[ SERIES 500 ] TEXAS INSTRUMENTS USA 1974



A Huge Array of Colors and Shapes

These Texas Instruments LED watches feature distinctive plastic cases. The models use the same module but feature a wide variety of case designs and color variations. To provide them at as low a price as possible, the company used plastic and other cost-saving materials for the exterior cases. To eliminate processing such as using screws to hold the modules, the company used plastic welding to affix the metal parts.
