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.
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.
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.

Introducing the Ribbed Mako FN watch strap. Inspired by the formidably fast Mako shark, scientifically the unique binomial nomenclature of Mako foe nay-dough.
Built to stand apart, the Ribbed Mako FN features the same bold ribbed nylon weave as our Ribbed Single-Pass strap that adds depth and character, a third "faux: keeper that nods to the double-pass military look, a long tail for tucking, an extra sturdy buckle and tongue seen on our AlphaShark straps, and precision oval heat-sealed adjustment holes to minimize fraying over years of wear.
A great complement to most every watch from toolsy sport and dive watches to slim minimalist pieces and classic field watches.
Fit Details: The Ribbed Mako FN watch strap is designed to comfortably fit wrist sizes from 6.25" to 9.75". Fit may vary depending on how tight or loose you prefer to wear your strap and the size of your watch. For wrists between 6.25" and 8.5", there will be enough length to tuck the strap under both keepers. For wrists above 8.5", the strap will stay secure under the keepers, but won’t have extra length for tucking.
This versatile strap pairs effortlessly with nearly any style of watch, from rugged Field Watches built for the outdoors, to Dive Watches designed for underwater adventures, Pilot Watches with their aviation-inspired functionality, Minimalist Watches that emphasize clean and simple design, Sport Watches made for high activity and performance, and Classic Tool Watches that blend durability with timeless style.

Great strap, it’s longer than I thought but it’s also because of the lug to lug. Overall great strap, and will definitely buy different colors for other watches
I was looking for the perfect nato strap for my vintage Glycine Airman. I wasn't sure what style/colors would look best, so I bought a few. Some from BluShark, some from other companies. The idea was to rotate the straps, but once this one got on, it never came off. It feels amazing on my wrist, the perfect tension with just slight give for maximum comfort and stability. And it looks amazing.
You guys are simply the best supplier of watch bands. My Bond strap is beautiful and with great stunning quality. Makes the watch Pop! Bam! Transformation complete. Regards David

Hey Nicholas,
That's definitely not supposed to be happening! Please do respond so we can get this figured out for you ASAP. This could be a faulty spring bar, but from the photo, it looks like the strap might not be fitting properly between your watch lugs, which is a bigger concern.
Either way, we can get you a replacement strap or help find a size that fits your watch better.
Just let us know, and we'll get this taken care of for you!
Great strap quality, reasonable prices, and super-fast shipping. I will be back. Thanks!
Great looking watch strap. Using on my Tissot Seastar 1000. The colors are great. The quick connect is great because it keeps the profile of the watch closer to my wrist. I would recommend.
Really happy with the two-piece Mako strap. It’s comfortable, well made, and most importantly, it works well on a sub-7-inch wrist. The watch sits flat and centered on the wrist without the extra bulk you can get from a traditional nato strap.
The strap is well made
The hardware is nice
The colors are nice the strap just doesn't work for me
If you like them reach out to me I will be happy to move them to someone who will use them
At the same time I purchased a dark tan and maroon strap neither of which I will use.
Thay are nice they just do not work for me
I had just recently bought a new Certina 40.5 DS Action Diver and had ordered the 2 part Nato strap and loved that one. After seeing how great it looked, I wanted to try the Single Pass Nato on my Citizen Diver, and I love it. The original 2 piece wouldn't fit my Citizen but I loved the look so much I went with the Single pass and it fits and feels incredible. I have purchased multiple bands from BluShark and you can't beat the quality and finish, not to mention the great discounts they offer. I am a true fan of BluShark!
This is now my go to brand for watch bands! Super good quality! Fast shipping. I love the easy to install and remove bars that are included with the bands. 100 percent recommend!
The strap was good and I like that it has the quick attach/remove, just that I expected the strap to be more thick and heavy duty, but it's still quality nonetheless
Great strap! Nice and breathable for the summer without the extra material of a normal NATO. I really like the army green color on this one and It looks great with my red bezel Alpina Seastrong diver.

Love to hear this! Thanks, Chris. Glad you're loving the new strap!
I’m really liking these ribbed Mako straps! Gives the look and feel of a nato without the extra material. This one looks great with a bunch of watches, especially my brown/tan Alpina Seastrong. Feels very well-made and is probably my new favorite strap for thicker watches in the summer.
These straps are awesome! Gives the look, feel and breathability of a nato without extra material underneath the watch case. This one in particular looks great with my Seiko Samurai among others. Hardware and construction are solid. Feels very well made.
