Quartz

A quartz movement in a watch is a type of electronic movement that uses a small piece of quartz crystal to keep time. When an electrical current passes through the crystal, it vibrates at a consistent frequency, which regulates the timekeeping mechanism in the watch. This makes the seconds hand tick once per second in a smooth and continuous motion.

Automatic

An automatic movement, on the other hand, is a mechanical movement that is powered by the movement of the wearer's wrist. As the wrist moves, a rotor inside the watch spins and winds the mainspring of the watch, which powers the timekeeping mechanism. The seconds hand on an automatic watch moves in a sweeping motion, making multiple small ticks per second, rather than once per second like a quartz watch.

In addition, our automatic watches feature an open case back showing the intricacies of our mechanical movements. (edited)
