This guide includes everything you need for measuring lug width, buckle width, strap length and wrist circumference
How we measure an existing strap
Measure (in millimeters): A, B, Short and Long side of the strap indicated in the diagram below.
A = Lug Width, B = Buckle Width, E = Strap Thickness
Getting fitted for a new strap
Measure (in millimetres): A, B, C and D indicated in the diagram below
A = Lug Width, B = Buckle Width, C = Case Width, D = Wrist Circumference
Choosing the correct strap length
Look at the size chart below and choose the correct strap length for your measurements. For example, if my wrist circumference is 150mm and my watch case width is 20mm, then the strap length i should select is 110/70mm. If you are in between sizes, choose the larger size.
(C) Width of the case (Distance between the case pins)
