How to Measure


An easy way to determine the appropriate watch band size consists in measuring the width and length of your current watch band by using a metric tape measure or a millimeter ruler. If it's a leather watch band, you may also check the reverse side: the lug width is often imprinted into the lining leather. For higher accuracy, we recommend measuring both the lug width of the watch case (Fig. 1) and the buckle width (Fig. 2) by using a digital caliper.

When measuring the length of your current leather watch strap (Fig. 3), be sure to measure the hole part and the buckle part without the actual buckle. The hole part, minus the distance between middle hole and band tip, plus the buckle part, plus the watch case diameter, should be equal to your wrist circumference.

In order to determine the appropriate length of a metal bracelet (Fig. 4), first measure your wrist circumference with a metric tape measure, then subtract the watch case diameter from it. Another procedure would be to remove your current metal bracelet from the watch case, and to measure its total length in a flat position.
