Greetings, knowledgeable Members of this forum! Can some clockwork lore-master help me identify and possibly evaluate this piece? Alas for the time being I haven't opened the case, fearful of scratching it. The back is absolutely plain with no markings. I have no wish to sell it, but I'm curious about its value. I also seek your counsel on the matter of restoration – my plan is to gently clean the digits and hands, and perhaps putting some really thin layer of protective varnish on them to preserve the shine of the copper, and stop at that point leaving the rest as patinated as it is. It is by no means my definite decision, as I suppose it can arouse some controversy here. I am open to all advice and professional suggestions never having owned an Omega before. Thank you in advance, I shall update the post with a picture of the mechanism as soon as I have it opened. EDIT: the sub-second hand is there, only the exposure was 8 seconds and it got blurred. EDIT 03.02.2020: The interior for those starting to read the thread from the beginning.
