1935 rare Omega-Tissot Monopulsante Porcelain dial, manual winding Chronograph cal. 33.3, 37.4mm. case.
The Omega cal. 33.3 chronograph series, which is considered to be a forerunner of the Speedmaster, is one of the most sought-after chronographs by Omega-Tissot. It is said that only 14,000 movements were produced for 20 years.
Omega and Tissot have always been two different companies, despite marriages between the two families.
After the crisis of 1929 the market for watches collapsed in Europe and the solution found by Omega and Tissot was to unite the capital in a single holding company “SSIH Societe Suisse pour l’Industrie Horlogere”, but maintain separate companies – Omega with medium high market and Tissot with medium market. Now both brands are part of the Swatch group.
