Light Grey Nubuck Strap for Cartier Tank
Chat with us now
The Cartier Tank has cemented its positioning as one of the most iconic watches of the past 100 years, and its popularity is going strong today. We are pleased to offer straps to fit the modern day Cartier Tank Must and Tank Louis Cartier, in Small, Large and Extra Large sizes.
Nubuck has a soft touch with a short and even nap. It is supple and flexible from the start, but yet has just the right amount of structure. This strap is great if you are looking for something that's casual enough for all your daily activities, soft and comfortable to the touch, and an alternative to regular leather texture.
Note: These straps will also fit other Cartier models, as long as the lug width is the same. For example, the Tank Small strap will fit the Tank Cintree, which has a 16mm lug width. It will not fit the Tank Solo models, which come in different lug widths.
Note: Delugs is not affiliated with watch brands such as Cartier, and the strap was developed independently by Delugs. Intellectual property rights of watches, visuals, trademarks, names and logos belong respectively to each related watch brand.

Strap Length Calculator
- Place your watch flat (face up)
- Measure from the tip of the top lug to the tip of the bottom lug
- Use mm for best accuracy
- Wrap a measuring tape (or string) snugly around your wrist
- Measure just above the wrist bone
- Don’t add extra slack — choose the closest band
What determines strap length?
Strap length is primarily determined by your wrist size. Watch lug-to-lug and wrist shape can affect how the strap sits, but they do not change the standard strap length recommendation.
Between sizes?
If your wrist size falls between two ranges, we generally recommend sizing up for better comfort.
When should I consider custom length?
- Your wrist is outside the Small–Large range
- You prefer very short or very long tail length
- You’re pairing the strap with a deployant clasp
- You want a specific hole position or tail length
Example
A 16.8 cm wrist typically fits a Medium (115/70) strap. If you prefer a shorter tail, Small may also work — but Medium is the safer choice.
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 trusted online sources.
- Next, you can use a pair of callipers to measure your watch's lug width. Keeping in mind that different references under the same collection can have varying lug widths, it's always best to double-check.
- Alternatively, you can use a ruler to measure your watch's lug width. Make sure the ruler's marks line up with the inner edge of the lugs for the best accuracy.
If you're searching for a Delugs strap to use with a vintage watch, be sure to check in with our Customer Service. Vintage watches sometimes use odd widths (17.5mm) or have shallow spring bar plots. This can increase the likelihood of slippage, even with the correct strap installed. Our trained staff will advise on the best course of action for a perfect fit.
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.
Scratch-Resistant
Pliable
The strap is very soft and flexible, and is extremely comfortable with zero break-in required. This is owing to both the type of material used, and the overall construction of the strap.
Chrome Tanned
The animal hide is turned into leather through a tanning process that uses chromium salts and tanning liquors. Chrome-tan is a more industrial tanning process, and the resultant leather is typically more pliable, with greater water-resistance and scratch-resistance properties. Chrome-tanned leather are generally also available in a wider range of colours.
