The movementTime Module NH35, in plain words

The movement, in plain words

Proxima lists the NH35 for the PX1683-BY.

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 wrist44 mm across, 15.8 mm thick, on a wrist your size

How it sits on your wrist

Set your wrist circumference to compare the 44 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 78% of that estimated width. Lug to lug is unknown, so no lug extent is drawn.

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.

Lug to lug is not listed yet, so the drawing stops at the case.

What owners report1 report on one topic

What owners report

Written reviews. Each covers one watch, so read them as things to check rather than a verdict.

From reviews1 report

  • Owner found curved lugs comfortable and polished corners smooth; their example stayed within three minutes over a week. That single sample result does not establish accuracy of current production.
