Works like a normal stopwatch. Has 2 time zones, an alarm and a timer function. This is really annoying just that when using the timer function the clock annoying, makes confusing beeper! This begins at 2 minutes before it rings. Since it beeps for the first time, then when only one minute there is time, then 30 seconds and then the last 10 seconds every second. That I do not need, and it confused with total! I just need a timer feature that really piespst when the time is up, but I have to think again, what was the beep every time. So the timer function, I do not use to. Stopwatch is it quite normal.
