Intergrate Curved End - Matte Black alligator strap for Patek Phillipe Aquanauts

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.

1. 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.
2. 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 

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. 

Basic Sizing Guide

There are two sides per strap, which we refer to as the long end and the short end, which are represented by C and D respectively in the diagram below.

Our handcrafted leather straps come in 3 different lengths.

1. Small (C: 105mm, D: 65mm)
2. Medium (C: 115mm, D: 70mm)
3. Large (C: 125mm, D: 75mm)

A quick way to decide on the length to get is based on your wrist size. Here is the general recommendation (if you are between sizes, we recommend to size up):

• Wrist size of 14.5cm - 17.0cm: Small
• Wrist size of 16.5cm - 19.0cm : Medium
• Wrist size of 18.5cm - 21.0cm: Large

If you need a strap that is shorter than Small (105/65), or longer than Large (125/75), you can always have the strap custom made.

Advanced Sizing Guide

We are now running a trial on split size ordering. This is only recommended if you are more experienced with how leather straps wear on your wrist, and you know the specific length of straps that you require on both the long and short end.

For example, you might currently have a Medium size strap on your watch (115mm and 70mm), and you notice that the buckle sits in the middle of the wrist, but the long end of the strap is too long and can be seen when the watch is on your wrist. In such a situation, you may need a long end that's shorter than 115mm, but the buckle end of the strap should remain unchanged at 70mm. In this case, you might want to order 105mm/70mm instead of the standard 115mm/70mm.

If you are unsure what length you require for each side of the strap, we recommend sticking with the three standard sizes, Small, Medium and Large. 

Hope this quick guide helps! Finding the perfect length to get can be a little bit more complicated, as it also depends on the lug-to-lug distance of your watch, and even the shape of your wrist. For a more detailed guide on sizing, please check out this page.
