It’s proven to be a revolutionary material for bracelet function - the strap is water resistant up to 300 meters, hypoallergenic, resists wear & tear and has an integrated moisture and thermoregulation system. The soft caoutchouc core is flexible, adapting to the shape of the wrist and the groove structure on the underside ensures humidity and water are quickly released, creating an immediate drying effect.

Watch Band Measuring Quick Guide

How To Find Your Watch Band Size

Watch band or watch strap size is determined by the width of the band end that attaches to the watch. If you already have a leather band for the watch in question, you can check the back to see if it has a size imprint, shown in millimeters. Otherwise, you will need to find the lug width (distance between the inside of the lugs on the watch head). You can easily measure it yourself in one of the below three ways.

Rounding: Rule of thumb for a replacement watch band is that it’s better for the watch band to be tight rather then loose. If you need to round your measurement, rounding up is usually your best bet. A leather, rubber or nylon watch strap can be slightly flexible to fit.

How To Find Your Watch Band Length


Method 1: Measure An Existing Strap that fits your watch with a ruler to determine the length. When measuring, only measure the material parts of the strap, do not include the buckle.

Method 2: Finding Length From Scratch
1) Find yourwrist size by wrapping a tape measure or a piece of string around your wrist. Mark where the two ends meet then lay the thread out flat on a ruler and measure the distance. Find your watch head size by using a ruler or check the manufacturer for information.

2) Minus yourwatch head measurement from your wrist size measurement. This will give you the total watch band length needed.Important Note: Not all watch bands are manufactured in every length, and most metal watch bands are adjustable, so choose the size closest to your size or go longer.
