Couple of caveats here - the watch might be working well because it is swimming in oil. This can hide a lot of wear and tear, so it is quite possible that once taken apart, a fair amount of damage comes to light. There is only limited availability of spares, and you might end up having to look for a watch on eBay to use for spares ...I'd happily send it to Christian if he was interested in giving me a quote. I have very much enjoyed his forensic recording of services, and would love to see an account of this old watch done like that.
It needs a new hour hand and I would like a new crown and crystal. The original crown was replaced in the sixties with a gold filled non omega one. The gold skin has peeled off that. I still have it, but it is worn. The crystal is a bit battered - not too bad, but it's not great and as I said in a post up above, the hour hand snapped off and I soldered it back on. That was a bizarre happening.I was just setting the time and the hour hand clashed with the minute one. next thing I knew as I spun the crown, the hour hand broke and was dangling like a broken wing by a thread from the boss in the centre. My repair is crude but functional I'm no jeweller so it ain't great. It needs a new hand or more likely a set of hands. I don't suppose you can get them singly. The hand are solid gold as is the rest of the case (18ct).
If you let me know the case number (and if you have it, the calibre number), I can check if I can get some hands for it. Let's first see what is available in terms of spares.
Also, there is the danger that oil will get onto the dial during transport. In the best case, that leaves ugly spots on the dial, and, in the worst case, it dissolves parts of it.
Let me have the case number if you have it and we'll take it from there.
