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.

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.

That Classic Military-Style Look, Now For The Apple Watch ULTRA!
Our customers love the timeless look of classic military-style straps, but that design was never practical for Apple Watches since the strap material would cover the sensors underneath. The Ribbed Mako FN changes that. It delivers the same rugged double-pass aesthetic in a clever two-piece design that leaves your Apple Watch sensors fully unobstructed.
Introducing the Ribbed Mako FN watch strap. Inspired by the formidably fast Mako shark, scientifically the unique binomial nomenclature of Mako foe nay-dough.
A two-piece design that captures the rugged look of military pass-through strap with modern updates. Just like the Mako glides through the water with speed and precision, you can swap our straps quickly and effortlessly with the preinstalled adapters. Plus no added watch height that you'd see from a pass-through strap, and the freedom to show off your watch’s case back without removing the strap!
Built to stand apart, the Ribbed Mako FN features the same bold ribbed nylon weave as our Ribbed Single Pass that adds depth and character, a third keeper that nods to the double-pass military look, an extra sturdy buckle and tongue seen on our AlphaShark straps, and precision oval heat-sealed adjustment holes to resist fraying over years of wear.
