No. These shavings are harmless—just a sign your band is aging. But if you see heavy flaking, cracks, or skin irritation, replace the strap.

How to prevent it

Clean with mild soap and water.

Rotate between different bands.

Avoid constant rubbing on hard surfaces.

Invest in a higher-quality replacement.

Bottom line:
Those strange Velcro-like shavings aren’t dangerous—they’re just your watch strap wearing down. A little care and the occasional replacement will keep your band (and wrist) in top shape.
