This powerful Punching Watch can be used for personal reminders (medication or medical conditions, time management, self regulation, appointments, cooking, parking, etc.). Alarm will vibrate the time set twice a day; once for AM and once for PM. Simple multi-function two-button operation makes setting this watch a breeze. Pull the stem head out to the first position and set the time, then gently pull it a bit further to the second position to set the alarm. To turn the alarm function on and off, pull the alarm stem slightly for on and then push it back in to shut it off. Watch has a black plastic casing with a golden face, hour, minute, second hands and a red-tipped alarm hand. A black rubberized band with ventilation holes completes this great watch. Uses one SR-626 battery for the clock and a CR-2032 for the vibration motor; installed. 1-year warranty.
