On some leather straps a size will be stamped on the inside of leather strap. A quick internet search of your timepiece reference number will provide technical information including lug width. You can also measure with a ruler the size you need, measure either your current strap width where it attaches to your timepiece or from lug horn to lug horn. Alternatively, you can send us a picture of your timepiece, front and back in great detail and we will assist where possible. Please send picture to rachel@amgstrap.com
