4 rules to select the right watch size.

Case diameter

1. Our watches are generally large, even 42MM. However, due to the style of the watch you might consider a larger size than you usually wear.

Wrist size

Case thickness

2. The 45MM case watches are 12MM thic whereas 42MM case watches are 11MM thick.

Band width

3. The 45MM case watches have 20MM wide watch bands whereas 42MM case watches have 18MM wide watch bands.

Band type

4. Watches with a steel bracelet are heavier than with a leather watch band by 90 gram.

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.
