Model Timer-stopwatch For 20 Min

Animatiebeschrijving:

This is a mechanical timepiece which can be set to the desired time of 1 to 20 minutes. The timer has a unique roller pendulum and amplitude adjustment system on the back wall.
Our timer works from the usual clerical gum. When you move the arrow and lower the handle the countdown starts. Both minutes and seconds arrows operate.
