Hebdomas Watch Company
Hebdomas was founded in 1888 by Iréné Aubry in La Chaux-de-Fonds, Switzerland. The firm established both its notoriety and market position by uniquely producing 8 day time-keepers; that is, watches that could run for a full eight days on a single winding.

The brand name itself was inspiredby the word Hebdomandaire, an ancient Greek festival which occurred on the seventh day of each month in celebration of the God Apollo’s birth.

From the onset, Hebdomas enjoyed considerable commercial success. Justified by the above average production costs inherent to an eight day movement, their watches were expensive and sold by leading prestigious watch shops.

Their very distinctive look with apparent balance wheel and eccentric hands offered Hebdomas enormous recognition value, a design which the firm would maintain for its wristwatches as well, with the exception of a very small number of rare traditional looking wristwatches, especially for use in the trenches of WWI.

In fact, even the apparent balance wheel wristwatch models are relatively rare. Most examples of vintage Hebdomas watches seen in collections today are pocket watches, because the Company only briefly marketed wristwatches from 1913 until the very early 1920s.

Inaterestingly, while Hebdomas manufactured it’s pocket watches in-house, they chose to entrust their wristwatch production to Anton Schild’s famous Grenchen, Switzerland firm A. Schild. At the time, Schild already had established himself as a leading pioneer in wristwatch movement production. Ironically, it also was A. Schild who hardly more than a decade later would develop and manufacture a product which spelled the 8 day watch’s demise: The John Harwood automatic wristwatch!
