I have a medium size wrist and it fits me where its loose and turns around all the time on. It is a very stylish watch the battery still works great on it keeps up with time. It is brand new I bought it maybe a month ago and I just dont wear it. My loss is someone else's gain.
I am honestly not for sure each one that hooks to the watch itself is stretchy I have a medium wrist and there is still plenty of room for the watch to move quite a bit.
