Omega SA
In 1978-79, a collaboration starts between Bouchet-Lassale SA and Omega SA, through Lemania-Lugrin SA, L’Orient, which were both units of the SSIH Group (Société Suisse pour l’Industrie Horlogère, which does not exist anymore today). So, Lemania–Lugrin SA built calibres 1200 and 2000, Omega owning a non-exclusive license for the production and the sale of those movements.
