After swimming or getting the band wet, we recommend drying the band because, as with any wearable device, it’s best for your skin if the band is clean and dry. We do not recommend wearing Fitbit Versa 3 in a hot tub or sauna. Care Give your wrist a rest by taking the band off every now and then. If the band gets wet or you sweat in it, remove and completely dry the band before putting it back on. Materials Versa 3 includes a band made of a flexible material similar to that used in many sports watches, as well as an aluminum watch case. Heart Rate Like all heart rate tracking technologies, accuracy is affected by physiology, location of device and different movements.
