This Omega watch works when wound. it was purchased around 70s from the official Omega dealership.
it has the original bracelet.
it is not clear when whether it has been fixed once in the official dealership or it has never been fixed.
it has never been cleaned, in order not to lose the authenticity that someone could seek in a watch like this. The crystal has been only polished and replaced.
unfortunately, no authenticity documents are available, as they have been lost through the decades.
the Model is either 145.022 or 012, or 105.012. If someone expert is interested in can provide more photos which could indicate some more data.
Was given via my grandfather.
