Patek Philippe was the first to create a perpetual calendar wristwatch following a commission in 1925 from a collector named Thomas Emery, and they used a movement that had been created in 1889 for a
link ladies' pendant watch design. Breguet followed in
link 1929 with the No. 2516
link "The Dollfus" and, perhaps unsurprisingly given the brand's endless work in movement development, Jaeger-LeCoultre launched their first perpetual calendar in 1937.
