This is so interesting—I tried on a love bracelet in size 16 the other day and the inner screws were getting caught over my wristbones. I tried this size a year ago with zero issues, and I don’t think it’s a weight/swelling problem because it was just over the bony part of my wrist. Such a bummer because I had finally wanted to pull the trigger. I guess I might have to try an older/secondhand model? Or hope for half-sizes to be released someday, because the size up (17) was much too loose.Could be the screw system. It's changed about three times in the last 15 years. The different mechanisms on at least one of them have different thicknesses in the portion that touches the wrist owing to the depth of the closure system. At least, that's what I had been told by a SA some time ago.
