This analog chess timer is the perfect addition to any tournament play or classroom match. It features the Royal Chess emblem for a more official appearance. If you are looking to make your matches more competitive, this clock is a great way to level up, or get your games moving along faster. The chess timer is lightweight, portable and so simple to operate. All it takes is the click of a button! The unit starts and stops by pushing the button on top but both clocks can be frozen by keeping the buttons at an even level. Both clocks are easy to reset on the back and have a locking clip for each top button. This game timer features a Quartz clock, which uses an electronic oscillator that is regulated by a quartz crystal to keep time.
