The movementTime Module NH35, in plain words
The movement, in plain words
Octopus Kraken lists the NH35 for the OCT018.
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, 12.5 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. The lug span ends 4.1 mm inside each model edge.
Wrap a strip of paper round your wrist just below the bone, mark where it meets and measure it.
How tall it stands
The side view uses listed dimensions. Case shape and lug curve are schematic.
