The movementPT5004, in plain words
The movement, in plain words
Octopus Kraken lists the PT5004 for the OCT025. It is an automatic, so wearing it winds it.

How it sits on your wrist
Set your wrist circumference to compare the 37 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 66% of that estimated width. The lug span ends 5.3 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.
