches to buy in 2026 explains how Apple Watch compares with Galaxy Watch and Garmin.

What about Apple Watch Series 11?

Series 11 is still comparatively recent.

Sell My iPhone's current homepage displays:

Apple Watch Series 11 46mm GPS — £150.

For an owner who has already upgraded again, that is significant enough that storing the old Watch unused deserves some thought.

The key question is not whether it might be useful one day.

It is whether you realistically expect to wear it again.

How much is Apple Watch Ultra 2 worth?

Ultra models sit in a different part of the market from standard Series Watches.

They originally target buyers seeking premium materials, a larger 49mm design and more outdoor-focused functionality.

Sell My iPhone currently displays:

Apple Watch Ultra 2 49mm GPS + Cellular — £230.

That is a substantial residual value for technology that could otherwise sit unused after an upgrade.

Ultra 2 also remains compatible with watchOS 27, which starts with Ultra 2 in the Ultra family.

How much is Apple Watch Ultra 3 worth?

Sell My iPhone's live homepage currently shows:

Apple Watch Ultra 3 49mm GPS + Cellular — £330.

Again, this is an example current figure rather than a fixed guarantee.

It does demonstrate why it is worth identifying premium smartwatches rather than assuming they are simply “old tech”.

Several hundred pounds can remain tied up in one small wearable device.

Does watchOS support affect Apple Watch value?

Potentially.

Software support is one factor in remaining useful life.

Apple currently says watchOS 27 supports:

• Apple Watch SE 3;
• Apple Watch Series 9 and later;
• Apple Watch Ultra 2 and later. 

That means models such as Series 8 and the original Ultra do not receive the newest major watchOS release.

Unsupported does not mean unusable

An older Watch can continue working with the software it already supports.

It may still provide:

• notifications;
• workouts;
• timers;
• activity tracking;
• music controls;
• other existing features.

However, a buyer comparing two similar Watches may be willing to pay more for one that remains inside Apple's current software-support window.

This is one reason Series 9 may hold a different second-hand position from Series 8 even where both Watches remain physically excellent.

What matters most: age or condition?

Both matter.

A newer Watch starts from a stronger underlying market position.

Condition then determines how attractive that particular example is.

Think of valuation as layers:

Model → specification → condition → battery → account status → current market demand

A pristine Series 6 does not automatically become worth more than a clean Series 10 simply because it has fewer scratches.

Likewise, a severely damaged Series 10 will not necessarily receive the same value as an excellent Series 10.

Does Activation Lock affect Apple Watch resale?

Yes — substantially.

Before selling an Apple Watch, Apple says you need to remove your personal information and turn off Activation Lock.

The easiest method when you still have the paired iPhone is to unpair the Watch through the Apple Watch app. Apple says this erases the Watch, restores it to factory settings and removes Activation Lock.

Apple's official guide to selling or trading an Apple Watch

Do not simply erase the Watch and assume you are finished

This distinction is important.

Apple says that if you erase an Apple Watch directly without the paired iPhone, the data is removed but Activation Lock remains.

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

For sale, proper unpairing is preferable.

Sell My iPhone also has a dedicated walkthrough:

How to unpair your Apple Watch ready to sell

What if I have already sold the Watch but forgot to remove Activation Lock?

Apple provides a remote option.

The legitimate owner can sign into Find My through iCloud and remove the device from their account.

Apple's Activation Lock removal instructions

However, dealing with this before posting the Watch is much easier for everyone.

Do I need the charger when selling an Apple Watch?

For Sell My iPhone, yes.

Its preparation guide says ordinary devices do not require chargers or original packaging, but specifically makes an exception for smartwatches:

smartwatches should include the charger and strap.

So before creating the trade-in, find:

• the Apple Watch;
• compatible charger;
• strap.

Read Sell My iPhone's device preparation guide

Do I need the original Apple Watch box?

Sell My iPhone's preparation guidance specifically mentions the charger and strap rather than requiring the original retail packaging for used smartwatches.

So if the box disappeared years ago, that does not automatically mean the Watch cannot be sold.

Focus first on:

• exact model;
• functionality;
• condition;
• battery;
• charger;
• strap;
• account removal.

When is the best time to sell an Apple Watch?

Usually, once you have decided you no longer need it.

That is different from saying everyone should upgrade every year.

If your Watch still works and you use it every day, keeping it may be far better value than replacing it.

The financial calculation changes after an upgrade.

Once a Watch becomes unused, waiting rarely helps

Over time:

• the hardware becomes older;
• new generations appear;
• batteries age;
• software support changes;
• more second-hand stock reaches the market.

Those factors do not guarantee a smooth downward price curve every month, but consumer electronics generally do not become more commercially attractive simply by sitting unused.

Sell My iPhone's own old-tech guide encourages owners to check whether unused electronics can be sold or reused before treating them as waste.

Read: What to Do With Old Tech in 2026 — Sell, Reuse, Donate or Recycle?

Should I sell my Apple Watch immediately after upgrading?

Wait until you know the replacement is staying.

A sensible sequence is:

1. Set up the new Watch.
2. Confirm your Health and Activity information is present.
3. Make sure you are happy with the replacement.
4. Check the value of the old Watch.
5. Unpair the old device properly.
6. Package and send it.

Apple notes that unpairing through the paired iPhone attempts to create a backup that can be used when setting up another Watch.

That means you do not need to choose between protecting your data and selling the old hardware.

Is keeping an old Apple Watch as a backup worthwhile?

Sometimes.

A backup Watch could be useful if:

• you regularly damage watches;
• you need another device while one is serviced;
• somebody else in the household may use it;
• you use different Watches for different activities.

But be realistic.

If you upgraded a year ago and the previous Watch has not been switched on since, it is probably not functioning as a meaningful backup.

