Seiko Movement

Power your build or complete a restoration with our Seiko Movement, a reliable and widely used automatic, mechanical, or quartz movement platform engineered for durability, accuracy, and ease of servicing. These movements—such as the popular NH35, NH36, NH37, NH38, NH39, NH70, 7S26, 4R36, and other Seiko-based calibres—are ideal for watchmakers, modders, and hobbyists working on custom builds or replacing worn internal components.

Each Seiko-compatible movement features smooth winding, stable timekeeping, and dependable construction. Automatic variants include hacking seconds, hand-winding capability, and strong power reserves, while mechanical and quartz models offer clean installation for a wide range of watch projects.

Perfect for SKX-style builds, 5KX conversions, Turtle, Samurai, Monster, and other Seiko mod platforms (fitment varies by case), the Seiko Movement provides excellent reliability and universal compatibility for professional-level watchmaking and modding.
