If we are talking about and Omega Connie- here is the link to the mothership. I was quite pleased with the job the did for me on my Seam aster 50thAanv GMT after the Watch Dr could not get it to hold time. I appreciated his candor and suggestion to go to Omega Inc.
Cost was about 600ish with shipping and tax. They paid for the inbound to assess and confirm pricing for the work, I paid for the return. The replaced springs, hands, misc. parts and gave it a polish job that had it looking brand new. 2x the price of the Watch Dr. 1/2 of a similar treatment to my buddies Rolex by their mothership. 2 yr warranty on the work which equaled the warrant under which the watch was sold to me 10+ years ago.
I have another buddy who had his Speedy tuned up by Omega and was quite happy. In the end, it had to go back to the motherland but they stuck by their quoted price.
Given your watch's origin story, I would be highly inclined to send it to Omega.
