Important Notes
This strap is an aftermarket replacement and is not an official IWC product. It is designed to be compatible with the specified IWC Aquatimer models but does not include a buckle—users must install their existing buckle. Always verify your watch model and lug dimensions before purchasing to ensure compatibility. The product comes as a standalone rubber strap with no additional accessories. For warranty details, refer to the manufacturer’s official policy. Customer feedback currently includes one review rated 1.0 out of 5 stars, which may reflect an isolated experience. To maintain the strap’s longevity, rinse it with fresh water after exposure to saltwater and avoid prolonged direct sunlight, which can degrade rubber over time.
