Abstract
Electronic watch for yacht races capable of being used for effecting a countdown from a warning signal, having sufficient possibilities of control and possessing a clear and easily identifiable display with regard to the time remaining until the starting signal of the race. The watch comprises control means which permit, by means of some of the electronic circuits incorporated in the intergrated circuit of the watch, starting and stopping of the countdown of at least one of the time sequences preceding the start of a race, correcting the display of at least one of the time sequences, and delaying the start of at least one of the time sequences of the watch, the start of the time sequences being announced by signals external to the watch.
