Aquatimer

A rare vintage diving wristwatch with date and original box - this is one of the first Aquatimer models

Sold

IWC was a little later than other brands in developing diver’s watches and introduced the Aquatimer reference 812AD, resp. 1812 in 1967.
It features two crowns, where the lower one is used for manually setting the time and the upper crown operates the inside stop watch bezel to set the diving time. This crown is positioned directly on the edge of the dial under the crystal to make accidental readjustment during the dive impossible. The case is waterproof to a depth of 200 m; the heavy case back possesses an inner super compressor area, which increases watertightness in greater depth and compresses it further under higher pressure. Inside the watch beats the proprietary IWC calibre 8541 with the legendary Pellaton winding system that was also used for the Ingenieur range.
This timepiece dating from 1967 is one of the very first Aquatimer watches. Despite some slight traces of age, the watch is in excellent condition with luminous indexes and hands that have acquired a charming patina – a must-have for every fan of vintage timepieces.
