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.

I actually ordered the wrong size sailcloth rubber deploy band for my Apple Watch Ultra. Customer service was great, offering an easy refund, but I decided to keep the strap and use it on my Apple Watch Series 7 and order another strap for the Ultra.
The quality and look of the orange sailcloth rubber deploy band is better than anything I have seen from other manufacturers. I can't wait to get a band for my Ultra!
I highly recommend considering Blushark for anyone looking for great straps at a great value! Thanks again Blushark!
This is my new favorite strap! I’ve always liked this style deployant, but pairing it with the fkm rubber is perfect! I’ve always liked the look of sailcloth, so that’s just a bonus. I will be ordering more for sure. Is this compatible with the big Seiko lug holes?
Love the quick change feature of this band. I am a fan of sailcloth and loop less deployant clasps on a band, and BluShark is a very high quality choice. I would definitely purchase from BluShark again for their quality, and great service.
I've been a Blueshark fan for years. I couldn't wait to get this on my modified GMT! Fantastic quality for an affordable price. Also appreciated the fast delivery.
These straps are amazing for the price. I ordered a strap form Artem and these honestly blow them out of the water. Way smoother and comfortable for a lot less. Highly recommend them for all types of watches.
This strap is a high quality upgrade to the factory rubber strap. Fast shipping too. Comfortable and no break in needed. I highly recommend Blue Shark and this strap fot those wanting an all weather upgrade to their sport watch.
Great product! This is the one I used daily with my SBSC009. The only issue I have on it is that my hands are probably bigger than most so sliding it into the band is quite cumbersome.
I now have 4 reply bands of different colors. They are so easy to put on and take off. I wear them for everything from tennis, gym to cocktail parties. They look great. The black especially with the dark ultra watch.

Hey Lewis,
Really sorry to hear you’re not a fan of the Sailcloth Rubber Deploy. We’d be happy to set up a free exchange if you feel another band in our collection would be a better fit for what you’re looking for.
Just let us know what you have in mind, and we’ll be happy to get the exchange set up for you!
The sailcloth surprised me with its durability and comfort! I work in very hot and cold environments and this band never changes its fit or becomes uncomfortable! I would highly recommend it for any application
Second FKM sailcloth from BluShark and again one of the most comfortable straps i own. The orange absolutely pops and the FKM rubber stays clean. Deployant clasp is fantastic, definitely getting more colors.
Absolute chefs kiss here. Super comfortable to wear all day even in the heat we’ve had lately. 10/10 would recommend. Will be getting more for my other watches in the future
Very comfortable. I appreciate how easy it is to take off and put on my Ultra 3 with the deploy fastener.
I have ordered three more in different colors.
Threw my new BluShark strap onto my Breitling Superocean. Highly pleased with the strap. Quality exceeded my expectations for the price I paid. Fit and finish is great. Will definitely purchase a few more for some of my other watches!
Replaced my Samsung watch strap with this, and it's way better than the stock silicon. The clasp is solidly built and easy to adjust strap length once you figure out where to push/pull. The contrast stitching is very nice on this, despite being a rubber strap.
I like to wear my straps tight, and so far it's been very breathable & I sometimes forget I'm lugging a 45mm watch for the day. Strap's generally quick to dry and the clasp itself rarely retains water, but I've sometimes had to unclasp to properly dry it whenever it's humid.
Overall, a very good value deployant clasp strap.
