Genuine Omega motor - ref  1320-9100 . This came out of a brand new old stock watch with caliber 1320 and also fits the analogue part of 1976 Omega Chrono-quartz analogue/digital watches . 

The watch it came out of was brand new but with battery leak into the microchip . My watch maker has tested and found this motor to be in FULLY WORKING ORDER and perfect condition . It has been secretly marked so please do not attempt to swap it for a damaged non working item . No longer available from Omega now and a very rare part indeed that is the difference between your watch not working and worthless or working and loved again . It will make your non working watch very valuable once more
