Introduced in 2026, the Jaeger-LeCoultre Reverso Classic Small Duetto Q2668123 features a unique design with a reversible stainless steel case, complemented by a five-row bracelet of the same material. The dimensions of the case are 34.2 mm in length, 21 mm in width, and a thickness of 8.7 mm, ensuring a compact yet elegant profile. Surrounding both dials are gadroons set with 60 brilliant-cut diamonds, amounting to a total of 0.56 carats, while the watch boasts a water resistance of up to 30 meters.

This timepiece showcases two distinct faces, each marked by contrasting colors and finishes. The recto dial presents a silvered-grey hue, featuring a sunray guilloché center and satin-brushed outer sections, adorned with twelve silvered Arabic numerals and an applied JL emblem, along with blued stick hands. Conversely, the blue verso dial combines a sunray-brushed inner part with an outer layer of sunray guilloché. Time is indicated by silvered Dauphine hands. The watch is powered by Jaeger-LeCoultre's hand-wound caliber 844, which powers both dials to display the same time, albeit with the hands moving in opposite directions. Operating at a frequency of 21,600 vibrations per hour, the movement offers a power reserve of 50 hours. Reference Q2668123 comes with a stainless steel five-row bracelet featuring a double-folding clasp, along with an interchangeable blue alligator leather strap.
