Technical Aspects
The Seiko NH36 is a popular automatic watch movement known for its reliability and affordability. It’s a workhorse movement found in many watches, both entry-level and higher-end. Understanding its technical aspects can help you appreciate its design and performance.
Mechanism and Workings
The NH36 is a self-winding mechanical movement, meaning it uses the movement of your wrist to wind the mainspring. The movement consists of several key components:
- Mainspring: Stores the energy that powers the watch.
- Rotor: A weighted component that rotates with the movement of your wrist, winding the mainspring.
- Gear train: A series of gears that transmit power from the mainspring to the hands.
- Escapement: A mechanism that releases energy from the mainspring in controlled bursts, allowing the watch to tick.
- Balance wheel: A weighted wheel that oscillates at a specific frequency, regulating the watch’s timekeeping.
- Hairspring: A delicate spring that controls the balance wheel’s oscillation.
When you wear the watch, the rotor spins, winding the mainspring. As the mainspring unwinds, it releases energy through the gear train, driving the hands. The escapement regulates the release of energy, ensuring smooth and consistent timekeeping. The balance wheel and hairspring control the frequency of oscillation, determining the watch’s accuracy.
Power Reserve and Accuracy
The NH36 typically has a power reserve of around 41 hours. This means that once fully wound, the watch will run for approximately 41 hours without any additional winding. However, the actual power reserve can vary slightly depending on the watch’s design and usage.
The accuracy of the NH36 movement is generally within -20 to +40 seconds per day. This means that the watch can gain or lose up to 40 seconds per day. While this may seem like a lot, it’s considered acceptable for a mechanical watch. Factors like temperature, magnetic fields, and shock can all affect the watch’s accuracy.
Comparison with Other Movements
The NH36 is often compared to other popular automatic movements like the ETA 2824-2 and the Miyota 8215. Here’s a comparison of some key features:
| Feature | NH36 | ETA 2824-2 | Miyota 8215 |
|---|---|---|---|
| Price | Lower | Higher | Lower |
| Accuracy | -20 to +40 seconds per day | -10 to +20 seconds per day | -20 to +40 seconds per day |
| Power Reserve | 41 hours | 38 hours | 42 hours |
| Availability | Widely available | Widely available | Widely available |
The NH36 is generally considered a good value for its price, offering decent accuracy and features. However, the ETA 2824-2 is known for its higher accuracy and smoother operation, but it comes at a higher price. The Miyota 8215 is a more affordable alternative, offering similar features to the NH36.
Maintenance and Repair
The NH36 is a relatively robust movement that requires minimal maintenance. However, like any mechanical watch, it’s important to have it serviced regularly.
A general rule of thumb is to service your watch every 3-5 years, depending on usage.
During a service, a watchmaker will clean, lubricate, and adjust the movement, ensuring optimal performance. If the watch is damaged or malfunctioning, it may require repair. Common repairs include replacing worn parts, fixing broken gears, or adjusting the timing.
