If you're a sound sleeper this watch might not do the trick, but for me it does a great job of letting me know when to get up without disturbing my wife. It also has no less than EIGHT other alarms, which means that I can set silent alarms throughout the day (get up and stretch, go to lunch, get ready to go home, go home...).

You can also set it to vibrate every hour if you want.

I've had it for well over a year now and it's working just fine. Seems to keep time reasonably well. The features are reasonably easy to access in the dark, if you hold down the light button.

It's a little thicker than an average watch, but not by much. It's not the most beautiful watch out there - it's a basic black plastic and rubber watch - but it looks fine and suitable for professional wear.
