Six Weeks Out: The Pre-Launch Value Window Is Open
The Apple Watch Series 12 is widely expected to launch alongside the iPhone 18 Pro models in September 2026. That means if you're sitting on a Series 10 or Series 11, you've got a narrow window before the second-hand market reprices itself. This happens every year — and with smartwatches, it's brutal.
Apple Watch depreciates faster than any other Apple product, with an average value loss of around 83% over the first two years. The moment a new model is announced, that curve steepens sharply. Right now, you're still on the better side of it.
Apple's own trade-in page is already offering £30–£255 off a new Apple Watch when you trade in an older model — a clear signal that the churn window is open and Apple knows it.
What the Series 12 Actually Brings
The upgrade case matters here, because it determines how much demand shifts away from older models. The Series 12 combines the first new Apple Watch chip since 2023 with watchOS 27's rebuilt Siri and more on-device AI — the S12 chip replaces the processor architecture Apple has reused since the Series 10.
Confirmed at WWDC on 8 June 2026, watchOS 27 brings Siri AI to Apple Watch for the first time as a standalone app. The S12 chip is specifically designed for the best AI performance on watchOS 27 — older chips will run the software but may not handle every AI feature as smoothly.
Rather than adding bulky new hardware, Apple is reportedly using internal space to fit a larger battery, and combined with the efficiency of the S12 chip, we could see a genuine jump in real-world battery life.
That said, there's no meaningful design change expected — Gurman says a major redesign is unlikely, with the same rounded square case and display sizes. A true case redesign is not expected until 2027 or 2028. If you were waiting for a complete overhaul, you'll be waiting a while yet.
Should I sell my Apple Watch Series 10 now, before Series 12 launches?
Yes — if selling is something you're considering, now is the right time. The Series 11, Ultra 3, and SE 3 all contain the same S10 chip as the previous year's models, which means the Series 10 is now two chip generations behind the incoming Series 12. Buyers shopping second-hand know this, and prices reflect it. Values will soften further the moment Apple takes the stage in September. Selling six weeks out, while pre-launch buzz is at its peak, puts more money in your pocket than waiting until the keynote livestream ends.
Is the Apple Watch Series 11 still worth buying in 2026?
It depends entirely on what you're starting from. watchOS 27 runs on models from Series 9 onwards, though the latest AI features may be chip-dependent — so a Series 11 will get the software update but potentially not the full AI experience. If you already own a Series 11, there's little reason to upgrade — the Series 12 doesn't appear to offer anything dramatic enough to make it stand out from its predecessor.
For buyers coming from a Series 8 or older, though, a refurbished Series 11 right now is genuinely good value. At recent street prices, the Series 11 has been sitting well below Apple's own RRP, making it one of the best-value entry points for Apple Watch in years. Buy one now on the refurbished market and you sidestep the post-launch price spike that hits new stock in October. Browse our refurbished Apple Watch range to see what's currently in stock.
Should I wait for Apple Watch Series 12 or buy a refurbished model now?
If you want the S12 chip and on-device Siri AI at launch, wait — September is close enough that it makes no sense to buy new right now. But if your budget is under £250 and you need a capable, warrantied Apple Watch today, a refurbished Series 10 or 11 is a strong choice. The current Series 11 is an excellent device that will last years. It'll also receive watchOS 27 when it drops — you just won't get every AI feature running on-chip.
One practical consideration: when Series 12 ships, refurbished Series 10 and 11 prices on the secondary market will dip as trade-ins flood back in. If you can wait a few weeks after launch, you may find the same devices at a slightly lower price. If you can't, current refurbished prices are still fair — just buy from a seller who includes a warranty.
The Depreciation Reality for Series 10 Owners
Apple Watch holds value worse than any other Apple product category. Smartwatches depreciate fast because new models arrive annually with better processors, sensors, and features. The Series 10 launched in September 2024 — by the time Series 12 lands, it'll be two full cycles old. That's the point at which the resale curve gets steep.
Apple's trade-in programme gives you store credit, not cash, and it locks you into buying another Apple product immediately. If you want actual money — to put towards anything — selling independently will almost always return more. The key is timing: sell before the announcement, not after.

Who Should Actually Buy a Refurbished Series 10 or 11 Right Now
- Budget buyers under £200–£250: A refurbished Series 10 or 11 with warranty is significantly cheaper than a new Series 12 will be at launch, and does 95% of the same job.
- First-time Apple Watch buyers: You don't need the newest chip to get the health tracking, activity rings, and notifications that make Apple Watch useful daily.
- Parents buying for teenagers: A solid refurbished model is far less of a loss if it gets scratched or damaged.
- Series 7 or 8 owners who need an upgrade now: Moving to a refurbished Series 10 or 11 is still a meaningful step up in display, chip, and battery — at a fraction of new Series 12 pricing.

The Bottom Line
Series 10 owners: your window to sell at a reasonable price is now, not in October. The S12 chip is a meaningful generational jump after three frozen generations, and watchOS 27 with Siri AI is the biggest software upgrade Apple Watch has had in years — that combination will shift buyer attention firmly to the new model the moment it's announced. Get ahead of that.
Series 11 owners: you're in a better position. The gap between your watch and the Series 12 is smaller, and watchOS 27 will still arrive on your wrist in September. Hold unless the cash is genuinely useful.
Budget buyers: the refurbished market on Series 10 and 11 is solid right now, and will stay solid. See what's available in our refurbished Apple Watch collection — or if you're ready to sell, get a quick quote and we'll sort the rest.
