A Fine Titanium Automatic Sweep Seconds Bracelet Watch with Date, IWC, Porsche Design, 'Ocean' model, Circa 1990

gilt lever movement, black dial, luminescent triangular and baton indexes, luminescent baton hands, red sweep seconds, aperture for date, large circular case with rotating faceted bezel, crown at 4 o'clock, screw back, case, dial and movement signed, with an integral titanium IWC articulated link bracelet with deployant clasp.

The IWC-Porsche Design 'Ocean' was first launched at the 1983 Basel Fair. Early examples were conceived and designed for the German Navy. Ultimately, the case and movement would be re-designed for civilian use.

This is an unusual wristwatch, partly because of its sleek oversized design and partly because it is made of titanium, a light metal only occasionally used in watches. This is an ideal metal to use in a diving watch, as it does not add much weight to the wrist and it is incredibly non-corrosive, which is helpful in salt water usage.
