Welcome to PCW'85 – Seiko RC-1000 computer watch

Updated 31 January 2026

This is the third and final installment of Database covering the PC World conference in 1985. We are wrist-deep in technology, with a geek’s eye on programming, productivity, and the quiet optimism of the era. This episode brings it all together. Hints of vintage computer collectables are everywhere. There is Pascal programming, VisiCalc, and the quietly astonishing Seiko RC-1000. What once looked like novelty now reads as early ambition.

Database TV Show (June 1985)

I’ve watched this episode a few times over the years, and what strikes me now is how restrained the Seiko RC-1000 looks on screen. Calculator watches were everywhere at the time — clever, functional, and undeniably a novelty. How often does anyone really need to multiply 99 by 9 on their wrist? Visually, the Seiko is simpler, almost understated, and that simplicity hides the fact that it is far more capable.

Watching it again, I couldn’t help thinking that modern smartwatches suffer the same identity problem. A computer on your wrist is a great idea — but what are you actually supposed to do with it? Even today, the real breakthrough hasn’t been productivity so much as health monitoring and passive support. The questions haven’t changed much in forty years.

Dr Mike Thorne spends a good amount of time hovering around the Oxford Computer Systems stand. They’ve produced a full implementation of the structured language Pascal for the Commodore 64 and the BBC Micro. Some BBC Micro configurations even require an additional processor. This is Oxford Pascal, and it comes with extensive extensions to exploit the C64’s graphics and sound capabilities.

Pascal mattered. It was the modern language of the time, taught in universities and associated with “real” computing. Yes, we all know that the best commercial software — especially games — was written in assembly language to squeeze every last cycle and byte from the hardware. But many people bought a Commodore 64 because they wanted to join the computing future. There was no point owning a computer that couldn’t compile the language you were learning.

Mike demonstrates the Pascal compiler, and I’m mildly shocked by how much airtime this gets. Still, it’s hard not to enjoy it. The source listing looks BASIC-like, complete with four-digit line numbers. That alone makes Pascal feel oddly constrained. Compilation takes around ten to eleven seconds — impressive, or not? I find this part unintentionally funny. BASIC interpreters were slow, but even today a meaningful compile can take just as long. Back then, top-tier development often happened on larger systems before code was pushed down to the microcomputer. Memory and storage were precious.

I also admire the physical setup: the Commodore 64 breadbin, the television monitor, and the floppy drive perched neatly on top. There’s probably some interesting magnetic interaction going on there, not to mention the risk of the drive being knocked off in a busy exhibition hall. It feels very real, very human.

The episode also introduces the Visicode competition winners. The secret code was Stonehenge, and it clearly wasn’t trivial. One line from the presenter lands awkwardly today — “it’s really nice to see a female in the pack” — followed by a flat “my husband made me do it”. It’s a small, telling moment that dates the broadcast without needing commentary.

Then Tony gets the last word, and that word is Japan Inc. Specifically, the Seiko RC-1000. It’s presented as the future of technology. Buyers wanted one, even if the interface was clunky and the practical use cases were limited. But if you could find your own niche, you were already ahead of the Joneses next door.

I’ve written elsewhere about using a modern smartwatch as a workstation peripheral, and the lineage is clear. The aspiration hasn’t changed, only the tools. The RC-1000 is a quartz multi-function computer terminal you wear on your wrist. It even has an alarm — vital, apparently, for reminding you when to watch Database — and yes, it also tells the time.

Data transfer happens via an RS-232 interface to the wrist terminal. And what do you get for all that effort? A glamorous executive wrist toy, aimed at travelling salespeople, if the show is to be believed. In hindsight, it’s easy to smile — but it’s also easy to see the future trying to arrive early.

Watching this now fills me with a kind of heartbreak nostalgia. These huge, expensive expos — PCW, Commodore World — captured a shared sense of technological momentum. Crowds gathered to see the future together. Today, you often need to fly halfway across the world to get anything close, and even then the feeling is different.

And now, let’s use the RC-1000 terminal to run the credits…
