Method 1: Measure from the Watch Case
Measure the width between the watch lugs in millimeters(mm). It is important to measure ONLY from the inside of the lugs as shown in example 1.
Inaccurate readings could lead to not fitting or a loose fitting (You will see gap between the watch strap to the watch). We do recommend to use a pair of vernier calipers if not a ruler to take the measurement.
Method 2: Measure from the Watch Strap
Measure the width at the END of the watch strap as shown in example 2.
