Dear watch enthousiasts, I always believed that the Lemania 2310/2320 (27 chro C12) served as the base movement for the Omega c.321 Recently I saw the Lemania 2520 advertised as the base for the Omega c.321 (in an add for a Meylan chronograph) I cannot find a lot about the Lemania 2520, can someone shed some light on this? TIA! Kind regards, Bart
