I use a watch with an hourly chime. Casio has quite a few good sturdy workhourse watches with this feature. Timex has them too, but they switched to plastic watchfaces and now they scratch easily. My watch also has a built in timer. I press the timer button to get a get a 1, 3, 5, 10, 15, 20, or 30 minute timer. Use it for my tea at least twice a day! And it is good if you are into Pomodoro method type techniques for time management and to time rest periods between weightlifting sets.

Mine is a Casio 3225 W-214 HC. The plastic watchband is garbage, but was easy to just swap out with a nice black metal flat link one and you'd never know it wasn't stock. There are several variations.
