The Jaeger-LeCoultre Reverso Classic Duetto Q2578181 features the iconic Reverso case, allowing for two unique dials that show the same time. The case, crafted from stainless steel, has dimensions of 40mm by 24.4mm and a thickness of 9.5mm, offering a water resistance of up to 30 meters. It is securely attached to a stainless steel bracelet for a sleek look.

On one side, the silvered-grey dial blends an opaline finish with a sunray guilloché central area, complete with applied numerals and slender stick hands, all bordered by a gadroon design set with sparkling diamonds. Flipping the case reveals a striking blue lacquered dial, enhanced by a sunray guilloché texture, where Dauphine hands indicate the time alongside a powdered Arabic numeral at the 12 o'clock mark, with hour markers radiating outward. This side is elegantly encircled by a double row of brilliant-cut diamonds, totaling 60 stones that weigh around 0.85 carats. The driving force behind both dials is the automatic Jaeger-LeCoultre caliber 968, featuring hands that move in opposite directions. This movement operates at a frequency of 4 Hz and boasts a power reserve of 38 hours.
