The classic band is made from a flexible, durable elastomer material, similar to the material used in many sports watches, and features a surgical stainless steel clasp. Classic accessory bands are tested for up to 5 ATM, meaning they are sweat, rain, and splash resistant, but should not be worn while swimming. We recommend removing the tracker before showering, as it is best for your skin if the band remains dry and clean.

If the classic band gets wet or if you sweat while wearing it, take it off and ensure that the band is completely dry before putting it back on. Occasionally remove the band to give your wrist a break. Size S fits wrists with a circumference of 14 - 17 cm. Size L fits wrists with a circumference of 17 - 20.5 cm.
