Watch Case Radial Lug Gauge 8-25mm – Measure Watches For Proper Strap Sizing

Radial Lug Gauge — Accurate Watch Lug Width Measuring Tool (Single Unit • Multiple Colors Available)

Get the right strap every time.

The Radial Lug Gauge is a compact, 3D-printed tool designed for watchmakers, dealers, and collectors to quickly measure the lug width of any wristwatch — so you can choose the perfect strap without guessing.

Simply slide the gauge’s tabs between the lugs. Each tab is clearly marked in millimeters, giving you an instant, precise reading. No calipers needed, no mistakes, no returns because “the strap didn’t fit.”

In the photos, we demonstrate measuring the lug spacing of a vintage Crosby wind-up — the gauge makes it simple and repeatable.
