This is a Vintage Original Texas Instruments LED Wristwatch Model TI-503-4 made in 1976. It was one of the first models that TI produced. I received it as a graduation gift from my parents. I wore it occasionally for about six months and then put it in storage until I took it out today to take my photos. As you can see from the photos it is cosmetically in Outstanding Condition. I have no idea if it would still work with a battery replacement. 

   Rest assured that this watch will be packaged and shipped safely and securely. Thanks for viewing my listing!
