You can set the countdown start time within a range of one minute to 30 minutes. The watch has a preset “reset time” of five minutes. Pressing a button resets the countdown start time to five minutes. A progress beeper keeps you informed of the progress of the countdown. An alarm sounds when the timer reaches zero, and a count up elapsed time operation starts. All of this makes the countdown timer a useful tool for yacht racing.
