In reply to I don't know if you see by Wynot
The Navajo and Zuni are two first nation (native) tribes in the American southwest (Arizona and New Mexico) that are the originators for much of the turquoise, coral and silver jewelry. Necklaces, pendants, rings and watch bands are all common. The design themes are often cultural representations from their heritage. These items are quite popular, my father owned several rings and bolos but I don't recall him ever having one of the watch bands. I can't recall ever seeing one of these bands in gold but it is possible it was Navajo or Zuni made.
The other American phenomenon around watch bands I often see on eBay are the watch bands covered with unprocessed gold nuggets. During the oil boom in the 1960's and 1970's there was in influx of highly paid worked to the Alaska oil fields. These workers often came back with watch bands heavily encrusted with gold nuggets. I've also seen them with animal figures cast from solid gold.
