Editor's Notes

IWC SCHAFFHAUSEN has been manufacturing professional diving watches for almost 50 years. This 'Expedition Jacques-Yves Costeau' chronograph references the Swiss watchmaker’s first style, released in 1967, but pays homage to the titular ‘Le Commandant', whose profile is engraved on the case back. Evolving to meet the demands of 21st century divers, this stopwatch-enabled piece is constructed with an externally operated internal rotating bezel with a SafeDive locking system and push-buttons that can be activated underwater, even at 300m.

We offer an eight-year warranty for all working parts and manufacturing faults for IWC SCHAFFHAUSEN watches. For more information, contact one of our experts by emailing
