Heart of the ocean

Our quartz watch batteries last on average 2 years until a battery replacement is necessary.

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. 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 Seiko mechanical movements. 

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