1 Million Chronometers Certified by COSC

More than 1 million chronometers were certified in 2000 by the Official Swiss Chronometer Inspectorate (COSC), according to a report of the Federation of the Swiss Watch Industry. The exact number was 1,032,258, a 9.1% gain over 1999 and a new record. The top five brands with the most certifications, says the Federation's report, were Rolex (635,209), Breitling (148,380), Omega (146,144), Bvlgari (21,345), and Panerai (19,231). "Chronometer" is a designation of very precise accuracy, assigned only to high-quality watch movements tested and certified by the COSC. Each movement is individually tested over several days in different positions and temperatures, and passes only if it shows a loss of less than five seconds per day.
