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.
• Apple Watch Instructions
1) Open Our Apple Watch 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) 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.

American FKM Rubber: This formula is known for its superior resistance to heat, chemicals, and weathering compared to other rubber materials. It's often used in applications that require durability, such as in the aerospace industry.
What sets American FKM rubber apart from other formulas, like standard FKM or silicone rubber, is its specific chemical makeup, which is formulated to perform better in extreme environments. American FKM tends to offer:
- Higher Heat Resistance: Can withstand temperatures as high as 300°F (150°C), which is ideal for use in extreme conditions.
- Chemical Resistance: Resists oils, fuels, solvents, and acids better than many other elastomers.
- Durability: It tends to have a longer lifespan in harsh conditions, making it ideal for long-lasting products, like watch straps exposed to sweat and moisture.
- Elasticity: Despite its strength, it maintains flexibility and a comfortable feel, which is great for wearable items.
