Why You’re Finding Tiny Rubber Shavings Near Your Smartwatch

Ever notice small, curled bits on your sheets, desk, or wrist after taking off your smartwatch? They look like tiny Velcro hooks—but they’re actually fragments of your watch band. If your strap is made of silicone or rubber, these little curls are just a normal sign of wear and tear.

Over time, friction from everyday movements—typing, adjusting the strap, or resting your wrist—causes the band to break down. Sweat and body oils can speed up this process, especially if the strap is lower quality or hasn’t been cleaned regularly. Cheaper materials tend to degrade faster, while higher-end bands made from materials like fluoroelastomer hold up better over time.
