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 GMT automatic movement trusted for stable performance and practical dual-time functionality. It suits travel watches, business use, and everyday wear.
First, the built-in GMT hand allows clear tracking of a second time zone. The red arrow hand points to a 24-hour scale on the bezel or chapter ring. As a result, users can read two time zones at a glance.
In addition, the movement features 24 jewels. These reduce friction and improve long-term durability. It runs at 21,600 vibrations per hour (3 Hz), delivering a smooth and consistent sweep.
Moreover, the NH34 offers a power reserve of approximately 41 hours. Therefore, the watch continues running even after a full day off the wrist. Hacking seconds and manual winding also allow precise time setting. At the same time, the bidirectional automatic winding system improves efficiency. Normal wrist movement can quickly generate sufficient power.
The movement measures only 5.32mm in height. Because of this, it fits a wide range of case designs. It is also easy to service, which makes it ideal for mid-range GMT watch projects.
Through an exhibition case back, the rotor and internal structure remain visible. This adds mechanical appeal and enhances perceived value.
Every unit goes through our standard quality checks: accuracy testing, power reserve verification, and water-resistance simulation — ensuring consistent performance across orders.
