Collezione: Seiko Movements

NH Series Movements

The architectural foundation of professional watchmaking. Our curated selection of genuine NH-series calibers represents the pinnacle of mechanical versatility and industry-leading reliability. Each movement is engineered for high-torque performance, featuring a 21,600 bph vibration frequency, Diashock impact resistance, and bi-directional winding efficiency.

Whether you are building a specialized GMT, a classic diver, or a technical skeletonized masterpiece, these workhorse calibers provide the mechanical precision required for high-end horological engineering.

Technical Breakdown by Caliber

• NH34 (GMT): The definitive dual-time caliber, featuring an independent GMT hand and increased hand-stack height for multi-layered dial configurations.

• NH35 (Date): The global standard for reliability; a robust automatic movement with a quick-set date complication and hacking/hand-winding capabilities.

• NH36 (Day-Date): Engineered for maximum utility, providing a stable platform for timepieces requiring both day and date complications.

• NH38 (Open-Heart): A technical variant designed without a date complication to allow for unobstructed views of the balance wheel through "open-heart" dial apertures.

• NH70 / NH71 (Skeleton): The apex of aesthetic engineering. These calibers feature a factory-skeletonized bridge structure (Grey or Gilded finishes) for high-concept builds that demand full mechanical transparency.
