THE GENEVA CHRONOMETRIC OBSERVATORY: A KEY PLAYER IN HOROLOGICAL PRECISION
True to its educational vocation, Horopedia is releasing a new film dedicated to the Geneva Chronometric Observatory. This original content offers an immersion into a central organization in the evaluation and certification of horological precision.
Now managed by the Timelab Foundation, the Geneva Chronometric Observatory is a major player in horological certification in Switzerland. It notably issues the “certified Chronometer” certificates according to the ISO 3159 standard and the OC+ label.
The OC+ label is a demanding certification, exclusively reserved for Swiss watches, that goes beyond traditional standards. Unlike the ISO 3159 standard, which tests movements alone, the OC+ protocol evaluates fully assembled watches, under conditions close to real-world use. Over a period of 21 days, the pieces are subjected to a series of rigorous tests covering in particular:
- chronometric precision
- Power reserve
- water resistance
- resistance to magnetic fields
The ISO 3159 standard, for its part, has been an international reference since 1976. It defines the precision criteria for mechanical watches, tested over 15 days in different positions and at several temperatures, with a required average Daily rate of between –4 and +6 seconds per day.
Through these protocols, the film highlights the constant quest for precision in horology, as well as its evolution over Time.

ABOUT HOROPEDIA
The Horopedia Foundation was created in February 2023 and received public interest status. The Foundation’s Board is composed of Philippe Dufour (Chairman), Dr. Helmut Crott, André Colard and Marc André Deschoux.
The Foundation manages Horopedia.org, the first online video encyclopedia on watchmaking. The platform was launched in 2022 and quickly received unanimous support within the community.
To date, more than 100 multilingual documentary films about museums, watchmaking schools, watchmaking tools and components, and the mechanical principles behind how they work can be found on Horopedia.org. To strengthen its educational mission, the platform also incorporates visual teaching aids to facilitate a better understanding of the information provided. The site offers nearly 1000 pages with detailed definitions of watchmaking terms and historical anecdotes about significant horological inventions.
Horopedia.org meticulously covers all aspects of the fascinating watchmaking industry in French, English, and German. It offers detailed definitions of tools and complications, 3D images of movements, and in-depth video explanations on the production of components, their history, and their functions in a watch. A dedicated section of the site lists horological institutions, including schools and museums in Switzerland and around the world.
More recently, the Foundation unveiled its ambitious project: the Maison des Arts & de la Culture Horlogère (MACH). More than a museum, the MACH will be a vibrant space for exhibition, transmission, and exchange around the art of watchmaking. Located in the heart of the Quartier des Banques, this house of 1,250 m² will span four floors, offering didactic, thematic, and chronological exhibitions, complemented by a space dedicated to temporary exhibitions. Visitors will also be able to enjoy a shop, an auditorium, and various interactive spaces designed to spark curiosity and encourage discovery. Open and lively, the MACH aims to become the crossroads of watchmaking in Geneva.
