The Watch 9 just landed — and it's already changed what your Watch 8 is worth
Samsung announced the Galaxy Watch 9 on 22 July 2026 at Galaxy Unpacked in Old Billingsgate, London, alongside the Z Fold 8 series and Galaxy Glasses. Pre-orders opened the same afternoon, with retail availability confirmed for 7 August. The moment that announcement went live, the used market for Watch 8 and Watch 7 shifted — and if you're sitting on either, you need to decide what to do with it fairly quickly.
This isn't scaremongering. It's just how smartwatch depreciation works. Every generation launch resets expectations on what the previous model is worth, and the window to sell before the floor drops further is always narrower than it feels.
What's actually new in the Galaxy Watch 9?
The Watch 9 doesn't look dramatically different on your wrist. Samsung has kept the same squircle case shape in 40mm and 44mm, and the display size hasn't changed either. The meaningful differences are under the hood.
The biggest change is the processor. The Watch 9 swaps Samsung's in-house Exynos W1000 — the same chip used in both the Watch 8 and Watch 7 — for Qualcomm's new Snapdragon Wear Elite. That chip upgrade brings better AI performance and improved efficiency, with Samsung promising better battery life as a result. Speaking of battery: the 40mm Watch 9 gets a 390mAh cell, up from 325mAh in the Watch 8's 40mm — a change that directly addresses the Watch 8's most common criticism, which was needing a daily charge.
The Watch 9 also ships with One UI 9 Watch on Wear OS 7, one generation ahead of the Watch 8's software — though Samsung will likely push that update to older models eventually.
What you're not getting: a new design, a bigger display, or a rotating bezel. Samsung has dropped the Classic variant entirely this year, so there's no Watch 9 Classic coming.
Is the Galaxy Watch 9 worth the upgrade from a Watch 8?
Probably not if you bought your Watch 8 in the last twelve months. The design is identical, the health-tracking feature set is largely the same, and the battery improvement — while real — isn't transformative. The software upgrade will arrive on Watch 8 anyway. The new Qualcomm chip is the one genuinely compelling reason to upgrade, and how much that matters depends on whether you're someone who pushes AI features hard or just wants accurate health tracking and notifications. For most people, the Watch 8 will still do that job perfectly well for another two years.
That changes if you're on a Watch 7. That's now two full generations behind, and some of the newer health features — including those introduced with the Watch 8 — won't backport. At that point, upgrading makes more sense, but not necessarily to the Watch 9 at full price.
How much has the Galaxy Watch 8 dropped in value after the Watch 9 launch?
Samsung launched the Watch 8 in July 2025 with an RRP of £319. By the time the Watch 9 was announced, the Watch 8's official retail RRP had already dropped to around £299 — but open-market and used values move faster than retail pricing. Trade-in programmes set a useful floor: Samsung's own US trade-in programme values the Watch 8 at around $150 against the Watch 9, with the Watch 7 coming in lower still. UK trade-in values from retailers tend to track those directions, converting to meaningfully less than what you paid.
The pattern with smartwatch launches is consistent: used values typically drop 20–35% in the weeks immediately following a successor announcement, then stabilise once initial demand for the new model is absorbed. If you're planning to sell, the day or two after an announcement — before every other seller lists theirs — is usually the best window. That window is narrowing now.
Should I sell my Galaxy Watch 8 now, or hold on?
Sell now if you're not getting daily use from it, or if you've been thinking about upgrading. The Watch 9 won't be in everyone's hands until August, which means demand for a used Watch 8 in good condition is still reasonable today. Wait another four to six weeks and you'll be competing with everyone who traded theirs in and had it reflooded back into the secondhand market — at lower prices.
Hold if you're actively using it and have no immediate plans to upgrade. It's still a good watch, and grinding through the depreciation curve is fine if it's serving you well. Just don't expect to recover much more than 40–50% of your original outlay if you wait until the end of the year.
If you've got a Watch 7 that you've not touched since upgrading your phone, that's closer to dead weight.

The other angle: should you buy a refurbished Watch 8 instead of the Watch 9?
Here's the question fewer people are asking, but probably should be. The Watch 9 starts at £349. A refurbished Watch 8 in good condition from a reputable seller will now come in noticeably below that — and as we've covered, the two watches do virtually the same things. Same design, same display, same core health features. The Watch 8's battery life was its weak point, but if you know that going in and you're fine charging nightly, you're getting a capable, verified wearable for considerably less money.
The Watch 7 sits even further down the price curve. It uses the same Exynos W1000 chip as the Watch 8, so it's not dramatically slower, but it's missing the squircle redesign and some of the newer health sensors. For light use — notifications, steps, sleep tracking — it still holds up.
If you're considering a refurbished Samsung smartwatch, it's worth understanding how grading works before you buy. Condition grades vary between sellers, so check what's actually covered. At Tech4Cash we publish our grading criteria openly on our device condition page, so you know exactly what to expect before it arrives. You can browse what's in stock across our refurbished smartwatches collection — stock moves quickly after a new launch, because that's when people trade in the previous generation.
The bottom line
The Galaxy Watch 9 is a solid incremental upgrade. The Qualcomm chip and marginally better battery life are real improvements, and if you're buying new, £349 is the entry point. But if you already own a Watch 8, there's no compelling reason to rush. And if you're in the market for a capable smartwatch without paying flagship prices, the Watch 8's value has just moved in your favour.
Whatever side of that equation you're on — selling an older model or buying a refurbished one — the best time to act on a device launch is in the first few weeks, before the market settles. If you want to sell your Samsung watch, get a quote today. If you're buying, keep an eye on stock — post-launch is when the best refurbished deals appear.
