Hello, I bought this Omega to give to my father. It should be a reference 168.017 Caliber 564.Confirm? At the moment I did not open the screw back. Now I would like to bring it back to its ancient glory. But first I would like to have clear ideas on some points: 1) the crown does not report the Omega brand. this is original or has been reassembled? if refit which crown model is correct for this Omega? Measure are 4mm x 2mm. 2) Hands fit . Not seem original. What is your opinion about? Any other suggestion/ info or idea is very appreciated! Thank you in advance! [/IMG]
