Vintage 70s, Embassy by Gruen bangle watch with semiprecious stones

Vintage 70s Embassy by Gruen bangle watch with authentic semiprecious stones: carnelian, moonstone, lapis and goldstone. Hinged and will fit an average woman's wrist. The watch is marked "Japan Movt" Design of the piece is scrolls and loops for a boho feel. Has not been tested, working condition unknown. I believe it just needs a battery.
