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!
