Yeah it’s possible. Your PO? If it’s running strong I probably wouldn’t worry about it. If it starts running abnormally to its baseline it’s time. One good thing about co axials vs a Swiss lever is they’re not as dependent on pallet jewel lube to maintain accuracy. Downside is I’ve seen some worn escape wheels but what else will run for decades straight without wearing a few parts. In the scheme of things a hundred dollars or so in parts for years of service is worth it.
The thing with mass repair/production is they will often just regulate the watch to run within spec. Seiko does this, well everyone really. Instead of, in their eyes, wasting the time to get it running as perfectly as it can. Positive side to free sprung balances is that they can be regulated mathematically. Meaning there’s a direct output in seconds to the fractions of a turn to the weights on the balance wheel. So getting a free sprung balance to run perfectly is a little more straightforward than traditional regulating pins which are basically trial and error. So if Omegas repair does you dirty on the regulation a local watch maker could give you more personalized service with a simple regulation with Omega doing the full overhaul. Phew probably TMI, sometimes my tism gets the best of me.
