This is a metal mesh one-piece watch band for the 42mm Apple iWatch. It attaches to the iWatch as well as the original bands by sliding it into the ends of the watch. The silver band then is secure and adjusts to the size of your wrist by just looping it over and letting the magnet adhere to the band.
The wrist closure is stainless steel and may scratch with wear and tear, as do all watches and metals. The strong magnetic clasp ensures that the watch will stay on while playing sports or other physical activity.