It is simply unused technology.

Should I sell privately or use a trade-in service?

Both approaches have advantages.

Selling privately

A private sale can sometimes produce a higher headline price.

However, you may need to handle:

• photographs;
• listing creation;
• buyer messages;
• negotiations;
• fees;
• postage;
• disputes;
• payment risk.

Trade-in

A trade-in service prioritises convenience.

With Sell My iPhone, the current process is essentially:

1. identify the device;
2. receive a quote;
3. send the device;
4. have the condition checked;
5. receive payment if everything matches. 

Neither route is automatically best.

Compare the net money and effort, not just the highest advertised number.

How should I grade my Apple Watch?

Be conservative and accurate.

Before choosing a condition, inspect the Watch under good lighting.

Check the screen

Look for:

• scratches;
• cracks;
• chips;
• dead pixels;
• touch issues.

Check the case

Look at:

• corners;
• Digital Crown;
• side button;
• sensor housing.

Test the controls

Confirm that:

• Digital Crown rotates;
• Digital Crown presses correctly;
• side button works;
• touchscreen works across the full display.

Check charging

Put it on its charger.

Make sure charging begins consistently.

Check the battery

Open Battery Health and note Maximum Capacity.

Check connectivity

Where relevant, test:

• Bluetooth;
• Wi-Fi;
• Cellular.

An honest grade reduces the chance of receiving a revised quote after inspection.

Can I sell a completely dead Apple Watch?

Possibly.

Sell My iPhone's general FAQ says the company may buy completely dead devices when repair and resale remain viable and advises customers to provide details first.

That does not mean every dead Apple Watch will have a value.

The exact generation and failure matter.

A recent premium Watch with one repairable fault is economically different from an extremely old device with several failures.

What about water-damaged Apple Watches?

Sell My iPhone states that it avoids water-damaged devices because it does not regard them as reliably repairable, although it can recycle such devices free of charge.

This is particularly relevant to watches because water resistance can create false confidence.

A Watch originally sold with water resistance is not guaranteed to remain equally resistant forever after years of wear, impacts or repairs.

If you know the Watch suffered liquid damage, describe it honestly.

What if my Apple Watch has no resale value?

It may still need proper recycling.

Smartwatches contain electronics and rechargeable batteries.

Sell My iPhone says devices without resale value can still be recycled through its process.

That is preferable to leaving a genuinely unusable Watch in a drawer indefinitely or treating it as ordinary rubbish.

A simple example: Series 6 versus Series 10

Imagine two owners.

Owner A: Apple Watch Series 6

The Watch still works, but it has sat unused since an upgrade.

Sell My iPhone's current example for a 40mm GPS model is £25.

The owner can decide:

• £25 is worthwhile, so sell;
• give it to somebody;
• keep it as a genuine spare;
• recycle it later if it ceases to have value.

Owner B: Apple Watch Series 10

The owner upgraded again and now has a Series 10 42mm GPS + Cellular unused.

The live Sell My iPhone example is £125.

That is enough money that forgetting about the device in a drawer has a much clearer opportunity cost.

The principle is the same in both cases.

Check before assuming.

Why old smartwatches can still have value

There is a buyer at the other end of the market.

Not everybody wants the newest Apple Watch.

Some people want:

• a first smartwatch;
• a Watch for a teenager;
• inexpensive activity tracking;
• Apple Pay;
• notifications;
• a cheaper workout device;
• a previous-generation premium model.

This is exactly why the refurbished market exists.

Sell My iPhone's own guide to refurbished smartwatches compares older Apple Watch, Galaxy Watch and Garmin models as lower-cost alternatives to the latest hardware.

Read: Best Refurbished Smartwatches to Buy in 2026

Your unwanted Watch can therefore have useful life beyond your ownership.

How to prepare an Apple Watch for trade-in

Before sending it, use this checklist.

1. Confirm the exact model

Check:

• Series/SE/Ultra;
• case size;
• GPS or Cellular.

Use Apple's model identification guide if necessary.

2. Check battery health

Go to:

Settings → Battery → Battery Health

Note Maximum Capacity.

3. Test functionality

Check:

• display;
• touchscreen;
• Digital Crown;
• side button;
• charging;
• speaker;
• microphone.

4. Transfer anything you need

If you have bought another Apple Watch, make sure the new device is set up and your important Health and Activity information is available.

5. Unpair using the iPhone

Apple recommends unpairing through the paired iPhone before sale. This erases the Watch and removes Activation Lock.

6. Remove any Cellular plan

Apple says sellers of a GPS + Cellular Watch should remove the mobile plan from the Watch and may also need to contact the network provider to cancel the subscription.

7. Find the charger and strap

Sell My iPhone asks smartwatch sellers to include both.

8. Check the condition honestly

Do not hide scratches, cracks or faults.

9. Request a current quote

Values change over time, so use the live price rather than an old article or screenshot.

Check the current value of your Apple Watch

The key takeaway

Your old Apple Watch may still be worth significantly more than you expect.

Current Sell My iPhone examples range from around £25 for selected Series 6 models to £330 for Apple Watch Ultra 3, demonstrating just how wide the market is.

The factors that matter most are:

• exact generation;
• case size;
• GPS or GPS + Cellular;
• condition;
• battery health;
• screen quality;
• functionality;
• Activation Lock status;
• current market demand.

The biggest mistake is simply describing the device as:

“an old Apple Watch.”

A Series 6 and an Ultra 3 are both old Watches after an upgrade, but they clearly do not represent the same amount of remaining value.

Identify yours properly.

Check the battery.

Unpair it correctly.

Find the charger and strap.

Then look at the live value before deciding whether to sell, reuse or recycle it.
