DETERMINING STRAP SIZE
The size of our straps are determined by the distance between the lugs of your watch. Luckily, finding that measurement is easy. You do not have to bring your watch to a watchmaker to figure that out.
Using a millimeter ruler, simply measure the distance between the tip of your watch or the width of your existing strap (See picture above).
This measurement is known as the lug width and will be useful in helping you pick out the correct size when buying your watch strap.
