You’d have to total the time it takes to fabricate each of the individual parts, adding to that the time taken to assemble those parts into a running watch, then add to that the time taken doing the final adjusting and testing involved, before the watch can be said to be finished. Where you’d find an answer to your question, I have no idea. I once read that one of the U S watch companies had a machine that could turn steel wire into 28,000 tiny screws in an 8 hour shift. Likewise, throughout the factory, these parts all being mass produced. I doubt Omega could even give you a precise answer.
