Lemania 2310
In the 1940's, Lemania and Omega worked together on a project called "27 CHRO C12" to develop a 27 mm diameter chronograph with a 12-hour register. Lead by Albert Piguet and Jaques Reymond, this project resulted in the 1942 launch of the Lemania 2310, called Calibre 321 by Omega.
Calibres 2310 and 2320 are used as the ebauche and base design for the many prized chronograph movements from names like Patek Philippe, Vacheron Constantin, Breguet, and Roger Dubuis. It is widely regarded as one of the finest such movement designs in history.

The watches and watch movement manufacture Lemania was founded in 1884 by Alfred Lugrin (1858-1920), who had acquired his expertise as a laborer at Jaeger-LeCoultre in Le Sentier. Because of the outstanding quality of his watch movements Lugrin received top awards and gold medals at exhibitions in 1906 in Milan and in 1914 in Bern. From the beginning he had specialized in the production of chronographs, stopwatches and repeaters.
The Lemania Calibre 1873 (Omega Calibre 861) became particularly famous with the Omega Speedmaster, which in 1962 was selected by NASA for manned space flights and on 21 July 1969 accompanied Neil Armstrong's first steps on the moon. Lemania then worked with Omega to develop a high-quality cam switching automatic chronograph, launching their Cal. 1340 in 1972. This was followed by the 1974 introduction of Cal. 5100.
Breguet was acquired by the Swatch Group in 1999. Over the next decade, the Lemania name was retired, with the company now called Manufacture Breguet. The company primarily produces calibres for Breguet, but many of its products are also used by other Swatch Group brands. Although Lemania's ownership by SSIH brought it very close to ASUAG, Ebauches SA, and SMH/Swatch Group, it was never part of this conglomerate or of ETA, their movement manufacturer.
Lemania has produced many famous movements, including the following:
