Consigned by a Swiss engineer that worked since the end of the 1960’s at Omega in R&D called SSIH, he worked at developing the first quartz wristwatches developed in Switzerland. During the seventies, the technology of integrated circuits featuring quartz with vibrating movements or not and its displays were advancing very rapidly making certain projects in development phases already absolete. Conceived in collaboration with the Battelle institute, the Marine chronometer became in 1974 the most precise wristwatch in the world.

Interestingly this example features a prototype movement number characterised by the four zeros in front of the movement number as well as a prototype case featuring a bevel on each sides designed to minimise wear on the shirts that was later abandoned on the production model. A rare piece that reflects the technological advances made by the watch industry in the quartz age.
