The movement, in plain words

Steeldive lists the NH35 for the SD1940.

How it runs. An automatic. Wearing it winds it.

Beat. It beats 21,600 times an hour, 6 a second, so the seconds hand sweeps in small steps.

Setting the time. The seconds hand stops when you pull the crown out, so you can set it to the second.

On your wrist39 mm across, 12 mm thick, on a wrist your size

How it sits on your wrist

Set your wrist circumference to compare the 39 mm case with a schematic wrist. The ellipse estimates wrist width and shape. It cannot predict your fit.

17.0 cm6.7 in around

This wrist model is about 56 mm across. The case spans 70% of that estimated width. Lug to lug is unknown, so no lug extent is drawn.

Wrap a strip of paper round your wrist just below the bone, mark where it meets and measure it.

39 mm case Wrist model about 56 mm across
Schematic section, with a 10 mm grid. The ellipse approximates wrist anatomy from circumference. Your wrist shape, lug curve and fit will differ.

How tall it stands

12 39 wide

The side view uses listed dimensions. Case shape and lug curve are schematic.

Lug to lug is not listed yet, so the drawing stops at the case.
