Watch Strap Size Guide

Choosing a replacement strap starts with a reliable measurement. Remove the strap if necessary and measure the distance between the inside edges of the watch lugs in millimetres. Record the result before comparing strap listings. The strap width should match the measured lug width; a difference can leave gaps or prevent the spring bar from seating safely.

Length and wearing comfort

Wrist circumference helps determine strap length. Short, regular and long options are useful starting groups, but padding, keepers, clasp position and personal preference also matter. Measure around the wrist where the watch will sit and compare that measurement with the product’s published strap length when it is available.

Evidence policy

DailyTime Store lists a strap as compatible only when the product record contains verified lug-width and strap-width information. Missing dimensions remain UNKNOWN. Do not treat a similar product name, photograph or movement as proof of strap fit. Contact support before ordering when the watch has unusual lugs, fixed bars or limited spring-bar clearance.

Use the calculator for a first recommendation, then review the product page and compatibility hub. This guide links to both so the measurement, product evidence and ordering decision remain connected.
