Launched in 2026, the Jaeger-LeCoultre Reverso Classic Monoface Origin Q3878160 features a five-row bracelet crafted from stainless steel, known for its grain de riz texture. Its design takes inspiration from the 1931 Reverso Lady, with a case size of 32.5 mm by 16.3 mm and a thickness of just 6.95 mm. The watch boasts a unique 50-part swiveling case, which includes a plain reverse side perfect for personalization through engraving or lacquer finishes. The distinctive gadroons of the case are adorned with thirty brilliant-cut diamonds, totaling 0.13 carats, enhancing its elegance. This piece is rated for water resistance up to 30 meters.

The silvered-gray dial showcases a captivating sunray guilloché pattern in the center, complemented by a vertically brushed outer section. For timekeeping, twelve black Arabic numerals are positioned along a chemin de fer minute track, and the hours and minutes are displayed via blued stick hands. The watch is driven by the Jaeger-LeCoultre caliber 657, a quartz movement with a thickness of 2.15 mm, allowing for a refined, slender silhouette. The reference Q3878160 is beautifully finished with the same five-row stainless steel grain de riz bracelet, tying the design together.
