In summary, the Seiko Astron, the world's first atomic wristwatch, was a groundbreaking timepiece that used atomic radio signals to adjust its time automatically, making it the most accurate watch of its time. It was invented in 1957 by Seiko, with the first commercial model released in 1969. The watch uses a tiny antenna to receive signals from atomic clocks around the world, resulting in accuracy to within one second in every 100,000 years. The creation of the Seiko Astron posed technical challenges, such as miniaturization and power consumption, but its impact on the watchmaking industry was significant, inspiring advancements in other fields as well.

Oddly enough I just got back from hearing a guy talk about this type of stuff, and he said they can now make them around 1cm^3. The one you found must be the older model.
