Watch and Watch Strap Measurements Sizing Guide

• 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, print the BluShark Apple Watch Sizing Guide in step-1 and place your adapter on the measuring blocks located on the bottom of the guide.
