Quote from official booklet:
Chosen for its exceptional quality by professional navigators. After deciding in 1978 to replace its supply of mechanical chronometers with a timepiece designed for the eighties, the French navy’s Hydrographic and Oceanographic Service (SHOM) contacted various watchmaking firms. The SHOM , situated in Brest, has always been “at the forefront of ocean discovery and service to navigators”. It provides the nautical and aeronautical documents (ocean maps) as well as instruments of navigation, meteorology and oceanography necessary to the operations of the French naval forces.
After a rigorous selection of products, followed by a year of testing at sea under the most stringent conditions, the SHOM’s final choice was a quartz chronometer developed by Omega. A large number of Megaquartz were tested at the SHOM by the Department of Scientific Instruments and Material (verification of precision and temperature stability, mechanical environment tests, resistance to magnetic fields). The report’s conclusion: “no abnormal functioning was observed”.
The Omega Marine Chronometer Megaquartz Calibre 1525 was designed by Henri Schneider. At the time of production, this was the most precise portable autonomous timepiece, second only to an atomic clock. The accuracy is in the 0.01 seconds per day range. Pierre Aubert, the head of the Department of Foreign Affairs for Switzerland used this piece as an official gift for the recipients: King Carl Gustav of Sweden in 1985, President Mitterand of France and King Houssein of Jordan in 1987. It was also chosen by the city of Geneva to present to the Presidents Reagan and Gorbachev during the America-Russian summit in 1985.
