545 hours
A 545-hour timer counts down the set interval to within a second and helps you conveniently control the time. Thanks to the built-in converter, you will immediately see the duration of 545 hours in days and minutes. Control is implemented using simple buttons that allow you to quickly start, stop or reset the timer. The sound notification is adjustable — you can select the signal or turn it off completely.
