Arenix sterling, gold, turquoise bracelet watch

A vintage watch I’ve had for more years than I’ll say. Lol. It’s an over the wrist piece. Mother of Pearl face with 12 k gold filled accents. Stamped Japan movement, Hong Kong assembly and STC Sterling 1/20, 12kgf. Needs new battery. 3” long ornamental face, .75” wide. Sterling band stretches, but I wouldn’t go over a 7” wrist. Perfect vintage condition except for battery need.
