This triple-date Felsa caliber 693 chronometer movement was found in an 18k moonphase calendar chronometer by Record Watch Co. The movement is signed by Favre-Leuba Chronometer Co.
Although this tuning fork movement was designated by Omega as a caliber 1260, the base movement is an ESA (Ebauches S.A) 9164. The ESA 9164 features a day and date. Caliber ESA 9162 (Omega caliber 1250) has a date only.
