Abstract
The chronometer comprises a face (11) having a first sector (14) which bears reference marks (12A) and a second sector (15) bearing reference marks (12B). A single hand is designed to move at a first speed between the starting point M of reference marks (12A) and the final point 30 of these reference marks and at a second speed between the starting point 30 of reference marks (12B) and the final point 0 of these reference marks. The displacement of the hand over the first sector lasts exactly nine minutes and thirty seconds. The displacement of the hand over the second sector lasts thirty seconds. This chronometer is specially designed to control the preparation time preceding the start of regattas.
