2021 Jaeger-LeCoultre Reverso Classic Duoface – Dual Time Zone Reversible Case

From Jaeger-LeCoultre’s iconic Reverso collection, the Classic Duoface represents nearly a century of Art Deco design evolution paired with genuine dual-time complication. This isn’t just a reversible case—it’s two independent time zones, each with its own dial, powered simultaneously by a single movement.

The front dial features JLC’s signature guilloché pattern in silver—hand-applied horizontal lines creating subtle light play. Flip the case 180 degrees, and the reverse reveals a completely separate blue sunburst dial displaying a second time zone. The manual-wind Calibre 854A/2 achieves what many dual-time watches cannot: maintaining slim proportions (9.73mm thick) while powering two separate displays with independent hour hands. This allows you to track home and travel time without mental gymnastics or GMT hand confusion.

The reversible case design originated in 1931 for polo players needing to protect crystals during matches. Today, the Duoface serves a more practical purpose: quickly checking two time zones by flipping the case rather than reading a GMT hand. At 47mm x 28.3mm, the rectangular case appears substantial but wears elegantly thanks to Art Deco proportions and slim profile. This 2021 example shows minimal wear consistent with three years of careful ownership.
