From the iconic nautilus and Japanese Seiko comes the hybrid, Seikonaut.

Our own reinterpretation, every part, notches and crevices was redesigned from scratch. Creating a whole new allure and a refinement of the iconic design.

Only 10 pieces were made with these luxurious and genuine Top Grain Crocodile Leather Strap. This bespoke leather strap itself cost much more than the case itself.

This Seikonaut case comes complete with clear AR sapphire, sapphire caseback, screw down crown and crocodile leather strap.

Designed to fit all of our dials (28.5mm) and original NH movements (grey dial holding spacer).

**Please note that assemble watch option will assemble the entire timepiece ready for use and requires 2-5 business days prior to shipping.

Using this mod part for: Seiko Samurai
Great Quality!

The quality and finishing of the case is perfect with great attention to detail such as the polished chamfer on the lugs and bezel. The crocodile leather is soft and flexible while perfectly following the contours of the case. I Shall be pairing it with the birch dial and black nautilus hands.
