Watch case size and strap fit, explained
A watch that fits looks right and stays put. Two numbers decide most of it: the case diameter and the range the strap adjusts to.
Measure your wrist
Wrap a soft tape measure, or a strip of paper you then lay against a ruler, around your wrist just above the wrist bone, where a watch usually sits.
Keep it snug but not tight. That number is your wrist size; compare it with the strap fit range listed on the product.
What case size means
Case size is the diameter of the watch case in millimeters, usually measured without the crown. It is the main number that decides how large a watch looks on the wrist.
There is no fixed rule, but mid-size cases in the high 30s of millimeters are a common everyday choice. Lug-to-lug length, from the top strap attachment to the bottom one, also matters: it should not overhang the edges of your wrist.
Leather strap fit
Buckle straps adjust through a series of holes, so they fit a range of wrist sizes rather than one size. Check that your wrist sits inside the listed range, ideally not at either end.
Leather softens and shapes to the wrist with wear. Keep it dry, since water can stain and stiffen leather.
How the Line Watch measures
The Line Watch has a 38 mm round case, quartz movement and a tan leather strap listed to fit wrists of about 6.3–7.8 in.
No water-resistance rating is published for this preview style, so treat it as a watch to keep dry.
