Questions about this item

Does the brown leather strap need special care to stay looking good?

The brown leather strap should be wiped clean with a damp cloth and kept away from prolonged moisture to maintain its appearance.

Will the heart-rate sensor stay accurate during long workouts?

The optical heart-rate sensor reads continuously during exercise; heavy sweat or a loose fit can reduce accuracy until the watch is repositioned.

How warm does the aluminum case get and does the magnetic charger make noise during all-day wear?

The aluminum case stays near skin temperature and the magnetic charger is silent, so all-day wear produces no noticeable heat or sound.
