Product Overview

Description

This Seiko Nautilus Open Heart combines a 40 mm stainless-steel case with a mechanical open-heart dial and an orange leather strap.

The dial opening lets part of the movement remain visible, adding depth and character to the overall design.

The bright strap colour gives the otherwise classic steel profile a more expressive, contemporary finish.

Movement

Seiko NH35 Automatic

Automatic mechanical movement powered by wrist motion for a traditional self-winding experience.
