Your Apple Watch's model number tells you which Series it is, and Techtree's price starts there. On the paired iPhone, open the Apple Watch app, tap My Watch, then General, then About, and tap Model Number so it shows a number that starts with "A"; the table below matches it to a Series. As of September 30, 2026, Techtree pays up to $521 for a Series 12 in Good condition, $277 for a Series 11, $150 for a Series 10 and $108 for a Series 9, down to $27 for a Series 5. Those figures are the best configuration we buy; in aluminum, the same four newest watches are worth up to $197, $171, $131 and $106.
This guide lines up every Series from 5 to 12 and the two newest SE models: how to tell them apart, what each is worth in every condition, what a year of age costs, and how to get the top offer. The Ultra has its own guide: Apple Watch Ultra 1 vs 2 vs 3 vs 4.
At a glance (Techtree, as of September 30, 2026):
- In Good condition, best configuration, Techtree pays up to $521 (Series 12), $277 (Series 11), $150 (Series 10), $108 (Series 9), $78 (Series 8), $56 (Series 7), $43 (Series 6) and $27 (Series 5).
- Comparing the best aluminum configuration of each (aluminum is the one case every generation comes in), a Good-condition Series 11 is worth 87% of a Series 12, a Series 9 54% and a Series 5 14%.
- The case matters most on new watches: a 46mm titanium Series 11 is worth $277 in Good condition, a 46mm aluminum one with cellular $171.
- A Series 11 with fingernail-deep scratches (Fair) keeps 68% of its Good price (best configuration); with a cracked display that still works (Minor Damage) it is worth up to $70.
- watchOS 27 runs on the Series 9 and later and the SE 3. The Series 5 to 8 and the SE (2nd generation) do not get it, and Techtree still buys all of them.
- Turn off Activation Lock before you ship: Techtree cannot buy a watch that is still locked, reported lost or stolen, or has a balance owed.
Which Apple Watch do I have?
Apple puts the answer in the Watch app. On the paired iPhone, open Apple Watch, tap the My Watch tab, then General, then About. The Model Number field shows a part number that starts with "M"; tap it and it switches to the model number, which starts with "A". Find that number below, where the smaller case is always listed first.
| Watch | GPS | GPS + Cellular |
|---|---|---|
| Series 12 (2026) | A3581 (42mm), A3584 (46mm) | A3582 (42mm), A3587 (46mm) |
| Series 11 (2025) | A3331 (42mm), A3333 (46mm) | A3335 (42mm), A3337 (46mm) |
| Series 10 (2024) | A2997 (42mm), A2999 (46mm) | A3001 (42mm), A3003 (46mm) |
| Series 9 (2023) | A2978 (41mm), A2980 (45mm) | A2982 (41mm), A2984 (45mm) |
| Series 8 (2022) | A2770 (41mm), A2771 (45mm) | A2772 (41mm), A2774 (45mm) |
| Series 7 (2021) | A2473 (41mm), A2474 (45mm) | A2475 (41mm), A2477 (45mm) |
| Series 6 (2020) | A2291 (40mm), A2292 (44mm) | A2293 (40mm), A2294 (44mm) |
| Series 5 (2019) | A2092 (40mm), A2093 (44mm) | A2094 (40mm), A2095 (44mm) |
| SE 3 (2025) | A3324 (40mm), A3325 (44mm) | A3326 (40mm), A3328 (44mm) |
| SE, 2nd generation (2022) | A2722 (40mm), A2723 (44mm) | A2726 (40mm), A2727 (44mm) |
Those are the numbers Apple lists for North America (from the Series 9 and the SE 3 on, Europe and Asia Pacific use them too). A watch bought elsewhere can carry a different one:
| Watch | GPS, other regions | GPS + Cellular, other regions |
|---|---|---|
| Series 12 | A3583, A3585 (China mainland) | A3586, A3588 (China mainland) |
| Series 11 | A3450, A3451 (China mainland) | A3452, A3453 (China mainland) |
| Series 10 | A2998, A3000 (China mainland, Indonesia) | A3002, A3206 (China mainland) |
| Series 9 | One number everywhere | A2983, A2985 (China mainland) |
| Series 8 | One number everywhere | A2773, A2775 (Europe, Asia Pacific); A2857, A2858 (China mainland) |
| Series 7 | One number everywhere | A2476, A2478 (Europe, Asia Pacific, China mainland) |
| Series 6 | One number everywhere | A2375, A2376 (Europe, Asia Pacific, China mainland) |
| Series 5 | One number everywhere | A2156, A2157 (Europe, Asia Pacific, China mainland) |
| SE 3 | A3391, A3392 (China mainland) | A3327, A3329 (China mainland) |
| SE, 2nd generation | One number everywhere | A2725, A2724 (Europe, Asia Pacific); A2855, A2856 (China mainland) |
Three things the tables cannot settle on their own:
- The number does not tell you the case. A titanium and an aluminum Series 11 with cellular share A3335 and A3337, for example, so our quote asks for the case material separately. Every generation here came in aluminum; stainless steel was offered on the Series 5 to 9, titanium on the Series 5, 6, 7 and 10 to 12, and ceramic only on the Series 5 and 12. Every SE is aluminum only. Nike and Hermès editions carry the numbers of their Series.
