TIMER (20 minutes)
One of the most beautiful UGEARS models, the Timer is an exquisite mechanical device, which can be set for any time ranging from 1 to 20 minutes. Wind up the alarm mechanism, and the alarm will go off when time runs out. The Timer has a unique roller pendulum and an amplitude adjustment system on the back wall. Just like other UGEARS models, the Timer is powered by plain office rubber bands. We have improved this model several times to achieve perfect results. Now everyone can build this amazing clockwork mechanism, equally fit for both work desks and living rooms.
