Hi guys Maybe a good place to ask regarding a cal. 321 Speedmaster which I'm looking to buy. What do you think about the watch? Anything weird? It's a 145.012, Cal. 361 from 1968. I want to avoid making a mistake, as it will be my first Speedmaster I'm not an expert and thankful for any Inputs. According to the seller the watch is all original except that the Bezel was replaced and the caseback was replaced. The watch is in working condition, but needs a service as the reset of the 12h Display is not always working. As well the back shows slight traces of corrosion. As I'm not in a hurry and don't want to overpay; What do you think would be an appropriate Price range for such a watch in that condition? As well, what does a proper Service at a Omega Boutique costs (as I will have to include this Costs as well in my decision making). Still quite new to the Forum, appreciate the help ! Thx.
