Time to give your watch the ultimate upgrade? Say hello to the Original NH35A Automatic Mechanical Movement — the modder’s favorite, trusted by collectors and watchmakers worldwide. With 24 jewels, a sleek black datewheel with crisp white text, and bulletproof reliability, this is the go-to movement for those who take horology seriously.


🕰️ Why the NH35A Reigns Supreme:

Genuine Japanese Engineering

Straight from TMI (a division of Seiko), this is the authentic NH35A, not a clone or knockoff. It’s built to last, finely tuned, and loved for its balance of durability, accuracy, and affordability.

Smooth Automatic Movement

This self-winding mechanical marvel keeps ticking with the motion of your wrist — no batteries, no fuss. Or wind it manually via the crown for old-school satisfaction.

24 Jewel Perfection

With 24 embedded jewels, friction is minimized, and wear and tear are drastically reduced. Translation: longer life, smoother operation, and higher accuracy.

Black Datewheel + White Text

A sleek, stealthy aesthetic that enhances legibility and adds a custom modding flair. Whether you're building your dream diver or revamping a classic, this detail sets it apart.

Easy to Swap & Upgrade

Compatible with a wide variety of watch cases, the NH35A is the perfect replacement or mod mechanism for Seiko mods, custom builds, or revitalizing old timepieces.
