The movementSeiko NH38, in plain words

The movement, in plain words

Baltany lists the Seiko NH38 for the S4029 central-seconds Bubbleback. It is an automatic, so wearing it winds it.

How it sits on your wrist

Set your wrist circumference to compare the 36 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 64% of that estimated width. The lug span ends 6.1 mm inside each model edge.

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