Seiko UC-2000 (1984) Wrist Information System
UC-2000 aka Wrist Information System Cal. UW01-0010
The UC-2000 is a classic 'nerd watch' with a gray bezel and stainless steel band, part of the UC-2000 Series Wrist Information System. Like the Data-2000, it pairs with a pocket-sized beige UC-2100 keyboard. Two variants exist: the UK01-0020 (61 keys) and UK01-0010 (62 keys, with a Kanji toggle for Japan).
The UW01 module stores 2,000 characters and supports time, date, stopwatch, alarm, and hourly chime functions. While not waterproof, it is Y2K-compliant.
One of the few watches to display seconds, date, and day simultaneously, it features a large dot matrix display that spells out the full day name.
