What's My size?
TO FIND YOUR CASE SIZE, CHECK THE ENGRAVING ON THE BACK OF YOUR IWATCH
What's My Wrist size?
Use a string or paper. With your palm open and facing up, wrap the string or strip of paper around your wrist, just above your wrist bone. Mark where the ends meet with a pen or a marker. Next, lay the string or piece of paper flat and measure it to where you've made the mark to find your wrist size and note it down.
