Cocktail watches are very interesting as they don't always have a reference or a specific recurrence. This watch is looking fabulous and is quite unique in its design. The original Cal 282 movement has been changed for a newer, more reliable cal. 1400 sometime in its lifetime. The case looks unpolished.
