IWC - Ocean 2000 Ref. 3500 Porsche Design Titanium case on strap
This rare automatic model, introduced in 1982, Ocean 2000Ref. 3500 Porsche Design. It's 2000 m water resistance rating easily exceeded the combined pressure ratings of the contemporaneous Rolex Sea Dweller (1220 m) and Seiko Pro Diver (600 m); achieved with a simple screw back case, organically shaped and modestly sized relative to the Japanese titan at 42 mm in diameter and 12.6 mm in thickness, as well as being lighter than either. Porsche Design opted for the same ergonomic repositioning of the crown used by Seiko for its divers watches since the 1960's. Condition are overall excellent, fitted by the original military style strap.
