YACHT TIMER MODE

uYacht timer combines the functions of a count down timer and a stop watch that starts operating automatically when the timer finishes counting down. This function is particularly useful in yacht racing.

Yacht timer operation

There are 3 pre-set yachting timer modes: 5-minute, 6-minute and 10-minute timers.

Upon activating the yacht timer function, the selected yacht timer starts counting down in 1-second increments.

The remaining time is indicated by the center hand and the two hands of the small watch, which turn counterclockwise while the yacht timer is counting down.

When the yacht timer finishes counting down, the beep will sound indicating that time is up and the measurement is automatically switched to the stopwatch.

The stopwatch can measure 12 hours in 1-second increments. When the measurement reaches 12 hours, the stopwatch automatically stops.
