... the Lemania Cal 1277 was produced in fairly small numbers in one year only (1969) and was delivered almost solely to Tissot. It has been described by a couple of the Omega 'authorities' as the 'missing link' between the Lemania Cal 2310 (Omega Cal 321) and the Lemania Cal 1873 (Omega Cal 1863) - the 'Moonwatch' calibres of the same period. Cool pick up!
