A case advertised as “for NH35” is not verified by the seller title alone. The reference is a useful starting point, but it must be checked against the geometry and configuration of the build.
Check that NH35 is stated explicitly
An explicit mention shows the compatibility claimed by the seller. It is commercial evidence, not an absolute technical guarantee. Always check the selected variant and full description.
Check the movement cavity
The manufacturer drawing provides dimensions for the movement and the specified spacer assembly. These figures help rule out options, but one matching dimension does not prove that a case fits.
- Outside movement diameter
- 27.4 mm Manufacturer data · TMI
- Diameter with specified spacer
- 29.36 mm Manufacturer data · TMI
- Movement height
- 5.32 mm Manufacturer data · TMI
- Crown position
- 3H Manufacturer data · TMI
- Complete cavity geometry
- Spacer being used
- Available internal height
- Retention system
- Actual crown and tube position
Check the supported dial
The TMI NH35 drawing shows a 28.5 mm dial. The dial's outer diameter and the visible or supported case opening are not necessarily the same measurement.
Check the dial seat, rehaut or chapter ring, and every limit stated by the case manufacturer.

Crown and stem
The current specification places the NH35 crown at 3H. Confirm that the case, tube, crown and stem match the specific build configuration.
A case may mention NH35 while offering variants with another position or different components.
