(1931) JAEGER-LECOULTRE REVERSO
The legend goes something like this: one day in 1931 at a polo club in British colonial India, Swiss businessman César de Trey attended a match. After the game, he noted that one of the players had broken the mineral crystal on his watch, and de Trey’s next challenge was born: to create a model robust enough to withstand the trials and tribulations of a polo match. De Trey took on the development of the case he envisioned together with engineer Alfred Chauvot, and entrusted the movement making to Jacques-David LeCoultre. A patent was filed for a watch “capable of swivelling by sliding in its base” on March 4, 1931. The name Reverso means “I turn around” in Latin.
