Strap Sizing Guide




Strap Width

Watches come in all shapes and sizes, and might use a strap as narrow as 12mm, or as wide as 28mm. Identifying the correct size needed for your watch is simple, and will ensure the perfect fit.

The width of a watch strap (given in millimeters) corresponds to the inner opening of the watch "lugs," known as the lug width. The lug width for any given watch can typically be found online on the manufacturer's or watch retailer's website. Likewise, you can measure the lug width easily using a caliper or a household ruler, which usually has a millimeter scale.

If you happen to have a watch that has an odd-numbered lug width, such as 19mm or 21mm, you are not out of luck. Our advice is to buy the next size up. The leather or nylon is pliable enough that you will be able to squeeze the larger strap between the 1mm smaller lugs, for a fit that won't leave a gap. Going a size down also works, as most straps run a little bit wide (i.e. 18.2mm, 20.2mm). However, this will usually leave a small gap, which is more noticeable.

* Black Label and American Made two piece straps are 115/75mm, but fit the same due to their thinner designs.

You can easily measure your wrist size using a cloth tape measure. Alternatively, a piece of string can be used. Wrap the string around your wrist, and mark where the two ends meet with a marker. Lay the piece out flat, and measure the distance from the end to your mark.

Note: The approximate range of wrist size fitments listed above are as measured using an "average" watch: 40mm case, 47mm lug-to-lug distance. The wearable size of a strap will be affected by the size of the watch, the shape of the lugs, the thickness of the strap, and your personal preference for tightness.
