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.

Print File. In print options dialogue box, uncheck any "shrink oversized pages to fit" or "fit to page" boxes. *IMPORTANT!*
After printing, test the accuracy by measuring the "one inch" test strip with a standard ruler.
Cut off the inch ruler from the side and wrap around your wrist to determine your wrist size.
Hold your watch with the lugs framing the blocks below to determine your lug width. There should be no gap or overlap.
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.

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.
Wrap the tool around your wrist, keeping it in place. Make sure the tool feels snug and doesn't slide up or down.
Note the inch number the arrows point to – that's your band size.

If the arrows land between two measurements, choose the smaller of the two numbers closest to the line.
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.

Its bold texture and durable construction make it a perfect match for dive watches, field watches, chronographs, or really any watch that could use a strap with a little extra presence. The waffle weave gives it grip, a distinctive look, and a rugged feel that stands out on the wrist.
The double-pass military-style design adds an extra layer of security while keeping the watch comfortably in place, and the Original BluShark brushed stainless steel buckle provides reliable strength. Two thick keepers, one fixed and one sliding, let you dial in the perfect fit, and all hardware is stitched in place (never glued) for long-lasting durability.
Fit Details: The Orca strap is crafted from 1.5mm rugged waffle weave nylon, delivering incredible strength while remaining soft and comfortable, ready for any adventure yet perfect for everyday wear.
Color: Classic Army Green that leans toward a true green with a hint of yellow, keeping it from drifting too far into brown tones. Great for watches with green accent colors or any outfit!

I think the product is a little over priced but I like the color
Richard W. 4/5 Verified
The strap looks great, however the nylon is a bit rougher than my Bond Orca Strap which is kinda weird. I like it, however my watch tends to live on the Bond for most days.

This was my first strap from the shop and has become my go-to for my Luminox. The strap and is comfortable and the weave has great look to it. Absolutely love it!

Fits comfortably on my 7 inch wrist, and blends in well with my Seiko Alpinist. Great for the outdoors and did well on the water! Recommend 10/10
Benny C. 5/5 Verified
I really like the slightly coarser texture over the other bands. It really suits the watch. Still very comfortable, and not stiff. Highly recommend.
Stephen W. 5/5 Verified
Nice looking, comfortable and durable from what can be assessed after a few days of ownership. Well done!

Size is good, hardware is very nice. Unfortunately the material seemed a little thin.
Bruce B. 3/5 Verified
Store owner replied: Hey Bruce, Sorry to hear the strap isn't going to work for you. The ORCA is one of our thickest straps, and while we'd love to make it even thicker, doing so can create fit issues with many of the watches out there. If a strap is too thick, it may not fit properly between the spring bars and the watch case, and forcing it into place can put strain on the spring bars. That said, this isn't an issue with every watch. We'd be happy to set up a return or exchange for you. Just respond to this message, and we'll be happy to take care of you! Best, BluShark Straps
Really an high quality NATO strap, the color perfectly match with the seconds hand of my seiko sumo!

The BlueShark Orca Black band with Black Physical Vapor Deposition finished hardware is a perfect addition to my collection. I wanted something a bit more rugged than the Original series bands. It has a comfortable thicker (1.5mm) nylon flexible band. Premium hardware with the PVD finish looks awesome. I've been using this band for a few weeks now with no signs of wear or scratches.
