Find Your Lug Width
If you're looking to purchase a strap for your watch, you will need to know the lug width of your watch. Lug width refers to "A" in this schematic below.
There are two ways to find out the lug width of your watch.
- Firstly, you can Google "<watch brand and model> lug width" and see if there is an answer from the brand's website, or some other websites.
- Alternatively, you can simply take a ruler and measure the lug width directly on your watch.
Lug widths are typically in whole numbers, and while the most common lug widths are between 18-22mm, they can go down to 8mm or up to 32mm even. Our ready stock straps are available in 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 24mm and 26mm. If you need other lug widths, you can have it custom made.
You will then need to purchase a strap of the same lug width. For example, if your watch has a lug width of 20mm, you will need to purchase strap with a width of 20-16.
Note: Our Widths typically have two numbers, for example 20-16. The first number (20) refers to the lug width ("A" in the schematic above). The second number (16) refers to the buckle width ("B" in the schematic above). You just need to ensure that the first number matches the lug width of your watch.
Cut-To-Size
The strap comes in one length, and can be easily trimmed down to fit any wrist size, for a comfortable, secure fit.
Waterproof
The material and construction is waterproof, and the strap can be soaked in water for extended periods.
Rubber Lining
The strap is crafted with a rubber lining, for increased sweat resistance while worn on the wrist.
Clasp Option Guide
Amazing strap with top quality!
My second rubber strap. High quality and quick delivery. Ordered Monday and received it Wednesday in Denmark, Scandinavia
Had an issue with the lug width and they were able to assist me in a professional manner.
・The fkm strap was softer than I expected.
・The clasp takes some getting used to, but it's one of the best third-party butterfly clasps available.
・If the buckle had at least three holes, it would be possible to make more precise adjustments.
・The website does not sell the clasp for the CTS strap separately, so it is currently not possible to purchase a spare one.
Thanks so much for taking the time to share your thoughts – we really appreciate it!
Great to hear the FKM strap felt softer than expected. That flexibility is a natural trait of the rubber we use and helps make it extra comfortable on the wrist. We're glad you consider our butterfly clasp one of the best! It can take a little getting used to at first, but it becomes second nature quickly.
And just to clarify – the CTS Deployant Clasp is available separately! You can find it here: https://delugs.com/products/cts-deployant-clasp

What a quality rubber strap. Super comfortable and very easy to install after the difficultly removing the existing Longines bracelet. Looking forward to my next Delugs purchase!
