The movementSellita SW330-2, in plain words

The movement, in plain words

Christopher Ward lists the Sellita SW330-2 for the C63 Sealander GMT.

How it runs. An automatic. Wearing it winds it.

Beat. It beats 28,800 times an hour, 8 a second, so the seconds hand sweeps in small steps.

Off the wrist. It runs for about 56 hours once fully wound. Take it off on Friday evening and it will have stopped by Monday in the early hours.

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.

Wrist circumference

This wrist model is about 56 mm across. The case spans 70% of that estimated width. The lug span ends 5.2 mm inside each model edge.

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

Schematic section, with a 10 mm grid. The ellipse approximates wrist anatomy from circumference. Your wrist shape, lug curve and fit will differ.
