I have own several referee watches for soccer and this is by far one of the nicest one. It has so many features and once you become familiar with them (read the manual) they are very handy and easy to set. The one that I like the best is being to increment the  time intervals from 10min - 12min - 15min -20min - 25min - 30min - 35 min - 40 min -45 min with a touch of a button and repeat the time. I will report later how it holds up after a year.
