Lug Width Matters
Lug width is the distance between the two lugs on your watch case. It determines which straps and bracelets fit your watch. Wrong width = strap falls off or does not fit.
Common Lug Widths
| Lug Width | Typical Case Size | Funny Items Models |
|---|---|---|
| 18mm | 31mm-34mm | 31mm Case |
| 20mm | 38mm-42mm | 39mm Case, 40mm Sub |
| 22mm | 43mm+ | 43.5mm Case |
How to Measure Lug Width
- Measure the inner distance between the lugs in millimeters
- Or measure the strap width where it connects to the case
Strap Compatibility
Always match the strap width to the lug width. A 20mm strap will not fit an 18mm lug. See: Watch Straps
