About this product Timer, clock, and alarm clock in one: As a regular clock, it offers a switchable 12/24-hour display mode. As a timer, it features both countdown and count-up timers, with an orange circle countdown function for excellent visual appeal. Its desktop design allows the timer to be placed on a tabletop and viewed from a non-flat angle for optimal viewing. A must-have timer for classrooms, available in white and pink, measures 3.15 by 3.15 inches. Visual digital timer with LCD screen – Highly readable and simple to operate, rotating the knob increases or decreases time in 1-minute increments, up to 60 minutes.
