Designed for those who appreciate the convenience of an automatic movement without the need for batteries, this 39mm model offers a versatile look suitable for office wear and weekend outings, though its 30m water resistance means it is better suited for light splashes rather than professional diving or heavy swimming.

FAQs

Does this watch require batteries?

Can I wear this watch while swimming?

What is Hardlex crystal?

Hardlex is Seiko's proprietary mineral glass that is hardened to provide greater scratch and impact resistance than standard glass.

How long does the power reserve last?

Is the watch band adjustable?
