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.
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.
The Charge 5 housing is made of aluminum, glass, and resin. The band is made of silicone and has an aluminum buckle.
Like all heart rate tracking technologies, accuracy is affected by physiology, location of the device, and different movements.
