Jaeger-LeCoultre’s Reverso watch turned 80 this year. To celebrate this milestone, a party was held at Ecole Nationale des Beaux-Arts in Paris. This watch is an icon in the watch industry like the Calatrava is to Patek Philippe and the Submariner is to Rolex. On display at the event were 80 different Reverso watches from 1931 to the current Gyro-Tourbillons. These watches are timeless.
