The Seiko NH36 movement is a popular choice among watch enthusiasts and DIY watchmakers for its durability, reliability, and affordability. As part of the Seiko family, it carries a legacy of precision and craftsmanship. Whether you are looking to build a custom watch or upgrade your current timepiece, understanding the Seiko NH36 movement is essential.
This guide will explore everything you need to know about the Seiko NH36, from its technical specifications to its benefits and common applications.
What is the Seiko NH36 Movement?
The Seiko NH36 movement is an automatic movement designed and manufactured by Seiko Instruments. It is part of the Seiko 4R family and is commonly used in mid-range watches. Known for its robustness and precision, the NH36 movement has become a staple in the watch industry, especially for affordable mechanical watches.
The NH36 is essentially an updated version of the earlier Seiko 7S36 movement, offering additional features, including a day-date complication and hacking seconds. This means the second hand can be stopped when setting the time, allowing for more precise synchronization with a reference time.
Key Features of the Seiko NH36 Movement
-
Day-Date Complication: The Seiko NH36 movement includes both a day and date display, making it a convenient choice for those who want a quick reference to the date and day of the week.
-
Hacking Seconds: The ability to stop the second hand while setting the time ensures that you can synchronize your watch accurately with another timepiece.
-
Automatic Winding: The NH36 is powered by the movement of the wearer's wrist. When the watch is worn regularly, the rotor winds the mainspring, eliminating the need for batteries.
-
Manual Winding Option: In addition to automatic winding, the NH36 can be manually wound, which comes in handy if the watch has not been worn for a while.
-
Durability: As a product from Seiko, the NH36 is known for its high level of reliability and long-lasting performance, making it a great choice for watch enthusiasts who enjoy building and customizing their own timepieces.
How the Seiko NH36 Movement Works
The Seiko NH36 movement works by harnessing the natural motion of the wearer's wrist. When the rotor inside the movement is turned by movement, it winds the mainspring, which provides the energy needed to power the watch. This energy is released gradually, moving the hands and powering the watch's functions.
The day and date complications are updated automatically once every 24 hours, and the watch maintains precise timekeeping as long as it is kept moving. If the watch remains unworn for a period of time, it can be wound manually by turning the crown.
Advantages of the Seiko NH36 Movement
-
Affordability: Compared to other automatic movements, the Seiko NH36 offers excellent value for money, making it accessible to a wide range of customers.
-
Reliability: Seiko is renowned for its reliability, and the NH36 is no exception. It is a time-tested movement that can withstand daily wear and continue to perform well over the long term.
-
Versatility: The NH36 is versatile enough to be used in a wide variety of watches, from entry-level to mid-range models, and even in custom-built projects.
-
Ease of Repair: Because it is widely used in the watchmaking community, spare parts for the NH36 are easily accessible, and the movement is relatively easy to repair or service.
-
Precision: The Seiko NH36 offers excellent timekeeping accuracy, with a typical deviation of -20 to +40 seconds per day. This is more than acceptable for most everyday watch enthusiasts.
