518 minutes
The 518-minute timer counts down exactly to seconds and shows how much time is left before the interval ends. Start, pause and reset, all controls, are in one place. The end of the countdown is indicated by an audible signal, which can be configured or disabled in a separate settings menu. The time converter built into the timer interface automatically converts 518 minutes to seconds and hours.
