Lug Width
The lug is where the strap meets the case of the watch and the lug width is the distance between the left and right ‘lugs’. Typically this is in the region of 18-24mm but straps come in all shapes and sizes
Buckle Width
This is the inside measurement of the buckle width where we will attach either your current buckle or a new one. I also supply buckles so I can recommend a taper (from lug to buckle) or use your current sizes
Sizing Guide
For a size guide please reference the below and also note that you can simply contact me for any advice at all:
- 6.1 - 6.5″ wrist (154 – 165mm) = 110/65
- 6.6 - 7″ wrist (167 – 177mm) = 120/70
- 7.1 - 7.5″ wrist (180 - 190mm) = 125/75
- 7.6 - 8″ wrist (193 - 203mm) = 130/80
- 8.1 – 8.5″ wrist (205 - 215mm) = 135/80
- 8.6 -9″ wrist (218 – 228mm) = 140/85
- 9.0+″ wrist (229mm+) = 145/90
There are two parts to the strap, the long part which has the buckle holes and the short part that has the buckle attached. Using the table above that shows Long side/Short side, so for example 120/70mm
If you want to replicate an existing strap I need the length of each side, typically the standard size is 120/70mm which tends to fit the average sized wrist as an example
To measure this the easiest thing to do is measure a strap that you may already have that fits perfectly and send me these, or alternatively measure the circumference of your wrist with a tape measure or a piece of string to then measure and send me that figure and I can recommend
Measuring lug, buckle and length can simply be done with a ruler, but for more accurate measurements I suggest getting some digital callipers online which are very cheap but remarkably helpful if you think you’ll use them again in future. I couldn’t be without mine now!
CTS Rubber Straps
Our CTS Rubber Straps are very easy to size, but there is a simple rule to follow - 'check, and check again', the famous 'measure twice, cut once'
The straps you receive fit the maximum wrist size out of the packaging. It is down to you to cut these to suit your wrist size using either a pair of sharp scissors or a sharp blade/crafting knife
We recommend working slowly, cutting a link off at a time. Work down to a point where you have more than you think you need.
Using the image you see in the guide, you are working down to meeting the ends of the rubber so they touch in the centre of your wrist. Cut down so you have more than you need initially and then attach the clasp and test the fit, then adjust as necessary. Every customer will require a different fit, loose or tight, so work to a fit that works for your wrist
You can if you wish cut the straps unevenly if you want to move the clasp to the centre of the wrist, or off centre as you wish
* Please note that these are non refundable if you have cut the strap incorrectly
Belt Sizing
Take your favourite belt and measure the distance from the base of the buckle where it connects to the leather to your most used hole, in inches
If you do not have a belt to hand simply take the waist size of your favourite jeans and add 2 inches to their waist size
Any concerns please email us to avoid disappointment as our belts are made to order and non refundable
