Tight integration with iPhone, Comprehensive fitness tracking, Blood oxygen and ECG sensors are useful & reassuring, Long battery life

Siri can be hit & miss still, Cellular version gets expensive

The Apple Watch has been our longstanding Editors' Choice for its excellent performance, unparalleled app selection, and ample health and fitness tracking features. With the Series 6 (starting at $399), Apple builds upon its flagship smartwatch with the addition of a blood oxygen saturation sensor that calculates your SpO2 level on demand and captures periodic background measurements when you're sleeping and inactive. Putting this technology in a consumer wearable has never been more important given the global COVID-19 pandemic, as it indicates how well your circulatory and respiratory systems are delivering oxygenated blood to your body, and can help you gauge whether a hospital visit is necessary. Beyond this, Apple's changes include a faster processor, an always-on altimeter that lets you see your elevation in real time, and a bump in screen brightness when your wrist is down.

Comprehensive app ecosystem; Solid build quality and performance; Improved screen brightness

Poor battery life; Requires iPhone; Premium price tag

The Apple Watch Series 6 is the best smartwatch on the market for an iPhone. It has better integration with the iPhone and is fast, fluid and responsive in a way that many rivals simply aren’t.

excellent haptics; great always-on screen; ECG; great health tracking; great activity tracking; 50m water resistance; solid battery; comfortable; quick-swap straps; Apple Pay.

expensive; only works with an iPhone; sleep tracking not great; blood oxygen data not that useful.

The Apple Watch Series 6 continues Apple's smartwatch dominance, with solid improvements across the board. Many of its features can be found in cheaper competitors, but not the overall experience.

Great range of health sensors; Brighter always-on screen is impressive; Excellent app support and software; Solid battery life for general use; Great new colour options

iPhone-only still; Not a big leap forward from Series 5; New sleep tracking is basic; Won't satisfy truly hardcore fitness fans

With the blood oxygen reading that is just a tap away, the Apple Watch series 6 makes great sense for anyone at the forefront of the fi...

Very easy to use and love it very much
