Seiko RC-1000 Wrist Terminal (Full Kit)

The Seiko RC-1000, released circa 1984, is a pioneering example of wearable technology, often cited as one of the world's first 'smart' watches. It features a high-impact black plastic and stainless steel construction with a distinctive rectangular digital face. This specific example is presented in its original retail packaging, including the 'Data Transmission Software' box, user manuals, and the proprietary interface cable required to connect the watch to early personal computers like the Apple II, Commodore 64, or IBM PC. The watch head itself remains seated in its original internal plastic tray, appearing to be in unused (New Old Stock) condition. Notable design elements include the side-mounted interface port for data transfer. The external cardboard packaging shows minor shelf wear, light edge fraying, and some characteristic warping (box 1 and 2), with the white interior of the top flap displaying mild yellowing due to age-related oxidation. Despite these cosmetic storage issues, the item is exceptionally rare due to the inclusion of all original leaflets and the intact software media box, representing a complete set for computer history enthusiasts and horological collectors.
