Ninety years ago, Jaeger-LeCoultre created the Reverso, an ingenious solution for polo players who wished to protect the glass of their watches while playing matches. With its swivelling case and distinctive Art Deco lines, it was to become a classic of 20th-century design. The Maison soon began to introduce new aesthetic variations of the Reverso but, for the first 60 years of its life, no mechanical complications were introduced; the Reverso remained a simple, time-only watch.
