The origin of "Geneve Line"
Since 1930s, Omega has been the ever victorious army of all the Observatory accuracy trials and the watchmaker, Alfred Jaccard, played a very important role. In the 1929, A. Jaccard joined Omega and dedicated the chronography adjustment work. He helped Omega to obtain the first price immediately in Kew Teddington and Geneva Observatory in 1930 and 1931.
The key is that the Cal. 47.7, adjusted by A. Jaccard, gained the first price continuously of the Kew Teddington in 1933 and 1936. And the record in 1936 (97.8 out of 100) has not been broken until 1965.
In the 1939, the Omega 30mm self-winding movement was produced. After been adjusted by A. Jaccard, this movement won the first price immediately of the Kew Teddington Observatory in 1940. In 1943, the first rose gold-plated Cal.30 T2 was produced and A. Jaccard gained the first price of Geneva Observatory with the 30mm movement. In 1947, the 30mm Tourbillon Cal. 301, specially designed for the observatory trials, was introduced and won the first price of the Geneva observatory trials in the 1950 after adjusted by A. Jaccard. After continuously won the first price of Geneva Observatory in 1951 and 1952, A. Jaccard passed away in 1953.
Omega established its own workshop in Geneva, and the famous 30mm movement is produced in there. To continue A. Jaccard’s traditional spirit in Omega and commemorate the new Geneve stronghold, Omega published Geneve series wrist watch in 1953. The first Geneve product is equipped with 30mm movement. With the expanding of Geneve Line’s product range, they added Ladymatic, Seamaster Geneve, chronostop and some other products. Especially the unique design, reasonable price and high quality of "Dynamic" series, published in 1967 targeting on the young people market, made the capacity of Geneve Line product in 1970 as much as 60%.
In the 1970s, the quartz watch started being popular. Omega closed the Geneve workshop in 1972. And under the shock of Quartz watches, in 1974, Omega's "Geneve Line" was facing the significant market downturn. Some product of the Geneve Line was stopped being produced or merged into other product lines (such as Seamaster line or DE Ville). Until 1979, Omega fully stopped the production of "Geneve Line".