- No iPhone to hand? Apple says the engraving on the back of the watch shows the case size and more. Among the watches in these tables, 40 or 44mm means a Series 5, a Series 6 or an SE; 41 or 45mm a Series 7, 8 or 9; 42 or 46mm a Series 10, 11 or 12.
- Look-alikes. The first SE (A2351 to A2356) comes in the same 40mm and 44mm aluminum cases as the SE (2nd generation); the back tells them apart, since Apple lists a ceramic back for the first SE and a molded nylon composite back for the second. We do not list the first SE or the Series 4 and older.
What is each Apple Watch Series worth?
These are Techtree's own prices as of September 30, 2026, for a complete, working watch with its band and charger. Each figure is the best configuration we buy in that condition, the same "up to" as our trade-in price index; on the Series 10 to 12 that is a titanium or ceramic case, and aluminum is worth less (see the case and cellular section). Tap a model for every size, case and connectivity, and its price history.

A watch still sealed in its original box (our Brand New grade) is worth a little more than Flawless: up to $570 for a Series 12 against $560, for example. Selling an unopened Apple Watch covers sealed and open-box watches.
Apple Watch SE
The SE (2nd generation) and the SE 3 come only in aluminum, in 40mm and 44mm.
| Model | Flawless | Good | Fair | Minor damage | Broken |
|---|---|---|---|---|---|
 Apple Watch SE 3Released 2025 |
$96 | $67 | $61 | $38 | $11 |
 Apple Watch SE (2nd generation)Released 2022 |
$57 | $44 | $27 | $24 | $7 |
The SE sits well below the Series from the same year: as of September 30, 2026, an SE 3 with cellular is worth up to $67 in Good condition, against $171 for an aluminum Series 11 with cellular, and both launched in 2025. Every model we buy, in every condition, is in our trade-in price index.
How much value does each year cost?
Aluminum is the one case every Series comes in, so it gives the cleanest read of what age costs. This is the best aluminum configuration of each generation in Good condition:
Read down the ladder: an aluminum Series 11 is worth 87% of a Series 12 in the same condition, a Series 10 66%, a Series 9 54% and a Series 8 37%; by the Series 5, $27 is left.
Our reading of the price book (a judgment, not a forecast): value comes off in steps, one per generation, rather than in a single cliff at a particular age. The ladder compares different generations priced on the same day, not one watch followed over time, but Apple has announced a new Series every September since the Series 5 in 2019, and each one adds a step above the watch you already own. For the wider picture across every Apple Watch, see how fast every Apple Watch loses value.
Do the case and cellular change the value?
The case matters most on the newest watches. In Good condition as of September 30, 2026, comparing the larger size with cellular, a 46mm Series 12 is worth $521 in ceramic, $391 in titanium and $197 in aluminum. A 46mm Series 11 is worth $277 in titanium against $171 in aluminum, and a 46mm Series 10 $150 against $131. On a 45mm Series 9 it is $108 for stainless steel and $106 for aluminum. Our reading of today's prices: a titanium, ceramic or stainless steel case pays most on the newest watches, and a few generations back it adds little or nothing. Aluminum vs titanium vs stainless steel compares the cases in more depth.
