Watch Strap Size Guide

Find You Ideal Strap Size In Minutes

Finding the perfect fit shouldn’t be a guessing game. Whether you are refreshing a classic timepiece or upgrading your daily diver, getting the lug width right is the most important step for both comfort and style. This quick guide will walk you through the simple process of measuring your watch so you can shop our collection with total confidence.

How Do I Find My Perfect Strap Width?

Please refer to the guide below to find the correct strap width for your watch. Using the wrong size can lead to a loose fit or even damage your watch lugs.

Perfect Fit Check List:

• Measure Exactly: Our straps are true-to-size. Order the exact millimeter width your lugs measure.
• Zero Mark: Always align the “0” mark of your ruler (not the physical edge) with the inside of the lug to ensure accuracy. A 1mm error can result in the wrong size or poor fit.
• Trust the measurement: We stock 19mm and 21mm widths. If your watch measures an odd size, order that exact width. There is no need to size up or down.
• No half sizes: Most watches use even numbers; if you measure 19mm, look for a specialized 19mm strap rather than squeezing in a 20mm.
• Buckle Taper: If you plan to reuse your original buckle, check the “Buckle Width” in our product specs, as many straps taper toward the end.
• Hardware Included: Every strap comes with a fresh set of spring bars. Quick-release straps come with bars pre-installed, while standard straps include a pair of regular spring bars for a secure fit.

— A precise measurement ensures your watch stays securely on your wrist and looks proportional.

Common Size Guide

If you don’t have a ruler handy, many brands follow standard sizing conventions based on the watch style:

• 18mm & below: Common for vintage pieces and smaller women’s watches.
• 20mm: The industry standard for most modern dress and sport watches.
• 22mm: Typically found on larger divers, chronographs, and pilot watches.
• 24mm & above: Reserved for oversized or “extra-large” tactical timepieces.

— While this chart is a helpful guide, we always recommend measuring your lugs to ensure the size is correct.
