Released in 1990 as part of the Swatch Originals Gent line, the GB720 Broadcast is one of the more striking pieces from that period — a matte black dial with gold accents that reads as considered rather than busy, and which has held the attention of collectors for the thirty-odd years since. At 34mm in resin, it sits flush against the wrist in a way most watches rated for daily wear do not, the sub-9mm case barely registering under a cuff. The day-date window at three o'clock is a practical touch that keeps the dial from feeling purely decorative. What distinguishes surviving examples now is condition. This one comes unissued, in its original box with paperwork — the sort of find that turns up rarely and matters to anyone serious about Swatch's early Originals run.

Learn more about Swatch
Swatch was the Swiss industry's answer to its own near-death. By the early 1980s Japanese quartz had reduced Swiss watch exports catastrophically and employment had collapsed. Nicolas Hayek, brought in as a consultant to advise on liquidating the ASUAG and SSIH conglomerates, recommended the opposite: merge them and attack the low end.
The engineering that made it possible was radical. Ernst Thomke, Elmar Mock, and Jacques Müller designed a watch with fifty-one components instead of the usual ninety-odd, with the movement assembled directly into the injection-moulded case so the watch could not be opened or repaired. It could be made in Switzerland, by robots, for less than the Asian competition.
The first Swatches went on sale in 1983. They were cheap, plastic, colourful, and — critically — sold as fashion rather than as timekeeping. Buyers owned several. Artists including Keith Haring, Kiki Picasso, and later Vivienne Westwood designed editions, and some early models now trade for thousands.
Swatch sold over a hundred million watches within its first decade and financed the rescue of the entire Swiss industry. The Swatch Group that resulted owns Breguet, Blancpain, Omega, Longines, Tissot, Hamilton, and Glashütte Original, and remains the largest watch company in the world.
The MoonSwatch collaboration with Omega in 2022 caused queues around the world.
