Does watch protection film damage the watch?

Short answer: a proper TPU film with a residue-free acrylic adhesive does not damage a watch. We've removed our own film from 200+ watches with zero exceptions.

Long answer: the wrong film absolutely can. Three things to check before buying any watch protection film.

One — adhesive type. Acrylic adhesives peel clean. Silicone adhesives bond too aggressively to coated surfaces and can pull lacquer off vintage dials. Pressure-sensitive adhesives leave a haze on sapphire. Always ask which adhesive is being used.

Two — material. TPU (thermoplastic polyurethane) flexes with case curvature and self-heals under body heat. PET (the cheap default) is rigid, lifts at the corners, and yellows. PU film is a middle ground — flexible but not self-healing.

Three — cut precision. A film cut even 0.3mm too large will lift at the bezel edge. A film cut too small leaves an unprotected ring. Both are visible. Both are uncomfortable. Pre-cut to your specific reference is the only way.

If the brand can't answer all three questions, walk away. If they can, the film will protect your watch for years without consequence.
