That has to be a very small wrist considering the claimed size. I know I have a few i wonder about and my wrist isn't that small. But truth be told, how tight do you measure?
I measure so the tape touches all the way around.
I also am a firm believer in how your wrist is and I don't see much talk about the actually physiology of the wrist.
Is your wrist flat or round? Mines round but i see plenty of flat wrists which IMHO allows for a bigger watch on what measures as a smaller wrist because being flat there's a bigger top area in width.
Did that make any sense?
