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.
• Traditional Watch Instructions:
1) Open Our Sizing Guide Here. Download Here
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.

2) Print File. In print options dialogue box, uncheck any “shrink oversized pages to fit” or “fit to page” boxes. *IMPORTANT!*
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.

AlphaShark — Tracer (Gray, Black, & Red) Double-Pass Seatbelt Nylon Watch Strap
Built to Last
The AlphaShark is built from ultra-durable, heavy duty seatbelt weave nylon — a 1.4mm thick, high-sheen weave cleanly stitched around the buckles for a refined finish that doesn't sacrifice strength.
Why Double-Pass Is More Secure
What makes a double-pass strap better than a single-pass strap is the extra layer of material under the watch case. The AlphaShark's double-pass construction uses a second, shorter piece of nylon that runs beneath the case in addition to the main strap - so there are two layers of webbing between the spring bars and your wrist instead of one. A single-pass strap uses just one continuous strip of material running underneath the case.
Both styles are pass-through designs, meaning the strap itself wraps under the watch case rather than attaching as two separate pieces. That's what makes pass-through straps - single-pass or double-pass - more secure than a two-piece strap: if a spring bar fails, the strap stays in place and keeps the watch on your wrist, since it isn't relying on the spring bars to hold two separate halves together.
Bond Scarlet
Tracer is a gray with black and red stripes pattern, making it a tactical-inspired colorway combining neutral gray with black and red accent stripes. Popular with tool watch, dive watch, and field watch wearers who want a rugged, layered look
What Makes AlphaShark Different
What sets the AlphaShark apart from standard seatbelt nylon straps is the nylon itself. The 1.4mm weave is noticeably thicker and more durable than standard nylon straps, while still finishing with a higher sheen and softer hand-feel than typical nylon webbing. It breaks in over time, becoming more supple with wear without losing structure.
Each strap is finished with a stainless steel buckle and one fixed, one adjustable keeper to tuck the strap tail securely in place.
