Aquazure movement
Quartz
Quartz watches are battery powered. We use Quartz Swiss Ronda 515. The seconds hand of a quartz watch "ticks". Essentially every one second equals one "tick."
Automatic
In contrast to quartz watches, an automatic watch converts your everyday motion into energy — no battery necessary. The seconds hand of an automatic watch "glides", in contrast to the "ticking" movement of a quartz watch. We use Automatic Japan SEIKO NH35A. The hand moves more frequently than only once per second.

Finally, our automatic watches also feature a date window, while the quartz versions do not.
