Technical Specifications

Installation Requirements

Ensure you have the following tools on hand before fitting the NH35:

• case-back opener
• movement holder
• hand-press

The NH35’s standard 1.00 mm hour-wheel cannon pinion and 0.20 mm hand-hole sizes ensure seamless compatibility with most aftermarket hands and dials. Stem length is factory standard but may be trimmed for custom case depths. Each NH35 movement ships uncased and freshly oiled and should be secured under a dust-proof, double-layer movement cover until fitted.

Date Wheel and Dial Positions

Date wheel installed at the 3, 3.8, and 4.1 o’clock positions.
