The present watch is a very well preserved example of Omega Marine from the mid-1930s, equipped with the 19.4 T2 caliber.
The reference 679 is characterized by its specific case without lugs (the next generation, reference 680, will have normal lugs).

In 1932 Omega introduced a waterproof wristwatch called the Omega Marine, reference number 679. The Omega Marine was the first dive watch commercially available to civilians, the first watch specifically tested and qualified for diving.
The watch movement, dial, and hands were encased in a rectangular section interior case. This interior case had a shoulder at the end with a groove which contained a cork gasket. The interior case slide into a rectangular outer case, the end of which contacted the gasket in the shoulder of the interior case, creating a water tight seal. A spring clip on the back of the outer case held the two parts together. The clip provide the initial seal between the inner case, the gasket, the outer case, and as the watch submerges, the air pressure inside the case remain constant while the water pressure outside the watch increased,
compressing the two parts of the case even more firmly, increasing the water tightness.
The Marine was at first fitted with the manual winding calibre 19.4 T1, but later with the improved 19.4 T2, created in 1935. It is interesting to note that outer case had a sapphire Crystal. Sapphire was used because it was much stronger than glass and this was probably one of the very first use of sapphire on a watch.
In 1848, Louis Brandt founded a company in La Chaux-de-Fonds which would become Omega. In the 1880s, the Louis Brandt & Fils company moved to its current site in Bienne and in 1894 the caliber Omega was created, which would give its name to the company. Renowned for its precise, innovative and affordable watches, it became the largest supplier of watches to the British Army during World War II. It also became the first company to time the Olympic Games in 1932. Among its range of numerous professional watches, the Speedmaster became the first watch worn on the moon in 1969.
