NH35 vs NH36 vs NH34: Which Movement for Your Build
One Family, Three Personalities
Most mods run on the NH family, and beginners ask the same question: which one do I actually need? The good news is the NH35, NH36 and NH34 share the same case footprint, so a case built for one usually takes all three. The differences are complications, clearance and price. Here is the honest comparison.
Side-by-Side Comparison
| Feature | NH35 | NH36 | NH34 |
|---|---|---|---|
| Date | Yes | Yes | Yes |
| Day (weekday) | No | Yes | No |
| GMT hand | No | No | Yes (fourth hand) |
| Dial diameter | 28.5mm | 28.5mm | 28.5mm |
| Hand stack height | Standard | Standard | Taller (GMT) |
| Beat rate | 21,600 vph | 21,600 vph | 21,600 vph |
| Power reserve | ~41h | ~41h | ~41h |
| Typical price | Lowest | Mid | Highest |
Accuracy behavior is similar across the family — expect typical daily rates around ±20 seconds until regulated. Our NH35 vs 4R35 article covers the factory alternative.
Which One Should You Build With?
- First build, date only: NH35. Cheapest, most compatible, endless dial choice
- Day-date look (classic SKX/Seiko 5): NH36. The day wheel is the only real difference — and it is worth it if you want that classic layout
- GMT build (Pepsi/Batman style): NH34. Requires a GMT case with clearance for the taller hand stack — not every case accepts it
- No date at all (sterile/minimal): NH38 — date-less dials look cleaner
The NH34 Gotcha
The GMT hand stack sits higher, so an NH34 needs a case with enough internal clearance and a dial with a GMT hand hole. Ordering an NH34 into a case that was never designed for GMT is a classic compatibility trap — the hands will bind or press against the crystal. Confirm the case listing explicitly says NH34/GMT compatible.
Skeleton builds use a different family entirely — the NH70/NH71/NH72 with 30.8mm dials, covered in our skeleton movement guide.
Before You Order
- Pick the complication you actually wear (date? day-date? GMT?)
- Confirm the case says the movement name, not just "NH compatible"
- For GMT: verify explicit NH34 clearance
- Order dial, hands and movement as a matched set from one source when possible

Frequently Asked Questions
Is NH36 more accurate than NH35?
No — same architecture, similar factory tolerances. Regulation decides.
Can I swap an NH36 dial onto an NH35?
Only with an NH36 movement — the day-date dial needs the day wheel underneath.
Why is the NH34 more expensive?
Fewer are made and GMT demand is high; the extra hand stack also costs more to produce.
