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!
Last year I published an article on the long and complicated story of Hebdomas, the 8-day watch with the exposed balance wheel. As I discussed then, the watch dates all the way back to 1889 and remains in production to this day, a remarkably long life for a fussy old fashioned design! But I did not then have access to some of the sources of information that inform my research today, and a few readers pointed out some areas I missed. Today I am diving deep into the origins of the Hebdomas, the inventor Irénée Aubry, the watchmaker Arthur Graizely, and the industrialist Otto Schild.
Spend some time looking at old watches and you’re bound to stumble across an unusual watch with an off-center dial, fancy exposed balance, and 8-day power reserve. The dial will likely say “Hebdomas” and “8 Jours” and not much more. Is this some exotic high-end watch or a mass-market pretender? That’s the story I’m telling today!
