I think this is a very attractive, vintage watch, and having never seen one before I am hoping some of the Zenith folks here can give me their opinion on this particular piece and this reference in general and some idea of value The seller identifies it as a Movement/Caliber 2532 and when queried on how it is keeping time he responded by saying, "The zenith was at +4 to +7 a day after service in February. I’ll put it in the timegrapher today and send you a picture" ( see first picture below ) Plexiglass Crystal Thanks.
