Guba 25

Description

The Guba 25 was launched between 1953 and 1957. It was completely unmarked, but could be identified thanks to the scraching of a watchmaker on the dial plate and the Flume Werksucher from 1957.

It uses seventeen jewels, among them one cap jewel on the dial side. The gold-tone nickel screw balance is not shock protected. The size of the movement is the formerly common 5 3/4 x 8 3/4 lignes.

The Guba 25 was made in different versions and probably over a longer time.
