The Apple Watch Series 10 remains a capable wearable in 2026, according to Engadget's review. It keeps the same wide-angle OLED display, 2,000-nit brightness, and health features such as ECG, sleep apnea notifications, and cycle tracking. It also runs the current watchOS and supports Apple Intelligence, so buyers are not getting an outdated assistant or interface.
The bigger question is longevity. Engadget notes that Apple Watch models historically receive only four to six years of major watchOS updates, and the Series 10 has already seen three. The first-generation Apple Watch Ultra received just four updates, so the Series 10 may have roughly three more years of support. The reviewer also observed that the Series 10 feels more sluggish on watchOS 12 than it did on earlier versions, which could worsen over time.
Price is the deciding factor. Apple no longer sells the Series 10 directly, so buyers must use third-party retailers. Engadget found renewed units on Amazon starting around $250, well below the Series 12's $400 retail price. That discount may be worthwhile for users who accept the shorter support window and the lack of newer features like more frequent heart-rate readings, readiness scores, and 5G cellular support. For those planning to keep a watch for several years, the newer model may be the safer investment.
