In 2026, is it worth buying an Apple Watch Series 7? The short answer: yes, but only refurbished. The Series 7, launched in 2021, was the first Apple Watch with a larger display, always-on screen, tougher glass, and fast charging. Four years on, it still has ECG, SpO₂ sensor, preliminary temperature sensor, all the key health and safety features — and it supports watchOS 11. Refurbished from iOutlet, with a 24-month warranty and battery tested with specialist technical software, it's one of the best buys in the Apple Watch lineup in 2026.

Who it's for (and who it isn't)
It makes sense if:
- You want an Apple Watch with ECG and SpO₂ for under €300
- You're after the larger, bright Always-On display
- You'll use it for fitness, swimming, or hiking
- You don't strictly need the body temperature sensor
Consider Series 8 or 9 if:
- You want the body temperature sensor for cycle tracking or sleep monitoring
- You want Crash Detection (available from Series 8 onwards)
- Your budget stretches to the step up
Consider Apple Watch SE 2 if:
- You don't need ECG, SpO₂, or Always-On
- You want the lowest possible entry price for an Apple Watch
How long the Series 7 will receive updates
In 2026, the Series 7 runs watchOS 11 without limitations. Apple typically keeps Apple Watch supported for 6+ years after launch, which puts the Series 7 in line for support until at least 2027 — and likely 2028 with minor limitations.

Frequently Asked Questions
Is it worth buying the Series 7 in 2026?
Yes, refurbished. For €220–290 you get ECG, SpO₂, Always-On, a large display, watchOS 11 support, and a tested battery with a 24-month iOutlet warranty.
Series 7 or Apple Watch SE 2: which should you choose?
If you want ECG, SpO₂, Always-On, and a larger display, go for the Series 7. If you want the lowest possible price and the essentials (notifications, fitness, heart rate), the SE 2 is the more budget-friendly choice.
Does the Series 7 battery still last a full day?
Refurbished from iOutlet, yes. Every battery is tested with specialist technical software to ensure near-new performance. If it doesn't pass, the unit isn't sold.
Can I use the Series 7 with any iPhone?
It works with iPhones running iOS 17 or later. For most users with an iPhone XS or newer, you're covered.
