W-738H-1AJF
This midsize square digital watch features vibration alerts for everyday, sports and work use. Closely spaced band holes allow finer adjustment so vibrations can be felt comfortably at the wrist. Large LCD digits improve readability, while the start/vibration-setting button and central light button are designed for easy operation. A vibration alarm, 10-bar water resistance, approximately ten-year battery life and LED backlight provide a practical function set.
