  • Catalogue Essay

    Released in 1967 in a far more limited numbers than other sport watches, reference 1816 is a historically interesting timepiece representing IWC 's entry in the submersible world.

    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. Furthermore, the in-house caliber 8541B 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. Reference 1816 features a cushion-shaped case with luminous hands and hour markers rendering the dial easy-to-read and extremely recognisable from vintage diver's watch collector. Offered overall in great condition, the presented lot is an interesting and early diver's watch from IWC and definitely a must-have for collectors new and experienced, alike.
