Aquatimer Reference 816 AD
One year after the original Aquatimer, the Reference 816 was born. Of course it was highly water-resistant. But it also featured an eye-catching red dial, and its indexes and baton hands were inlaid with tritium for easy legibility even at the darkest depths.
The Ocean 2000 (Ref. 3500)
A celebrated design by F.A. Porsche, a revolutionary titanium case, and water-resistant to no less than 2000 meters, this icon cemented IWC’s reputation as a maker of the world’s best dive watches. How good was it? Good enough for mine clearance divers of the German Navy. Read more about an extraordinary collection of Ocean Bund watches.
Deep One (Ref. 3257) and Deep Two (Ref. 3547)
The GST Deep One diving watch was brought to life in 1999. Reference 3527 featured a mechanical depth gauge, which was the result of an incredibly clever design and relentless engineering. Ten years later it was followed by the Aquatimer Deep Two, Reference 3547, which was even more water-resistant, and gained the ability to record maximum depth reached during a dive.
