This Jaeger-LeCoultre Grande Reverso Ultra Thin Duoface Ref. 278.8.54 is a refined and discontinued interpretation of the iconic Reverso, combining Art Deco elegance with technical sophistication. The stainless steel rectangular case features the signature reversible design, housing two distinct dials: a classic silvered front dial with applied hour markers and dauphine hands, and a contrasting second time zone display on the reverse. Powered by the in-house Jaeger-LeCoultre Caliber 854 manual-winding movement, it ensures precision, reliability, and a slim profile true to the Ultra Thin lineage. The dual-time functionality makes it both practical and elegant. Offered as a full set, this model is highly sought after by collectors for its versatility, timeless proportions, and the enduring legacy of the Reverso design.
