Berna is perhaps the greatest forgotten watch brand of Saint-Imier, and the Droz factory on Marronniers 20 is just as unknown. But it was the first large and modern factory in Saint-Imier and should be remembered along with the waterproof pocket watches and industrial control stopwatches produced there. Equally important is the involvement of industry pioneers Alcide Droz, Ernest Degoumois, and the Jeanneret family, and the later integration of Berna with Leonidas.
This is the story of a simple postcard that compelled me along a deep and complicated path of research and discovery! Titled Les Grandes Fabriques d’Horlogerie de St Imier, the historic 1900 postcard shows “the five great watchmaking factories” of this small town. Over the past year, I’ve been learning more about these companies, in which the Jeanneret family was intimately involved, including Excelsior Park, Francillon’s Longines, Fritz Moeri’s Moeris, Droz & Cie and Ernest Degoumois’s Montres Berna, Ferdinand Bourquin’s Leonidas, and more. This is the first in a series of posts on the great factories found in these engravings!
