Published in Watch Movement Reliability 3 mins read

Yes, the Seiko NH35 movement is widely considered highly reliable and has earned a strong reputation for dependability within the watchmaking industry.

Why is the Seiko NH35 Considered Reliable?

The NH35 has cemented its position as a trusted and go-to movement for many watchmakers globally, extending its presence far beyond Seiko's own brands. Its robust construction and consistent performance are key factors contributing to its reliability.

Widespread Trust and Adoption

The NH35 movement has gained the trust of watchmakers around the globe due to its established reputation for accuracy and dependability. Its integration into a vast array of watches, particularly by independent and microbrand watchmakers, signifies a community-wide endorsement of its excellence. This widespread adoption is a testament to its consistent performance and ease of use.

Robust and Dependable Design

Designed for durability, the NH35 is an automatic mechanical movement known for its straightforward yet effective engineering. It is built to withstand daily wear and tear, offering consistent timekeeping with minimal fuss. While its accuracy might not rival that of a certified chronometer, it typically performs well within acceptable industry standards for an affordable automatic movement.

Accessibility and Serviceability

One of the factors contributing to the NH35's long-term reliability is its accessibility for service and repair. Its commonality means that parts are readily available, and many watch technicians are familiar with its architecture, making maintenance straightforward and cost-effective. This ease of service helps ensure a long operational lifespan.

Key Characteristics of the NH35 Movement

The features of the Seiko NH35 contribute significantly to its user-friendliness and overall reliability:

Feature Description Benefit for Reliability
Automatic Winding Winds the mainspring using the motion of the wearer's wrist, eliminating the need for batteries. Consistent power supply with regular wear, reducing manual interaction.
Hand-Winding Allows the watch to be manually wound via the crown, useful for starting a stopped watch or topping up power. Ensures the watch can always be powered up, even if not worn.
Hacking (Stop Seconds) The second hand stops when the crown is pulled out, allowing for precise time setting. Enables accurate synchronization, a hallmark of dependable timekeeping.
24 Jewels Contains 24 synthetic ruby jewels that reduce friction on moving parts. Minimizes wear and tear, enhancing the longevity and smooth operation of the movement.
Date Complication Displays the current date, a practical feature for daily use. Adds functionality without compromising core reliability.

Maintaining NH35 Reliability

While inherently reliable, proper care can extend the lifespan and maintain the accuracy of your NH35-powered watch:

  • Regular Wear or Winding: To keep the movement lubricated and active, wear your watch regularly or hand-wind it every few days if it's part of a rotation.
  • Avoid Extreme Shocks: While durable, like any mechanical movement, severe impacts can affect its internal components.
  • Keep it Clean: Avoid prolonged exposure to dust or extreme temperatures.
  • Periodic Servicing: Although robust, a mechanical watch benefits from professional servicing every 5-7 years to clean, lubricate, and adjust the movement, ensuring optimal performance for decades. For more information on watch care, consult reputable watch enthusiast resources.

The Seiko NH35 movement is a dependable workhorse, prized for its consistent performance, ease of use, and robust nature, making it a favorite among watchmakers and enthusiasts alike.
