Swiss luxury watch brand Jaeger-LeCoultre rolled out the red carpet to celebrate the 75th anniversary of the Reverso, its signature timepiece collection, Nov. 5 at the Morgan Library and Museum in New York City.

The 400-plus A-list guests at the invitation-only event included watch retailers, watch aficionados, brand executives—including Jerome Lambert, chief executive officer of Manufacture Jaeger-LeCoultre and Ronald Wolfgang, president of Jaeger-LeCoultre North America—and actors Matt Dillon and Joe Pantoliano.

The evening highlight was the U.S. debut and unveiling of the Reverso Triptyque, the first timepiece with three faces. Valued at about $375,000, the watch contains 18 complications, and has six patents pending.

Also on display were a collection of Reversos from different periods of its history, including one of the very first models.

Jaeger-LeCoultre in 1931 created the Reverso—whose case can be rotated 180 degrees (so the face is against the wrist, protecting its dial and crystal)—in response to requests from British officers in India who often smashed their watches while playing polo. Its reversibility was an opportunity for the brand’s jewelers to decorate the caseback. Today, the Reverso is probably Jaeger-LeCoultre’s most well-known and most popular timepiece, and one of the best-known in the watch business.
