Hello, new to this forum. I have been collecting some vintage Omegas for the last year or so. My criteria when buying is purely aesthetical. I picked this up a couple of weeks ago. It has no external case markings. The hour hand appears to have a transparent quality as you can see the letter 'A' of Omega through the hand. I have trawled the official Omega archive, my next stop is to take it to a jeweler who can take the back off for me to see if it is marked with a serial number inside. It's a very pretty watch, does anyone recognise it? Many thanks in advance.
