The Quartz Cuckoo Clock offers the same classic stying as their mechanical counterparts, but incorporate modern technology. Quartz clocks are battery-operated relying on quartz timepieces to keep the time. While quartz cuckoo clocks may feature the traditional weights found on the mechanical clocks, these weights are purely for design. The only real difference between mechanical and quartz cuckoo clocks is the power source. Both feature the classic movements on the hour, cuckoo sounds, and of course, craftsmanship. Quartz cuckoo clocks may also feature a light sensor or setting that prevents the clock from making noise after dark.
