My wrist measured to be about 200. I went ahead and ordered the watch and then went for the fitting. The band was a little snug going over the hand, but it rides very nicely on my wrist. The strength of the magnet is very good and I find myself maybe adjusting it maybe twice during the day.
I find it very comfortable and after having it for nearly 3 weeks, don't really notice it on my arm.
Still waiting for my BSB, but with the other reports of peeling, hopefully by the time they ship mine, it will be from a new & improved batch. Definitely glad I went with the Milanese first
