Finding the perfect strap or accessory for your watch can greatly enhance comfort and style. Our sizing guides help you measure your watch accurately, ensuring the best fit. Whether you have a traditional watch or an Apple Watch, we provide step-by-step instructions to determine the ideal strap size and watch lug width. With these guides, you can confidently choose the perfect straps and accessories to enhance your watch.

• Traditional Watch Instructions:
1) Open Our Sizing Guide Here. Download Here
2) Print File. In print options dialogue box, uncheck any “shrink oversized pages to fit” or “fit to page” boxes. *IMPORTANT!*
3) After printing, test the accuracy by measuring the “one inch” test strip with a standard ruler.
4) Cut off the inch ruler from the side and wrap around your wrist to determine your wrist size.
5) Hold your watch with the lugs framing the blocks below to determine your lug width. There should be no gap or overlap.
Lug Width Measurement:
To determine your lug width, print the BluShark Watch Sizing Guide in step-1 and place your watch on the measuring blocks located on the bottom of the guide.

2) Print File. In print options dialogue box, uncheck any “shrink oversized pages to fit” or “fit to page” boxes. *IMPORTANT!*

3) Cut out the tool. Position the wider end where you would wear a watch. For a more accurate measurement, you can use a piece of tape to hold the wider end in place.
4) Wrap the tool around your wrist, keeping it in place. Make sure the tool feels snug and doesn’t slide up or down.
5) Note the inch number the arrows point to – that’s your band size.

6) If the arrows land between two measurements, choose the smaller of the two numbers closest to the line.
Adapter Measurement:
To determine which size adapter you need, use the following guide:
If your Apple Watch is 42mm, 44mm, or 45mm, you’ll need an adapter that measures 22mm.
If your Apple Watch is 38mm or 40mm, you’ll need an adapter that measures 20mm.
If you have a 41mm Apple Watch, choose the 20mm adapter.
Unsure of your case size? You can usually find it on the back of your Apple Watch, near the sensor. Or, open the Apple Watch app on your iPhone, go to "My Watch" at the bottom, then tap General > About.

The Sailcloth Two-Piece Watch Strap with added Apple Watch ULTRA adapters is the perfect strap to compliment your Apple Watch! It's a solid everyday option that balances comfort, durability, and style. Whether you're out for a light jog, taking a quick swim, or just going about your day, this strap is built to keep up. It has a classic look that works well with just about any watch—whether you're wearing something sporty or a bit more dressed up.
Each strap is stitched around the edges, which not only gives it a clean, finished look, but also helps hold the material together for the long haul. On the outside, you’ve got a rugged sailcloth surface that can take a beating, and underneath there's a waterproof rubber liner that feels soft and smooth against your skin. It's easy to clean and handles water and sweat without a problem.
Material: Our sailcloth watch strap is made from durable PVC rubber, embossed with a sailcloth-style pattern that adds just the right amount of texture and character. It strikes a great balance between rugged and refined—tough enough for everyday wear, but with a clean, stylish look that works just as well with a dress watch. The rubber base makes it water-resistant and easy to maintain, while the patterned finish gives it a unique, modern edge.

The Color: Gray with Gray Stitching. This strap’s gray hits that perfect middle ground—not as bold as black or blue, not as light as tan. It’s the kind of color that works with just about anything without fading into the background. The matching stitching blends in just enough to keep things looking clean and refined. Flip it over and you’ll notice a black waterproofing liner. The result? A sleek, upscale finish that adds a polished touch to your watch without trying too hard.
