Own a historic piece of wearable technology with the legendary Seiko UC-3000 Memo Diary. Released in 1984, this "Wrist Information System" stands proudly as the grandfather of the modern smartwatch. Long before Bluetooth or smartphones existed, Seiko engineered this marvel to wirelessly receive calendar appointments, addresses, and memos via magnetic induction directly from a pocket-sized external keyboard. 
Even without the companion keyboard, this watch stands on its own as a striking, retro-futuristic digital statement piece on the wrist. Its unique square black case layout and multi-line dot matrix screen display the day, date, and time with peak 1980s tech style. This example arrives in very good, original condition, ready for any serious digital watch collector. 
Condition Notes (Very Good Original Condition):
  • Aesthetic State: Beautifully preserved vintage condition. The original black matte casing features clean edges and crisp button lettering with minimal face wear.
  • Dial & Crystal: The dot-matrix digital display is clear with great pixel contrast and no bleeding. The protective crystal is in excellent condition, showcasing fantastic visibility. 
  • Strap/Bracelet: Fitted to its original, era-correct black Seiko strap setup which remains perfectly flexible, secure, and ready to wear.
  • Functions: Fully operational. Fitted with a fresh battery replacement, the watch boots up smoothly, buttons respond perfectly, and timekeeping tracks accurately. Note: This listing is for the watch only; the external data-input keyboard is not included.
