Its stopwatch function provides 1/100th-second accuracy, captures split times, and 1st/2nd place times while its multi-alarm function flashes with a buzzer that sounds for alarms. With automatic calendar function. Precise quartz movement provides reliable accuracy within 15 seconds each month. The 3/4"-wide resin band fits wrists 5"-8 1/2" in circumference and is attached to the case with steel lug screws. Case: 2 1/4" H x 1 3/4" W x 1/2” D. (4 3/4 oz.)
