Seiko NH35: A Reliable Workhorse Movement for Watch Enthusiasts
Share
What is the Seiko NH35?
The NH35 is an automatic movement developed by Seiko, a brand renowned for its long-standing tradition of innovation and craftsmanship. Part of Seiko’s NH series, this movement is based on Seiko’s own in-house 4R35 caliber, which is commonly found in many of Seiko’s own watches. The NH35 is specifically designed for third-party brands and modders, making it widely available and incredibly popular among those looking to create or modify watches.
Key Specifications
Before we get into why the NH35 is so highly regarded, let’s take a look at its core specifications:
• Type: Automatic (self-winding) with manual winding capability
• Jewels: 24 jewels
• Power Reserve: Approximately 41 hours
• Frequency: 21,600 beats per hour (6 beats per second)
• Accuracy: -20 to +40 seconds per day
• Hacking: Yes (the second hand stops when the crown is pulled out to set the time)
• Shock Resistance: Diashock system
Why the NH35 is Popular
1. Dependability
One of the primary reasons the NH35 has earned its reputation is its dependability. Built with Seiko’s high standards, this movement can withstand daily wear and tear with ease. The movement is also incredibly easy to maintain, which is a key factor in its popularity among both professional watchmakers and DIY modders.
2. Affordability
While Seiko’s higher-end movements like the 6R series or the Grand Seiko calibers offer more refined finishes and complications, the NH35 provides excellent performance at a fraction of the price. Its affordability makes it accessible to a wider audience, from microbrands to independent modders. Despite its low cost, the NH35 doesn’t compromise on quality, making it an excellent value proposition.
3. Modding and Versatility
The NH35’s popularity in the modding community is no accident. Its robust design, along with its relatively easy installation process, makes it a versatile movement that can be used in a wide range of watch designs. Many third-party watch brands opt for the NH35 because it strikes a balance between reliability and cost-effectiveness. Moreover, because it’s based on Seiko’s in-house technology, it’s easy to source replacement parts and components if needed.
4. Accuracy and Hacking Feature
Though the NH35 may not be as precise as some Swiss movements, its accuracy falls within an acceptable range for most everyday users. Additionally, the inclusion of a hacking feature—where the second hand stops when you adjust the time—adds an extra layer of precision when setting the time. For many, this is a significant feature that enhances the overall user experience.
5. Power Reserve
With a power reserve of approximately 41 hours, the NH35 can last nearly two full days without being worn or wound. This is more than sufficient for the average wearer and aligns with other movements in the same category.
Who Should Consider the NH35?
The NH35 is an excellent choice for those who are either new to the world of mechanical watches or those looking for a reliable movement to power their custom watch projects. Its combination of reliability, ease of use, and affordability make it a perfect fit for:
• Watch Modders: If you’re into customizing watches, the NH35 is a great starting point.
• Microbrand Watchmakers: Many independent brands use the NH35 in their watches, and for good reason—it’s cost-effective and trustworthy.
• Everyday Watch Wearers: If you’re looking for a dependable automatic movement without breaking the bank, watches powered by the NH35 offer fantastic value for money.

Its durability, affordability, and versatility make it an appealing option for both professionals and hobbyists. Whether you’re designing your own watch or simply looking for a reliable automatic timepiece, the NH35 movement won’t disappoint.
