Dear Forum I found this Omega watch moonphase ref. RO33 from 1955 in a well known site of second hand wristwatches. Unfortunately I can't check personally the watch and i have can't add the pics. Pics are available at the page: https://www.chrono24.it/omega/moonphase--id4964534.htm What's your impression? I didn't found the reference on the Omega Official page. What could be the price? Thank you very much for your help. dan02
Or you change the language to English , seller appears to be in Leicestershire. There are no real close ups of the watch and that would concern me
