| Calibre | Diameter | With spacer | Height | Calendar | Beat rate | Source |
|---|---|---|---|---|---|---|
| NH35A | 27.40 mm | 29.36 mm | 5.32 mm | date | 21,600 vph | Maker sheet |
| NH36A | 27.40 mm | 29.36 mm | 5.32 mm | day-date | 21,600 vph | Maker sheet |
Spacer dimensions are separate from the bare movement diameter. Height does not establish hand or rotor clearance. Only directly verified maker entries appear here; other calibres will be added after source review.
Worked example: NH35A to NH36A
Difference = destination dimension − original dimension. Diameter: 27.40 − 27.40 = 0.00 mm. Height: 5.32 − 5.32 = 0.00 mm.
- Published diameter matches (difference 0.00 mm).
- Published height matches (difference 0.00 mm).
- Calendar differs: NH35A has date; NH36A has day-date. Confirm the dial window, day wheel language and orientation.
- Dial feet and spacer compatibility are not established by these figures; confirm with the parts supplier.
- This is a comparison of published specifications, not a fit guarantee.
What this cannot establish
Case drawings, dial feet, calendar window positions, hand fittings and stem variants must be checked separately. Blank or unverified values are never treated as a match.
