Unique timer is easy to use. Counts down, alarms, and functions as a stopwatch. One of the handiest timers ever designed- holds your keys or hooks onto your lab coat buttonhole. Four-digit LCD display always shows time remaining in hours and minutes. Program it in the countdown mode in minute increments from 20 hours to 1 minute.
