Editor's Notes

IWC SCHAFFHAUSEN has revisited its robust 'Aquatimer Automatic' watch again and again since it was introduced in 1967, and it remains one of the preferred choices of professional and recreational divers alike. Animated by an in-house calibre 32111 movement with a substantial 120-hour power reserve, this reference is built from corrosion-resistant stainless steel and fitted with a unidirectional rotating bezel designed to ensure safer deep dives. The black dial is illuminated with Super-LumiNova® hands and indices for improved readability, and has a central hacking seconds function for precise timekeeping.

For warranty information, please refer to details & care
