Discover the Enhanced Modifled Seiko NH35 Movement

Modified Seiko NH35 Automatic Movement – Refined Small Seconds Precision

We modify the proven Seiko NH35 automatic movement in our factory to deliver reliable performance with a clean, elegant small seconds sub-dial at 6 o’clock. This position creates natural balance on the dial and keeps the layout simple and easy to read.

The movement uses 28 precision-set jewels to reduce friction and wear. This design choice improves smoothness, enhances accuracy, and extends service life — key benefits for watches that see daily use.

The NH35 maintains its slim profile (5.32mm height), 21,600 vph beat rate, 41-hour power reserve, hacking seconds, and bidirectional automatic winding. It winds efficiently through normal wear and keeps consistent time (±15 to ±25 seconds/day) without fuss.

The clean, minimalist architecture suits both classic dress watches and modern tool designs. Brands and makers choose this movement because it combines dependable Japanese engineering with straightforward servicing.

As a professional watch manufacturing factory, we handle customization directly:

• Add brand logo engraving on the rotor or bridges
• Adjust finishing (perlage, Côtes de Genève, or color accents)
• Include small functional upgrades or layout tweaks
• All with strict quality checks and scalable production

This modified NH35 offers exceptional value: solid reliability, refined small seconds aesthetics, and easy customization — ideal for mid-range mechanical watches that need to perform long-term.
