Description

Rare vintage Seiko RC-4000 PC Datagraph from 1985.

The RC-4000 was one of Seiko's early computer watches and was designed as a wearable databank. It features a full dot-matrix LCD display and can store personal information, memos and schedules directly in the watch.

The watch uses the Seiko S521 quartz module and was designed to communicate with personal computers through its data-transfer system. The RC-4000 could store up to 80 pieces of information and was compatible with computers of its era, including Apple II and IBM-compatible systems.

This particular example has the S521-4000 case reference and serial 582571, dating it to August 1985.

The watch has the original integrated stainless-steel bracelet and distinctive black/gold styling. Please study all photos carefully for the overall cosmetic condition.
