This was an ingenious clock movement which had to be wounded just once a week. The name comes from the term Eddomadario, related to the Greek Ebdomee festivity. This celebration took place the seventh day of each month and was held to commemorate Apolos birth. In 1892 the company starts commercializing their watches under the Hebdomas brand name. They became very successful and the firm grew exponentially until 1914, when it was acquired by Schild who changed its name to Schield & Cie. Then, production focused on wrist watches and more brands and sub-brands were created. The patent got disseminated and many watchmaking firms started manufacturing Hebdomas-type movements. After many viccisitudes, today Hebdomas still exists as a prestigious manufacturer of high-end wrist and pocket watches, exclusive for collectors.
