I just got the braided loop, and I’m not sure about the fit. It turns out my wrist diameter varies slightly during the day. It seems it’s thicker at night. So, at night the loop fits perfectly, but in the morning the watch sits slightly loose. Yesterday during workout it lost track of heart rate for some time, which could be because of too loose fit. I’m not sure if I should get a tighter loop. Then it might be unpleasant at night.
