Jaeger LeCoultre Reverso Large 'Duo-Face'

Although a significant portion of wristwatches in the 20th Century development are based on rectangular proportions, not many have left behind an iconic legacy as the Cartier Tank and Jaeger LeCoultre Reverso.

Both seemingly simplistic and petite, the two pieces embed a much more in-depth story with Edmund Jaeger being the mechanical ‘man’ behind Louis Cartier’s execution of his first series. The duo-plan movement has not only influenced how movements and complications could be restructured and repositioned but pioneered possibilities ie. Minute Repeater, Tourbillon, Serpentine Day-Night and Perpetual Calenders for numerous settings from one singular case shape. The glory lies in the motion and operation of the case mechanism which we think fundamentally has transformed how rectangular wristwatches are portrayed and remains an exemplar to date.
