Silicone:

Water resistance
Water resistant up 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.
Heart rate
Like all heart rate tracking technologies, accuracy is affected by physiology, location of device and different movements.
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.
