My daily driver, so to speak. Not the nicest or most expensive watch i have, but I'm very fond of it. Bought it for a steal, originally assumed it was a replica, but it wasn't. Its been keeping time for 50 years, and I'm making sure it will do so for 50 more. Serviced and refurbished last year. The dial is the only bad part, but that will be sorted this year. You'd be surprised how difficult it is finding dials for these things. You'd think spare parts for Omega watches would be readily available.

I have a 1967 Omega Seamaster. What a great dress watch. I would keep your dial as is. One, it gives it character. Two, it can actually decrease in value by replacing, or even cleaning up the dial.
