What reviewers say

Reviewers agree it improves on the original, with a slimmer, lighter case, better battery life, a brighter display and new diving support, making it a strong choice for active Android owners. The common criticisms are a case that is still large and chunky, and workout tracking accuracy that falls short of the best GPS sports watches; Tom's Guide also found it pricey.

Pros and cons

Pros

Up to 60 hours with the always-on display on (80 hours with it off), and 40% charge in about 30 minutes
Up to 5,000 nits, the brightest smartwatch display at launch by Samsung's market research
10ATM, IP69K and EN13319 dive-instrument certification, with depth, dive time and water temperature to 40 m

Cons

One 47 mm size only, weighing 61.5 g without band
Doesn't work with iPhones, and the ECG, blood pressure and sleep apnoea features need a Samsung Galaxy phone
No-decompression limit tracking isn't supported out of the box; full dive-computer features need a separate app
