Garmin Descent Mk3

“all smartwatches require an app: 1) for connectivty and providing those notifications etc; 2) for the data - a lot of it in most brands is crunched on servers/app and then for being able to see long term trends/history. Note that no watch is waterproof - the closest are dive watches, but for swimming a 5atm watch is good, for high pressure/speed water sports (presssure washers etc) a 10atm should be fine. More than that and you need a dive rated watch (garmin and suunto are best options). He - durable - if he wants watch to reply/make texts/calls then going to limit and reduce best options - maybe sapphire screen and or high bezels to protect glass. If wear os means looking at ticwatch atals (only 5atm), oneplus watch 2 or 3 (but not enough bezel protection & 5atm) or samsung GW Ultra (bezel protection lacking 10atm). Personally best options are going to be 10atm watches with decent bezels - some variants may include sapphire glass: amazfit t-rex, huawei ultimate, garmin instinct or fenix (and its variants like epix etc), coros vertix, polar grit and suunto race / vertical (not race s as only 5 atm). If he wants the prime music offline then garmin or the wear os options (samsung, oneplus, ticwatch) are only options. Yoursellf - fitbit but only 5atm / garmin offer 5 atm or 10 atm and or dive watches. If need women's health (making an assumption that could be wrong - going on sleek) - then this can make a difference. Wear os is out for you due to battery life though if can use a 47mm oneplus watch 2 or 3 that may work for you but will have to run it out of wear os mode. Suggest maybe starting with garmin as most offer +9 days and maybe start with garmin lily 2 active (they don't come sleeker) or maybe vivoactive 5 as starting point.”
