VTG Texas Instrumenets Quartz Watch Women Gold Tone LCD Digital ~Missing Back

Vintage Texas Instruments digital watch. Crystal is in very good condition given its age. There are a few very light scratches that are only visible when tilted just right. All other angles look great. I could not find the specific model, but the bezel is not round, but more square. On the face, it says "Texas Instruments" and "Quartz". The bezel and band are gold tone. The face is a dark brown. It displays hh:mm on one screen, :ss on another, and mm:dd on another. It has two buttons that stick out and one that is recessed. The top button changes the display screen. The bottom button turns on a little light. The center recessed button needs to be pressed with a pin, and is used to program the watch. No back needs a battery
