can across this today on a local auction site. To me it looks authentic but in no expert . The movement has a start stop problem nothing that would stop be from buying . What's your thought Thanks Steve
Its also listed on eBAY with a BIN of 1250 GBP. I would not be too concerned with the need for service. As I mentioned in a previous post, 2990 Seamasters can be found in the below 500$ range. So you are basically looking at an additional 1500$ for the hands and "Ranchero" print on the dial. Might be worth it to someone..
Never seen those markers, they usually look like this one: https://omegaforums.net/threads/omega-ranchero-30mm-2990-1-cal-267-1950s.4574/
