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.

Hello. The strap is advertised as leather And rubber however it looks like there is simply a leather looking stamp impression made in rubber. To my eye there isn’t any leather. I remain disappointed.

Hey Christopher, that’s definitely not supposed to be happening. I ran a few tests on the straps we have in stock and wasn’t able to replicate the issue, so unfortunately it looks like the strap you received has a major defect. I’ve reached out to you via email and would be more than happy to send a replacement or another strap if you’d prefer.
Very nice and elegant !!! I highly recommend it. !!!
Not what I was hoping for. More like rubber than leather. Strap keepers almost too small, very hard to insert end of strap into keeper. Would not but again.
I recently purchased the Leather & Rubber Red Watch Strap from BluShark, and I couldn’t be more impressed! The combination of a soft leather top with an FKM rubber body makes it both luxurious and durable—perfect for daily wear and outdoor activities.
The flexibility and comfort are outstanding; it feels great on my wrist from the first wear. The quick-release pins make swapping straps effortless, and the double floating rubber keepers ensure everything stays in place. The two-tone design with the black rubber base and red leather top adds a sleek, modern look to my watch.
The Black PVD buckle feels premium, and I love that there’s now a brushed buckle option available. The taper from 3.4mm to 2.8mm makes for a great fit without feeling bulky.
Overall, this strap is an absolute winner—great craftsmanship, stylish, and super comfortable! If you're looking for a high-quality, stylish, and durable watch strap, this is a must-have. Highly recommend!

Wow! Mark, thank you so much for taking the time to leave such a detailed review of this strap. We all really appreciate it and are so glad to hear you love it!
Pliable sweat and water resistant and good looking
Really appreciated the customer service provided and sending me a replacement strap however this one did the same thing after 1 week of normal wear. The finish is sadly peeling away.

Hey Troy, thanks for sharing this with us. That's not something we typically see with these straps. I'd be happy to have a replacement sent your way! I'll send over an email shortly to get this started for you
Great strap for my Casio field watch. Casual elegance! Easy on and off (I have a black one too)!
I've had my order for a week now and I absolutely love the fit, feel and comfort of these blu shark straps. The quality of these straps is instantly noticeable, they feel solid not like the flimsy cheap amazon straps ive purchased in the past, they also have quick release bars which make switching in and out of straps a breeze. I bought straps for all my moon swatches as (pictured) and they look brilliant, Everyone has been complimenting the strap/watch combinations. Once you place the order The company keeps you informed every step of the way which highlights the attention to detail blushark has. Overall I've had a great experience and will be buying more soon.

Thank you so much for your review, Letty!
I love this strap more than I thought I would! It looks great and seems to be good quality so far (a few weeks in). I have a tiny wrist and this is the perfect size.
