  • Catalogue Essay

    Some of the most important dive watches of the 20th century were introduced in the mid 1950s following World War II, incorporating technological advances developed during the war.

    IWC came to the production of dive watches quite late compared to other brands, releasing its first aptly named ‘Aquatimer’ in 1967. Distinguished for it's clean aesthetics and engineering excellence the model was produced in far fewer examples than competing dive watches, reference 812 AD has grown to be an iconic IWC watch for connoisseurs. The Aquatimer has a modern, sleek appeal with a ‘super compressor’ case that has less bulk compared with other dive watches of the era. A timing ring placed underneath the crystal replaces the outer rotating bezel. This works as a safety mechanism, keeping the bezel from being bumped and accidentally changing the time, as well as giving the watch a flatter profile. Most interestingly, research has shown that dials featuring a fish depiction above the six o'clock signature are part of an extremely small batch of Aquatimers retailed by Chronometrie Beyer in Zürich.

    Further, the in-house caliber 8541 movement features the innovative “Pellaton” winding system, patented by IWC in 1950. This horological innovation uses a bi-directional rotor improved efficiency, giving greater winding power.

    The present IWC Aquatimer from 1967, fitted with its original Gay Frères bracelet, is further preserved in excellent overall condition with strong proportions and a very attractive overall appeal.
