As others have said, I would be very wary of the proposed dial work. The pricing for service is pretty much in line with most reputable watchmakers, and although some may disagree, you get what you pay for when getting a watch serviced. Parts for this caliber are going up all the time, and Omega has been jacking up the price of parts in a very big way the last couple of years. Some parts are going up in price 4X overnight...and the "reversing wheel" (a.k.a. winding wheel) on this movement is quite expensive - $104 the last time I bought them. And now Omega will only sell them to you on an exchange basis, so I will incur the added costs of having to send the old wheels back to them when I want a new wheel...
As for this being "recently serviced" well you should always take that with a large grain of salt. I received a 321 Speedmaster recently from someone who bought it "recently serviced" by a watchmaker who doesn't have "outrageous pricing" as some would say. The watch arrives with poor balance amplitudes, worn parts inside, and although the train wheels had fresh oil, when I opened the mainspring barrel, this is what I found inside the barrel cover:
And this was the inside of the barrel drum:
And this is the mainspring - note the black marks along the spring. This is evidence of wear on the spring itself, and if you pull it through your fingers you can feel that it's "wavy" along the entire length:
So unless a vendor is providing you written proof of a proper service, done by a reputable service provider, you should always assume it will need a full service.
