Quartz watches are battery powered. We use Swiss-made Ronda 515 Quartz. The seconds hand of a quartz watch "ticks". Essentially every one second equals one "tick."
Our quartz watch batteries last on average 2 years until a battery replacement is necessary. The case back features a custom design inspired by the cosmos.
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 Swiss Automatic Sellita SW200-1. The hand moves more frequently than only once per second.
In addition, our automatic watches feature an open case back showing the intricacies of our Swiss mechanical movements.
Finally, our automatic watches also feature a date window, while the quartz versions do not.
