Early 1940's Manufacture OMEGA ss 35mm Water Proof Chronograph with famous Cal. 27CHRO12 Rare multicolor scale dial with Lemania Cal. 27CHRO12 from 1942. The multi-colored scale dial with pulsometer (blue), telemeter (black) and snail tachymeter (red) on a silver two-tone base is reminiscent of the 33.3 chronographs of the same era, and the massive 35mm screw-back waterproof case is a wonderful example of a watch from this era, different from later Cal. 321. The 35mm size, multi-colored scales, and the condensed feel of a three-register chronograph stand out.
