Despite the 47 mm case, multiple reviewers say the watch sits well and feels manageable on the wrist.
Overall fitness tracking is good enough for many users, but review evidence still shows some inconsistency in harder conditions.
In multisport and gym use, one reviewer says the watch tracked indoor training sessions reliably.

Health tracking is generally viewed as accurate and useful, especially around sleep and overnight recovery patterns.
Heart rate accuracy is one of the M2's stronger areas for many workouts, but multiple reviews still recommend a chest strap when precision really matters.
Across runs and workouts, reviewers repeatedly describe optical heart rate as close to chest straps and generally reliable.
The watch lacks built-in cellular and still depends on a nearby phone for calls or assistant functions.
Materials are practical rather than premium, combining plastic or polymer construction with nicer accents like stainless steel or mineral-style elements.
