I posted this on the Omega forum but hope to get some more replies here. What I do know is that this is a 100th second counter, probably from the 1960s. The AD that sold it was Prestons in Bolton, England, an Omega dealer that is still an AD today. I believe is that this was used in the Paxton diesel train engine factory. Anybody have some more information about this model specifically? I know valuations aren't favored here, but if anybody has any ballpark guesses at all you can p.m. me and it would be appreciated. I want to sell it but a local antique guy / watch collector told me it was basically worthless.
Thanks for your help!
