On the right hand side of the screen, you can see three options.
Option 1: Measure your wrist with a ruler/scale - is pretty simple to use. Measure your wrist and then slide the red dot on the gray ruler to indicate the right reading. Do pay attention to the right way of measuring your wrist. The pictorial indication is given above the gray line with the red dot.
The image of the watch will pop up when you slide the red dot. For instance, if you have chosen 6 cm for a guy’s hand and you wear your watch on your left hand and you have also adjusted the red dot to read 6 cm.
Option 2: Print a Ruler/Scale and measure - will give you an image of a ruler that you can print and then use to measure your wrist. You can then adjust the red dot according to your measurement and specs.
Option 3: Measure with your WebCam (You will need a CD) – requires you to simply hold a CD in the specified manner and allow the website to access your webcam. When you click on this choice, you will get a screen with all the necessary guidelines.
