Disclaimer
An approximation of the NH35 layout from public drawings and photographs, not a manufacturer-accurate replica, shown with the NH36’s added day disc. The NH36 is described as the NH35 base with a day display (Caliber Corner); 24 jewels, 41 h, Ø 27.4 mm and 5.32 mm are listed for the NH36 by MN Watches. The rate (21,600 vph, 3 Hz) and the winding, hacking and date features are those of the NH35 base (TMI specification sheet). No NH36 drawing was found, so the day disc layout is an illustration. Tooth counts, the seconds drive and the exact shapes and positions of parts are an approximation. No source checked names the escapement type: the lever escapement shown is a generic illustration, and its motion is a kinematic model, not a physics simulation.
