What do the metal stud on the wriste band do?
Hi
What does the metal stud on the wristband do?
I would like to get my mother an Apple watch to help her monitor her blood pressure and overall health. She is overweight and wants to lose weight. So she currently working out to better her health. Because of her weight issue, she has large wrists, and the standard wristband is too small to fit around her wrist. So I figured I could get a larger after-market wristband, but I noticed they do not have the metal stud on them.
So can anyone provide a clear explanation of what the metal stud does and if it's needed to monitoring health metrics like blood pressure.
Thanks for your help.
