The Perfect Digital Watch with all the Bells & Whistles!
Color: Black/Gray
I always buy this kind of watch, and so does my adult daughter. It has a timer, 3 alarm settings, push button light, easy to set, and other features that I don't use, like, track timers, Occasion settings, Beeps & Chimes, On or Off. I use it for timing my Laundry, taking pills, timing things in the kitchen. I just can't live without it! My daughter used it for timing on her Breast Feeding Schedule, so no matter what room she was in, or what she was doing, she would always hear that alarm!
