Vintage Navajo sterling watch band plates that are inlay set with Shiprock mosaic in turquoise and red coral. One has a human figure and the pther a Phoenix bird. Both have crosses. The bird has some turquoise missing from the shoulder area of the wings. 

They measure 1 3/4" long by 1 3/8" wide. Pin tubes measure 5/8" long and the slots are 5/8" and a little bit bent. Together they weigh 24 grams. Tarnished. 

Will work with Apple Watch. Mine is the 38mm. I don't know if the pin tubes will work on the 40mm as I don't have one. 

You can get the expansion part of the watch band on Amazon for around $25.00. The converters for less than $10.00.
