How to Measure Watch Band?

The easiest way to measure your watch band is to simply check the inside of your old band. Most straps have the sizes imprinted on the inside of the band. See Picture Below. Secondly, you can measure the band itself. Remove watch strap and measure the width of the top of the watch band. This is the side of the band that attaches to the case. Lastly, you can measure the distance between the watch case itself (lug to lug). See picture below. Most watch bands are measured in millimeter sizes.
