Excellent example of French Zenith production from 1920-1930s. In the beginning of XX century France trade barriers over watch market to protect French watch industry from strong Swiss competition.
That's why in 1921 Zenith installed factory in French watch capital Besançon, producing quality watches for demanding French clientele.
Movement is fully jewelled and features Besançon seal.
The Besançon seal was established in 1929 by the unions of manufacturers of Besançon and Doubs in order to reward the most beautiful timepieces. It certifies superior quality and is incidentally a way of creating a sort of controlled designation of origin.

It was a kind of French answer to Geneve hallmark.
