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 needed a 24m sailcloth for a large watch of mine. I tried a few other "big brand name" sites and couldnt find a 24m size...hmmm, I thought...I kept looking and found Blue Shark. They had 24m size with deployment clasp! The price seemed fair enough, but you never know about the material until it arrives....when it arrives I was blown away! Not only is it a perfect fit with an adjustable clasp, but the material is just outstanding! I didnt take that watch off for 3 days, yes even at night, because it was so darn comfy. I am very impressed and the price is great! I like it so much so that im now looking for another 24m size for a new watch I ordered. Blue Shark has made me a believer. If youre on the fence dont wait, go for it, you wont be disappointed.
Three weeks ago I bought my first strap and liked it so much that I ordered a second one for another watch. The quality is great, and very comfortable on the wrist. Definitely recommend it.
Waited a couple of months for this strap to come back in stock, was excited to receive it, but the clasp marketed with "listen to that snap" is very loose and comes undone much too easily. I really like the strap, maybe a defect, but would love to receive a replacement.

Hey John,
That clasp definitely shouldn't come undone easily. I'll have the support team reach right out to get you a free replacement buckle!
The strap and clasp seem fantastic but it’s just to long. If there were one maybe two more holes it would fit. The other option is to either include a second shorter strap for people with smaller wrists or have an option. You know when you buy the strap to have one of two sizes I know another at least one other company that does that they include two straps other than that it seems great.
Very comfortable strap for my Tissot Seastar. Feels like a high quality strap and the orange stitching complements the orange dial on the Tissot. Fast shipping too - overall a great buying experience.
Very nice strap! I’m a big fan of the deployment clasps. Really happy how well the orange stitching looks. This is a great looking and comfortable strap!
Beautiful band, but I was expecting a 2mm taper, not 4mm. The picture in the listing showed a 20/18 stamp on the inside. Purchasing a 22 I was expecting a 22/20. I could have bought the exact same VVR strap at Strapco for substantially much less.
Great quality!! The clasp is very solid and secure . This strap has become my go to for daily wear . I can definitely see ordering feom blue shark again.
Looks great, fits great. I have smaller wrists, around 6.5 inches around, so I was worried that the strap would be too large. It fits at the 2nd/3rd smallest hole, with one more size to go down. There is little bit of play with the buckle, but nothing significant. I can't complain. There are more expensive straps available that may fit better or have better buckles, but I can't justify purchasing a $150-200 strap for a watch worth $300.
This band is a nice middle ground between my bracelet and my "Bond" strap. Now I have three watches in one, a full spectrum of looks to match any occasion. Superb.
Excellent fit and quality. Very comfortable on the wrist, and pairs very well with any time piece and occasion. I’ve purchased the 20mm brown version and will definitely purchase other colors. Great job with this one!
