Unlocking the Secrets of NH35 and NH36 Movements for Watch Collectors

When it comes to watch collecting, enthusiasts often find themselves diving deep into the world of horology to understand the inner workings of their timepieces. Two movements that have gained popularity among watch aficionados are the NH35 and NH36 movements. These movements, produced by Japanese manufacturer TMI (Time Module Inc.), offer an intriguing blend of reliability and affordability. In this article, we’ll unlock the secrets of NH35 and NH36 movements to provide valuable insights for watch collectors.

The Basics of NH35 and NH36 Movements

The NH35 and NH36 movements are automatic movements, also known as self-winding movements. This means they are powered by the kinetic energy generated through the wearer’s wrist movements. These movements belong to a family known as the Seiko Instruments Inc. (SII) Caliber NH, and they are frequently used in both budget-friendly and mid-range watches.

One of the key differences between the NH35 and NH36 movements lies in their date complication. The NH36 features a nh35 vs nh36  window, whereas the NH35 does not. This added feature can be quite handy for those who prefer having the date displayed on their watch.

Reliability and Durability

One of the reasons these movements have gained popularity among watch collectors is their reliability and durability. The NH35 and NH36 movements are known for their robust construction and resistance to wear and tear. They feature 24 jewels, which reduce friction within the movement, leading to smoother operation and increased longevity.

Moreover, the NH35 and NH36 movements are often compared to the renowned Swiss ETA 2824-2 movement in terms of reliability. While they may not have the same prestige as their Swiss counterpart, they offer comparable performance at a significantly lower cost, making them an attractive option for watchmakers and collectors alike.

Customization and Modding Potential

Watch collectors and enthusiasts often enjoy the opportunity to customize or modify their timepieces. One of the secrets of the NH35 and NH36 movements is their modding potential. These movements have standardized dimensions and are widely available, making it relatively easy to find replacement parts or upgrade components.

Many watch modders appreciate the NH35 and NH36 movements for their versatility. You can swap out components like hands, dials, and even the movement itself to create a unique and personalized watch. This modding potential has spawned a thriving community of watch enthusiasts who enjoy tinkering with their timepieces to create one-of-a-kind watches.


Another secret that makes the NH35 and NH36 movements attractive to watch collectors is their affordability. These movements provide a cost-effective alternative to pricier Swiss movements while maintaining a high level of reliability. This affordability allows watchmakers to offer timepieces with NH35 or NH36 movements at a reasonable price point, making them accessible to a wider audience of collectors.


For watch collectors, understanding the inner workings of their timepieces is part of the fascination with horology. The NH35 and NH36 movements offer a blend of reliability, durability, and affordability that has endeared them to collectors and watchmakers alike. Their versatility for customization and modding only adds to their appeal. So, whether you’re a seasoned collector or just starting your journey into the world of watches, unlocking the secrets of NH35 and NH36 movements can open up a world of possibilities for your collection.
