On your wrist40 mm across, on a wrist your size

How it sits on your wrist

Set your wrist circumference to compare the 40 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 71% of that estimated width. Lug to lug is unknown, so no lug extent is drawn. Thickness is unknown, so no case height is drawn.

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

What owners report

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

From owners1 report

  • One-week owner found the 40 mm Phylida wore larger than his 42 mm Omega on a 6.25-inch wrist. Nearly 15 mm height, weak lume, reflections and untapered bracelet limited fit; chrono start/stop worked but reset felt soft.
