Unsigned Navajo sterling silver watchband plates. They channel are inlay set with channels of copper. Dark blue natural AMerican turquoise and white bovine bone. They measure 1 3/8" long including the pin tubes and rings and they are 3/4" wide at the widest point. Pin tubes are 3/8" long. Total weight is 12.5 grams. They will work for an Apple watch, this is the small one in the photos. However the pin tube is too short so you will need to add beads to the pin on each side of the tube to keep is straight or have a jeweler extend the tubes.
