Strap Sizing Guide

Leather Straps

  • Regular Length 120/75mm fits wrists approximately 6 1/2" to 7 1/2", in 7 increments.
  • Short Length 105/70mm fits wrists approximately 5 3/4" to 6 3/4", in 7 increments.
  • Long Length 135/80mm fits wrists approximately 7 1/4" to 8 1/4", in 7 increments.

NATO Straps

  • NATO straps fit wrists approximately 5 3/4" to 9", in 13 increments. 11" / 280mm overall length.

You can easily measure your wrist size using a cloth tape measure. In a pinch, you can cut a rubber band or a piece of string, wrap it around your wrist, and mark where the two ends meet with a marker. Then lay the piece out flat and measure the distance from the end to your mark. This measurement will give you a good idea of your wrist size.

It is important to note that all measurements above are approximate and they are dependent on the size and lug design of your watch, as well as your personal preference for strap tightness on the wrist. All measurements are taken from an "average" sized watch head; 40mm in diameter, with a 47mm lug-to-lug distance. The wearable size will vary in direct relation to the watch size. Given the same strap length, a larger watch size will allow it to be worn on a larger wrist versus if it were on a smaller watch.


Whenever you see us referring to the width of a strap on this web site, we are talking about the width at the spring bar ends, where the strap meets the watch. Watches come in all shapes and sizes, and thus the width of the strap/band can vary as well.

As you can see in the diagram below, the width of the strap will correspond to the distance between the inside of the lugs on the watch head. If you do not know the width of the lugs on your watch (which can usually be found online at the manufacturer's or watch retailer's web site), then you can measure the distance with a ruler or a caliper. If you are not comfortable doing so, please contact us and we will help you find the proper size strap for your watch.

If you happen to have a watch that has an odd-numbered lug width, such as 19mm, 21mm, or 23mm, 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 lugs of your watch, for a fit that won't leave a gap between the lugs. Going a size down also works, as most straps run a little bit wide (i.e. 18.2mm, 20.2mm, etc.). However, this will usually leave a small gap between the strap and the lug of the watch.

If you are still having a hard time deciding which width or length would be best for you, please do not hesitate to contact us. We will gladly help you get everything figured out.