On the newest watches, cellular moves the price less than the case does. From the Series 5 to the Series 12, Apple sold every titanium, stainless steel and ceramic model only as GPS + Cellular, so the choice only exists in aluminum. On a 46mm aluminum Series 12 in Good condition, GPS + Cellular is worth $197 and GPS only $177; on a 45mm aluminum Series 9 the two are $106 and $103. GPS vs Cellular goes deeper on whether cellular pays.
Scratched or cracked: what condition costs
Apple Watches take knocks on door frames and desks. That is fine: we grade what we find, and a worn watch still sells.
| Condition | Series 11 | Series 9 | What it means |
|---|---|---|---|
| Good | $277 | $108 | Light scratches or dents that do not catch a fingernail |
| Fair | $189 (68%) | $81 (75%) | Fingernail-deep scratches, major dents or mild housing damage, with no cracked glass |
| Minor damage | $70 (25%) | $21 (19%) | One issue, such as a cracked display that still works fully, or battery health below 80 percent |
| Broken | $20 | $6 | More than one issue, water damage, or does not power on |
Prices are the best configuration as of September 30, 2026; percentages are the share of that model's Good price. Do not polish or repair the watch first. Pick the grade that matches and ship it as it is: a Series 11 in Fair or a Series 9 with Minor Damage opens the quote with that grade already selected. The how we grade page lists every check, and what a cracked Apple Watch is worth covers cracked displays in more depth.
Which Apple Watch gets watchOS 27?
watchOS 27, Apple's current version, runs on the Series 9 and later and the SE 3, as well as the Ultra 2 and later. The other watches in this guide stay on an earlier version:
| Watch | Newest watchOS it runs |
|---|---|
| Series 9, 10, 11 and 12; SE 3 | watchOS 27 |
| Series 6, 7 and 8; SE (2nd generation) | watchOS 26 |
| Series 5 | watchOS 10 (10.6.1) |
What it means for value: our quote does not ask which watchOS a watch runs. The offer depends on the generation, the case, the size, the connectivity, the condition and whether the band and charger come with it, and we buy the Series 5 to 8 and the SE (2nd generation) at the prices above. What the cutoff changes is the watch itself: a Series 8 or older, or an SE (2nd generation), will not get watchOS 27 however long you keep it. If a newer watch has already replaced it, it is worth more to you as cash than in a drawer.
How do you get the top price?
- Back it up and unpair it. Keep the watch next to its iPhone, open the Apple Watch app, tap My Watch, then All Watches, tap the info button next to the watch and tap Unpair Apple Watch. Enter your Apple Account password when asked: that is the step that turns off Activation Lock. Apple says unpairing erases the watch and restores its factory settings, and that your iPhone tries to back the watch up when you unpair. The full walkthrough, including a watch without its iPhone, is in how to reset an Apple Watch.
- Check Find My. Sign in at iCloud.com/find and make sure the watch no longer appears in your devices. If it does, erase it there and then remove it from your account before you ship.
- Remove the cellular plan. On a GPS + Cellular watch, choose to remove the plan when you unpair, then contact your carrier to cancel the line.
- Send the band and charger. The price assumes a complete watch. If either one is missing, say so in the quote, and the offer you accept already reflects it.
- Choose the condition honestly. If the scratches catch a fingernail, choose Fair. A watch that matches its grade is paid as quoted; if it arrives in a different condition, we send a revised offer. You have 7 days to accept or decline it, and no reply counts as accepting.
- Ship within the price lock. Your price is locked for 21 days, and a free prepaid shipping label comes with your order.
What we cannot buy: a watch with Activation Lock still on, one reported lost or stolen, or one with a balance still owed on it. Activation Lock has to be off before the watch leaves your hands, not after; how to reset an Apple Watch covers every way to clear it.
