The movementSeiko NH34 GMT, in plain words
The movement, in plain words
Milifortic lists the Seiko NH34 GMT for the S103 Alpinist GMT. It is an automatic, so wearing it winds it.
On your wrist39.5 mm across, 12 mm thick, on a wrist your size
How it sits on your wrist
Set your wrist circumference to compare the 39.5 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 5.1 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.
