​The NH35A is widely recognised as one of the most dependable automatic watch movements on the market. Celebrated for its durability, accuracy, and ease of maintenance, this versatile calibre has become a go-to choice for both watchmakers and enthusiasts around the world.

​

Key Features:

• Automatic Self-Winding: Powered by the wearer’s motion, the NH35A eliminates the need for batteries or frequent manual winding.

• Hacking and Hand-Winding Capabilities: Offers a hacking function—stopping the second hand during time setting—for precise adjustments, along with manual winding to top off the power reserve as needed.

• Date Function: A clearly legible date window is positioned at 3 o’clock, adding practical functionality.

• Accuracy: Delivers a standard daily deviation of approximately -20 to +40 seconds, making it reliable for everyday wear.

• Power Reserve: Boasts over 41 hours of power reserve, allowing the watch to keep time even after a day or two off the wrist.

• 24 Jewels: Jewel bearings reduce internal friction, promoting smooth operation and long-term performance.

• Diashock Protection: Seiko’s proprietary anti-shock system helps protect the movement from impact, increasing its resilience to knocks and drops.

History and Manufacturer of the NH35A Movement

The NH35A is produced by SII and TMI (Seiko Instruments Inc.), subsidiaries of the Seiko Group, based in Japan. Originally developed as part of the Seiko 7S family of movements, the NH35A is essentially a commercial or OEM (Original Equipment Manufacturer) version of the Seiko Calibre 4R35.

While the 4R35 is typically reserved for Seiko-branded watches, the NH35A is sold to third-party brands around the world.

​

Key points in its development history:

• Based on 7S26 Movement: The NH35A evolved from the legendary Seiko 7S26, which was known for its reliability but lacked hacking and manual winding.

• Improved Features: Introduced with upgrades like hacking and hand-winding, the NH35A brought more functionality to the same bulletproof architecture.​​​​​​​​​​​​​​​​

• Today, the NH35A stands as a symbol of affordable and reliable mechanical precision, backed by Seiko’s decades of innovation and reputation in horology.
