In 1978 Swiss watch manufacturer IWC (International Watch Companie Schaffhausen) launched a series of watches in cooperation with Prof. F.A. Porsche that carried the logo "Porsche Design". In 1980 F.A. Porsche began designing the diver’s watch "Ocean" for IWC.
The so-called Ocean set comprised three military editions: a combat diver’s watch, a clearance diver’s watch and a mine clearance diver’s watch. Two "IWC Porsche Design Ocean" versions for the civilian market were produced at the same time – the "Ocean 2000" and the slightly smaller "Ocean 500". These models were launched in 1982; the designations 2000 and 500 indicate their water resistance of 2,000 and 500 metres respectively.
Both "civilian" versions as well as the Ocean versions designed for the navy are highly sought after models –the timeless design by F.A. Porsche as well as his first-time use of titanium in a wristwatch and the general history of the Ocean watches have made them a legend amongst the collectors.
