What Is The Lug Width & How Do I Measure It？
SwornerileeA Guide for Watch Enthusiasts and Strap Shoppers
If you’ve ever tried to replace or upgrade your watch strap, you’ve probably encountered the term “lug width.” But what exactly does it mean, and why is it crucial for finding the perfect strap? In this guide, we’ll break down everything you need to know about lug width and how to measure it accurately.
What Is Lug Width?
Lug width (also called “lug size” or “strap width”) refers to the distance between the two lugs on a watch case where the strap or bracelet attaches. These lugs are the small protruding arms on either side of the watch case (see diagram below).
The lug width determines the compatibility of replacement straps—if the strap’s width doesn’t match your watch’s lug width, it simply won’t fit. Common lug widths range from 18mm to 22mm for most watches, though sizes can vary depending on the style (e.g., dress watches vs. sport watches).
Why Does Lug Width Matter?
- Perfect Fit: A mismatched strap can damage your watch lugs or fail to secure properly.
- Style Consistency: The right lug width ensures a seamless, proportional look.
- Compatibility: Many straps are sold in specific widths, so knowing your lug size saves time and hassle.
How to Measure Lug Width in 4 Simple Steps
(No Tools Required!)
- Remove the Current Strap: Carefully detach the strap from your watch using a spring bar tool. If you’re unsure how to do this, check the watch’s manual or [link to a tutorial video].
- Measure Between the Lugs:
-
Use a Caliper (most accurate): Place the caliper jaws between the lugs to measure the gap.
- Use a Ruler (if no caliper): Align the ruler’s millimeter markings with the inner edges of the lugs.
Pro Tip: Round to the nearest millimeter (e.g., 20.5mm = 21mm). Most straps are sold in whole-number sizes.
- Check Existing Strap: If the original strap is intact, measure its width at the point where it connects to the lugs.
- Double-Check: Verify measurements across multiple sources (e.g., manufacturer specs, online forums) to ensure accuracy.
Common Lug Width FAQs
Q: My watch has curved lugs. How do I measure it?
A: Focus on the straight portion where the strap sits, not the curved ends.
Q: What if my measurement is between sizes (e.g., 19.5mm)?
A: Round up to the nearest whole number (20mm). Most straps have slight flexibility.
Q: Are all lug widths standard?
A: Most brands follow common sizes (18mm, 20mm, 22mm), but always measure vintage or luxury watches, as they may vary.
