On January 12, 1979, the Swiss watch industry announced the thinnest watch ever made: The Delirium, developed by Ebauches SA for Concord, Eterna, IWC, and Longines, measured just 1.98 mm thick. It wasn’t a big seller, but was a PR exercise to show the world that the Swiss were innovating like the Japanese. And the novel design paved the way for another announcement four years later, the Swatch.
Most enthusiasts could instantly name the watches pictured below, but they’d be wrong: This isn’t a Jaeger-LeCoultre Reverso, its an Eska Sesame! By the 1980s, Jaeger-LeCoultre’s signature model was forgotten and the company was struggling to survive. Yet just a decade later, the Reverso would lead the entire industry back from the brink. This is the story of the fall of Jaeger-LeCoultre and the resurrection of the Reverso.
