This Omega Marine CK 679 from 1939 is one of the earliest purpose-built waterproof wristwatches. It features the patented double-case construction in stainless steel, designed to protect the movement from water ingress. The original dial shows Arabic numerals with blued steel hands, housed beneath a rectangular crystal. The watch is fitted to a later leather strap.
Condition
Case: Stainless steel case with patented double-case construction; light wear consistent with age.
Dial: Original dial with even patina; Arabic numerals intact, blued steel hands present.
Crystal: Original rectangular crystal with light marks.
Strap: Later leather strap in good condition.
Movement: Omega Cal. 194 manual wind, inspected and running.
Launched in 1932, the Omega Marine was the world’s first commercially available dive watch. Its double-case design, tested in Lake Geneva to 73 metres and certified by the Société Suisse de Chronométrie in 1936, represented a breakthrough in water resistance and marked a turning point in wristwatch design. The CK 679 remains a highly collectible reference, as few examples of the model survive today.
