OnWrist guide

Will this watch suit me?

OnWrist is a free visualizer for comparing case, lug-to-lug and strap dimensions before you choose a watch.

OnWrist wrist width, circumference and wrist tone controls

Set your wrist width.

Open Wrist width and match the visible width of your wrist. The circumference shown beside it is an estimate.

Use − and + to adjust the width in 0.1 cm steps.

Customize it your way.

Open Custom, then move through Case, Bezel, Lugs, Strap and Crown to build the silhouette.

Use the side arrows to change each part's style.
Fine-tune the dimensions in millimetres.

Refreshing, closing the tab or returning later clears them. Save the image or copy the settings link first.

Common questions

Is case diameter or lug-to-lug more important?

Both matter, but lug-to-lug is usually the better first check for overhang. Diameter controls visual scale, while lug shape and curvature decide how the case meets the wrist.

Can wrist width predict circumference?

Only approximately. Wrist cross-sections vary from round to flat, so two wrists with the same circumference can have different visible widths.

Is an online visualizer exact?

No. OnWrist is a proportion estimate, not a replacement for trying on the actual watch. Screen scale, case thickness, crystal shape and real lug curvature all affect the final fit.

Why can two 40 mm watches look different?

A wide dial, thin bezel and long straight lugs make a watch appear larger. A thick bezel, compact dial and short curved lugs make the same diameter appear smaller.
