#1 - Use a standard ruler that offers a Centimeter side. Always measure in Centimeters as Inches are too large for an accurate conversion to Millimeters.

#2 - Measure the space between your watches lugs. (see red line labeled "Inner Space" in image)

#3 - Once you have the measurement in Centimeters, move the decimal one place to the right to convert your measurement into Millimeters. In the image above, you can see that the lug measures 2 Centimeters, which converts to 20 Millimeters.
