the 2 was debatable.... ppl said they jumped in pools with em on accident and they were fine, yet instructions say dont even shower. Ive rinsed mine off with water just fine (no button pressing till dry)
The charge 3 is supposed to be water resistant to 50 meters, prolly because it doesnt have any real "button" to worry about.
heres what they say:
Swimproof
Fitbit Charge 3 is water resistant to 50 meters, automatically tracks your swims and can be worn in the pool or shower.
That said, realworld testing I dunno........... Im waiting still as I preordered about a month ago
