Omega? I think you mean Seiko.
Seiko has always been proprietary with parts. I’m not if there are any factory authorized Seiko service anymore. Only the national service centers at this point and even these can’t service every model.
I’ve been told that even
Seiko USA is no longer servicing cal. 6138 and 6139 anymore due to lack of parts. Maybe Seiko Japan can handle it, but if so, it’s not going to be cheap or quick.
Crystals are available generically, but the other parts are going to be problematic. While parts may be available on eBay, you’ll need to work with a patient watchmaker knowing that some parts will take extensive searching.
Hope this helps,
