Hey all, new guy here and bout a watch. Ref # on case back is marked 166.091 searched omega website and came back to be a 1971 Seamaster 200. What exactly do i have, google didnt come up with much. It runs when i hold it in certain positions, but it is missing the winding crown? The internal parts look to be in great shape and do say Omega, so its not a replica. So what do i have and whats it worth? Also it does have the original stainless band.
As you already found out, you have a 166.091 Omega Seamaster 200. It appears to be missing the crown, however I think there is something wrong with the case tube. I believe the original crown was a screw-in crown, which would require a threaded tube. So there is some sort of problem with the tube that likely requires a visit to a watchmaker. From the sound of it the watch needs a service as well.
Difficult to say on this one, since there are not many examples that sold recently. You can try and use the far more popular 166.0177 as a reference. A 166.0177 sells for an average of 2000US$ in NOS condition (of course many of these are watchco). So you are looking at a less popular model in rough condition and unknown service requirements. Basically a project watch. Your best bet, IMO is to list on eBAY and see what it brings.
