Omega Vintage Seamaster authenticity
seamaster - front
I've received a vintage Omega Seamaster as a gift. The strap is new but I'd like to confirm the authenticity of the body as I'm not sure if it's 100% real, fake, a refurb or franken-watch!
If you couId share anything on this I'd really appreciate it :) I have attached some images that will hopefully be of use (sorry if some are a touch out of focus). The back is very plain, with the word 'Waterproof' around the bottom and 'Seamaster' along the top.
Many thanks, and all the best,
