The strap width in respect to it's use on our website, always refers to the width of the strap at the end that connects to the watch, the spring bar or LUG end of a watch. We reference this end, as this is critical in selecting the correct width strap for your watch.
The width of the strap you select, should always match up with the distance between the LUG's on your watch case (refer image below). You can usually locate the width of your watch LUG's on the manufacturer's or retailer's website from where you purchased your watch. Alternatively, (and probably quicker) simply measure the distance with a ruler (again refer image below).
If you are still a little unsure on which size to choose, please contact us through our contact page and we will be more than happy to assist you.
