Caliber Commentary:

Orient isn’t the most organized when it comes to model names, reference numbers, and caliber numbers. There are some chances of caliber confusion with the caliber number being F7M65, but the model being referred to as the M45 F7. Some of Orient’s marketing material calls it the “M45 F7 Mechanical Moon Phase” being powered by the “Orient Star in-house caliber F7M65”. Maybe it would have made more sense to choose numbers that match, such as calling the model the M65 or the caliber the F7M45.
