Currently looking at this, any reason not to? There are a full set of photos including cards and all boxes. Many thanks for responses in advance.
Apparently it was NOS from Hong Kong with the warranty card stamped 2020? Potentially get it for £3600.
I've seen them without the markings on the el's. On this model only. Like 2015ish ones. I think they are just marking them on the clasp and arrows on the removable links... maybe the # is on the inside towards watch?
O Omega used to put the red seal on the caseback from the factory. If still intact, it means the caseback hasn't been opened since new. This also means the watch hasn't had a service since new.
