Questions, Answered

Everything worth knowing before you build.

NH34 vs NH35 vs NH36 vs NH38 vs NH70 — what is the actual difference?

They are the same movement — only the complication differs. Every one: 24 jewels, −20 to +40 sec/day, 21,600 vph, 41h power reserve, casing Ø29.36mm with the spacer.

| Movement | Shows |
|---|---|
| **NH34** | Date + GMT |
| **NH35** | Date |
| **NH36** | Day date |
| **NH38** | Open Heart |
| **NH70/71/72** | Skeleton |

All of them hack (the seconds hand stops while you set). On the NH38 and the NH70 family the crown has one click and it sets the time, so a no-date dial belongs on an NH38 — there is no empty date position to pull past.

Only the height differs: 7.59mm installed, 7.99mm for the NH34. That extra 0.4mm of hand stack is why a GMT needs a case built for it. Otherwise the family is interchangeable — you are choosing a dial and a crown behaviour, not a different-sized engine.

I plan on buying the NH38 movement from you. Do I still need to purchase this spacer or is that included?

Hi Jesse,

Thanks for expressing interest in our mod parts!

You won’t need to purchase the dial holding spacer separately with your NH38 order. The DHS is only needed if your original one is damaged or has been modified beyond standard use.

Hope this clears things up! Let me know if you have any other questions.

Best regards,
Adriel
