Built-in GMT hand for second time zone tracking — the classic red arrow hand points to the 24-hour scale on the bezel or chapter ring
The Seiko NH34 is a proven, factory-modified GMT automatic movement that’s widely trusted for its solid performance and practical dual-time functionality — perfect for travelers, professionals, or anyone who needs to track two time zones at once.
Key features include:
Built-in GMT hand for second time zone tracking — the classic red arrow hand points to the 24-hour scale on the bezel or chapter ring
24 jewels for smooth, low-friction operation and long-term durability
21,600 vph (3 Hz) for a steady, accurate sweep
41-hour power reserve — enough to keep running over a weekend off the wrist
Hacking seconds and manual winding for easy, precise setting
Bidirectional automatic winding — efficient power generation from normal wrist movement
The movement is robust, slim (5.32mm height), and easy to service — making it a favorite base for mid-range mechanical watches with GMT capability. The rotor is visible through an exhibition caseback, showing the clean finishing and reliable mechanics in action.
As a professional watch manufacturing factory, we offer full OEM customization on the NH34:
Brand logo engraving on the rotor or bridges
Custom GMT bezel inserts or chapter ring markings
Alternative finishing (perlage, Côtes de Genève, or color accents)
Small functional tweaks or strap/bracelet matching
Every unit goes through our standard quality checks: accuracy testing, power reserve verification, and water-resistance simulation — ensuring consistent performance across orders.
The NH34 GMT is a practical, cost-effective GMT automatic movement — ideal for building reliable dual-time watches without high-end pricing.
