The movement, in plain words

Steeldive lists the NH35 for the SD1970.

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 wrist43.8 mm across, 13.5 mm thick, on a wrist your size

How it sits on your wrist

Set your wrist circumference to compare the 43.8 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 78% of that estimated width. The lug span ends 4.6 mm inside each model edge.

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