Water resistant to 50 meters. After 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. Learn more.
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. Learn more.
The Charge 5 housing is made of aluminum, glass and resin. The band is made of silicone and has an aluminum buckle.
