How to determine what size watch strap you need:

All our straps are measured in millimetres.  You will need to know two dimensions: The width of the strap and the length.

​

Width

The width of the strap is the distance between the lugs, where the strap attaches to the watch. To determine the width, you can take a ruler or caliper, and measure the width of the part of the strap that uses spring bars / screws to attach to your watch case.

 

Measure this in millimetres.  Width is expressed, for example like this: 22/20 (22mm wide by 20mm wide). This first number (22mm) is the width of the strap between the lugs of the watch case. The second number (20mm) is the width of the strap at the buckle. This strap would be a "tapered" strap.

​

A “parallel” strap (sometimes known as "uniflow") is one that is the same width at the lugs and the buckle, i.e 22/22 (22mm wide at lugs by 22mm wide at buckle). 

​

Length

Two lengths are required, the tail end (the length of the long section with holes in it), and the buckle end (length of the short section, excluding the buckle).

 

Length is expressed, for example like this: 120/70. The first number (120) is the length in millimetres of the tail end with holes. The second number (75) is the length in millimetres of the end with the buckle.

​

The strap length suggestion is based on wrist size. To determine the your wrist length, you can simply wrap a piece of string/thread around your wrist at the point where you normally wear your watch, mark the string where it crosses itself, lay it flat on a table and measure the distance between the marks. This is your wrist size.

​

The list below will help to guide you as to which length to order.

​

6.0 - 6.5” wrist (150 - 164mm) = 120/70mm
6.6 - 7.0” wrist (165 - 178mm) = 125/75mm
7.1 - 7.5” wrist (179 - 190mm) = 130/80mm
7.6 - 8.0” wrist (191 - 203mm) = 135/85mm

 

If you are ordering a replacement strap and still have the original, you can always take the measurements from that. (NB if you measure from the head of the strap to the hole that you use and let us have this additional measurement we can make sure it is exactly the same.)
 

Choosing your strap length is all personal preference. There is no “right” or “wrong” in choosing the right length for you. A length that some might consider “too short”, or “too long” might be “just right” for you.  Strap length beyond the ability of it to hold your watch on your wrist is all down to how it looks and feels to you.
