History of Lemania / Omega links  

The strong bonds between Lemania and Omega date from the 20’s : during the economical crisis of the period Omega and Tissot signed an agreement (1925) before merging in the same group : SSIH (Socièté Suisse pour L’Industrie Horlogère) , two years later Lemania joined the ossociation of companies.

Therefore the groupment between Omega and Lemania dated by far before the aquisition of Omega and Lemania by the Swatch Group.

 

Lemania develloped a large number of movement for Omega , the probably most known is the Omega caliber 861 which power the Omega Speedmaster since 1969 (today the movement number changed for 1861but it is basicaly the same movement)

 

In the erly 70’s Lemania start to work on an automatic chronograph movement creating the ancestor of the 5100 : the caliber 1340 (Cal Omega 1040 according to their numbering system) .

The 5100 can be concidered as a simplified version of the 1340 adding features (24 hours register) and simplifying the manufacturing process (pilar construction and use of platic parts)

 

The first Omega to use the Lemania 5100 was introduced on the market in 1974 , Omega use their own numbering system to designate the Lemania 5100 : Omega 1045.

The finish of the movement is specific to Omega and stamped with their name

A number of Omega speedmaster have been produced with this movement from 1974 up to 1987. Unfortunatly it seems nearly impossible that Omega will ever produce any watches with this movement again because production has ceased

 

The Omega Speedmasters fitted with 1045 movement
