I think a lot of the members here have follow the Christie's auction last December and maybe remember this Omega Speedmaster 50. The realized price was $25k. I have such a dial and would like to know what you would do with it. Keep it in the drawer, build up a watch with or sell it, if sell how much is it worth ? I dont know what I should do with.....
Is that a 176.0012 dial variant (service) or a prototype dial. The watch case at Christies was the prototype not the dial I thought. I admit the minute markers font esp on the 25 and 35 seems unique to the Christies auction and yours.
I think the case is nothing special as some Tissot Seastar Cal. 1340 modells are using this case also. Maybe I'm blind but I dont see the difference you mentioned
This is a Mark 4.5 dial, and it is different from the Christie's dial, most noticeably the 55 cut off and the tritium "T"'s on both sides of the "SWISS MADE".
