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.

Customers praised this precision-made stem for NH movements as "OEM quality" with perfect fitment.

My Tiffany Seikonaut 36mm

I ordered the stem with the Seikonaut 36mm case, it is a perfect fit. Lucius offers fast shipping and the delivery is outstanding. It looks so classy. Stem to case fitment is excellent. I cannot thank Lucius enough for precutting the stem to fit my Seiko NH35A movement. Less hassle. Perfect case size, the 36mm wears like a 40mm. Thank you. Jorge

Good selection, good prices

I just needed a stem for the NH36 and Lucius had them at a very good price. Shipping for only one inexpensive item was very reasonable and it arrived several weeks later (customs, etc). I'll be shopping on the site soon for a case as I plan to be designing my own watches

I have selected your Seiko NH Automatic movement stem / Part code 03512000 - Will this fit my Seiko NE15C movement which is the same as the 6r15 movement - thanks Andrew...

Hello Andrew!

Thank you for expressing interest in our mod parts!

Unfortunately, I have never worked with NE15 movement so I cannot advise on it compatibility. I highly recommend you contact Seiko Service Centre to advise on the parts compatibility.

Hope this helps. Let me know if you have any more questions.

Cheers,
Adriel
