Size Chart AplWatchBtnStud
If you do not know your wrist size, do the following:
Wrap a soft measuring tape, a string, or strip of paper around your wrist. When using a string/strip of paper, mark the spot where it overlaps with itself, then measure it with a ruler.
Match your measurement to the size guide above to find your recommended size. If you find that your measurement overlaps between multiple sizes, I recommend choosing the larger of the two. 👍
