Choosing the right movement is one of the most important decisions when selecting or building a watch.
The NH35, NH34, and NH70 series are all produced by TMI (Time Module Inc.) and are widely used across modern automatic watches. While they share a similar foundation, each one offers a different experience depending on how you plan to wear your watch.
If you’re deciding between them, this guide breaks it down clearly.
What These Movements Have in Common
All three movements are:
- Automatic (self-winding)
- Hand-windable
- Equipped with hacking seconds
- Known for durability and reliability
They’re built to be worn daily and serviced easily, which is why they’re commonly used in custom watches.
