The prototype was built in 1982 as a watch for mine clearance divers and designed by the legendary Ferdinand A. Porsche. The version for non-military use, the Ocean 2000, was the first watch with a pressure-resistance of 200 bar and was much coveted by collectors. The Aquatimer Automatic 2000 is a reliable backup system, even for the most exacting underwater missions. The 46-millimetre titanium case ensures the dial is legible and leaves enough room for the robust IWC-manufactured 80110-calibre movement. The chunky external rotating bezel can be adjusted easily even when wearing gloves and, as the name SafeDive system suggests, offers the diver a very high level of safety. The rubber strap is optionally available in an XXL version that can be worn over a neoprene suit or a drysuit. For the designers, only one motif was thought appropriate for the engraving on the back of the cover: the classic diving helmet worn by deep-sea divers.
