Jaeger-LeCoultre Master Control Chronometre Perpetual Calendar Q4178180

The Jaeger-LeCoultre Master Control Chronometre Perpetual Calendar watch embodies sophisticated elegance. Crafted in stainless steel, this timepiece features a refined 39 mm case diameter and a sleek 9.2 mm profile, complemented by a perfectly integrated metal bracelet combining brushed and polished finishes. Its captivating dial, with a blue-to-grey gradient and sunray satin finish, stands out for the legibility of its perpetual calendar, laid out across four meticulously arranged subdials. These counters elegantly display the year, month, day of the week and date, along with a moon-phase indication at 6 o’clock—where the moon gleams thanks to hammered gold leaf—enhanced by opaline and *azuré* finishes. Powered by the ultra-thin in-house calibre 868, it offers a 70-hour power reserve and ensures precision certified by Jaeger-LeCoultre’s HPG seal, which complements COSC standards by testing the fully assembled watch under real-life wearing conditions.
