Renaissance of the international chronometry competition

In 2009, the Museum of Watchmaking in Le Locle set up the first chronometry competition for over thirty years in the direct tradition of the old competitions of Swiss or English observatories. The timepieces entered for the competition underwent 45 days of testing spread over three sessions, conducted by the COSC laboratory, the Besançon observatory and then again by COSC. The three wrist chronometers which ranked top of the 2009 chronometry competition placed the bar very high, reaching scores of more than 900 points out of 1000.
