Watch Strap Sizing Questions
Take a ruler or caliper and measure in millimetres the distance between the lugs of your watch where the strap connects. Also, the lug width size can be easily found by doing a quick Google search for your specific watch model.
You can simply measure your wrist with a tape measure or a piece of thread. With the thread option, wrap it around your wrist at the point where you would normally wear your watch. Then, lay the thread out flat and measure the distance from the end to your mark on the thread. Next, refer to the length size chart below and choose the size that corresponds with your wrist measurement.
If you measured your wrist and it turns out, for example, that your wrist is exactly 7" which falls at the end of the 6.6" - 7" size range, then definitely choose the strap size that your wrist measurement corresponds to in our size chart below, which in this case would be 125/75. There's no need to go up a size.
If you have any doubt about which length is right for you, please contact us before purchasing for help. We'll be happy to assist you.
If your watch uses odd number lug widths like 19, 21, 23 and 25mm wide straps, we can easily make those widths for you as a parallel width strap. However, we do not supply buckles in those exact odd number widths as they are difficult to source. You will receive the next size up. So if you order a 21/21mm strap, you will receive a 22mm buckle with your strap.
Tapered straps start out wider at the lugs (the end that attaches to your watch) and narrow (taper) toward the direction of the tail and the buckle. So for example, if your Rolex Sumbariner has a 20mm lug width and you want a tapered strap, then you would choose a 20/18 strap. This means the lug is 20mm wide and the buckle/tail width is 18mm. Keep in mind that the higher number is the lug width and the smaller number is the buckle/tail width.
Below are the width sizes we taper our watch straps:
