Good afternoon. I would like to present to you a rare wristwatch, Omega Constellation Chronometer Kal.1111,Referenz: 1448/431.1 Stahl/18K Gold. The watch does not look bad, although there are a few scratches on the dial. The watch winds up and goes, but needs service (not always showing the exact time) and as it seemed to me tmeyu. The time translates, the calendar works. Any questions, please ask.
