Offered here is a rare and increasingly collectible Matsuscom onHand Wearable PC (Model MC120-UG) — an early wrist-mounted personal computer from the late 1990s, long before modern smartwatches existed.

This unit remains factory sealed and unopened, making it a true time-capsule example of early wearable computing technology. Ideal for collectors of vintage electronics, wearable tech history, or museum/display use.

Why This Item Is Special

The Matsuscom onHand represents one of the early attempts at putting a personal computer on the wrist — a precursor to today’s smartwatch ecosystem. Linked to a Windows PC, it allowed users to carry schedules, contacts, notes, and more directly on their wrist.

Sealed examples are rarely found and highly desirable to collectors.
