Omega connie c-shape buy or not ?

hello guys, lets start from the beginning.All start with the c-shape connie thread on this forum and i really liked the beauty of this kind of case .I found recently one on a local site and i was wondering if all its good .IMO its a not a redial but i am not expert, the crown i think its not correct for this ref ( i dont have movement pics but i think its a 168.017 with 564 movement ),at the minute hand the egde lume is off, the dial has a yellow tone from the age ,it was a big problem? The seller says that is recently serviced. PRICE 750 euros but negοtiable.Thank you very much !

Also dont beleive the seller about a recent service, as it looks To me Like there are bits of lume all over the dial

Thank you for your advice,yea in this game patient is the key,
