Which Swiss watchmaker developed the reversible Reverso watch in 1931?

Jaeger-LeCoultre developed the reversible Reverso watch in 1931.

The Reverso was created for polo players in British India, who needed to protect the fragile crystal and dial during matches. Its case could slide and turn within a frame, placing the dial face-down and exposing a metal caseback to impacts.

The original design was patented in 1931. Its rectangular Art Deco form and ingenious reversible case made it both a practical sports watch and a distinctive piece of design history. Owners could also personalize the blank reverse side with engraving.

The Reverso is associated with Jaeger-LeCoultre, although the company’s name and corporate history changed over time. It should not be confused with Cartier’s Tank, another famous rectangular watch that was introduced earlier, in 1917.
