This is the only watch I wear. Why? Because it has the functionality I need. I am a heavy computer user & suffer from severe eye strain. I bought this watch because of the 'timer' functionality.

You can choose a number of preset timers & it will actually continuously loop if you want. I have it preset to 25 minutes so that an alarm sounds every 25 minutes which reminds me to stand-up, relax my eyes & refocus.

Additionally, the watch has an alarm, stopwatch, a setting for interval training & a world clock. For $20, you can't go wrong.
