Premium Custom Skeletonized Rotor - NH / 4R Family

Premium Rotor Upgrade for NH and Seiko 4R Series Movements – A Simple Way to Enhance Your Watch

Upgrade your NH35, NH36, NH38, NH39, NH70, NH71, or Seiko 4R series movement with a custom half-skeletonized rotor designed to improve both aesthetics and performance. Whether you are a watch enthusiast looking to personalize your Seiko timepiece or a builder assembling custom watches, this rotor is a direct replacement for the stock NH and 4R rotors, offering a luxury finish with enhanced weight distribution for smoother winding.

Why Upgrade Your NH or 4R Movement Rotor?

Seiko and NH-based movements are known for their reliability, but their stock rotors are often plain and unremarkable. If your watch has an exhibition caseback, the movement is always visible—and a standard plain & boring rotor does not do justice to its mechanical beauty. This custom skeletonized rotor adds a high-end, premium look while ensuring efficient automatic winding thanks to its tungsten-weighted outer edge.

Who Is This For?

• Seiko Owners – Upgrade the rotor on your 4R-powered Seiko for a more refined and stylish movement finish.
• Watch Enthusiasts – Personalize your NH-powered watch with an elegant, skeletonized rotor.
• Watch Modders & Builders – Enhance your custom builds or homage watches with a rotor that matches the case design.
