Tissot pointer date

In the early 1940’ies Tissot and Omega had been working closely together on making high-end watches since the companies merged in early 1930. The calibre 27 stands as the legacy of the two companies early years in collaboration. But was only very few people know is that the calibre 27 actually was the true legacy of a company named Lemania whom merged with Tissot and Omega in 1932.

Early on Tissot & Omega adopted Lemania’s calibre 27. Omega and Tissot used the movement until the beginning late 1950’ies. Though the most used of Lemania’s calibres was the CH 27 a calibre that Omega used in one of their mostly popular chronographs – the Omega Speedmaster – which was the official time keeper at Olympic games in 1956 and made summited the moon with NASA in 1969. Omega was also chosen as official time keeper at Olympic games in 1932 – a spot in the sun achived with the merge between Tissot, Omega and Lemania in 1933 and the more basic caliber 27.

The base calibre 27 was from the mid 1930 until the mid 1950’ies placed in the most desirable of Tissot watches. Actually Tissot refined Lemania’s calibre 27 into a family of calibres.  Which started which numbers ran from calibre 27-1 and ended with caliber 27-7.
