Amazing and very rare Longines 13ZN with stunning black dial from 1941. This example is one of the rarest 13ZN references as it's an early version with pump pushers and snap case. The step case is ref 3870 and is still unpolished, amazing after 80 years! It measures 34mm excl crown. The original dial is super rare and not often seen (mostly silver). It's got small subdials and gilt print with gold hands which is a stunning combination. It aged slighty around the edges which is consistent with the unpolished snap case. The movement is very clean and was serviced and the flyback is functioning perfectly. It comes with a Longines extract and attached is a brown strap from the 1940's! True collectors grail which suits every wrist.
