Reasons to Bid

This IWC Aquatimer Supercompressor Ref. 1812 offers collectors a chance to own one of the most iconic dive-watch designs from the 1960s and 1970s. The model features the famous EPSA Supercompressor case with twin crowns and an internal rotating bezel, a construction known for its technical reliability and importance in dive-watch history. The 37 mm stainless-steel case, clean black-and-silver dial, and bold luminous markers reflect IWC’s functional approach to underwater tool watches. Powered by a robust automatic Caliber 8541, the watch delivers dependable performance while preserving all the charm of a true vintage diver. Well-preserved examples of the Ref. 1812 have become increasingly difficult to find, making this piece a rare opportunity for collectors seeking a historically important and highly wearable vintage Aquatimer.
