The Master Control Chronometre Perpetual Calendar embodies sophisticated elegance. Crafted in stainless steel, this timepiece features a refined 39mm case, measuring a slender 9.2mm thick, complemented by a seamlessly integrated metal bracelet with brushed and polished finishes. Its captivating blue-gray gradient sunray-brushed dial is distinguished by a legible perpetual calendar display, presented across four meticulously arranged sub-dials. These counters elegantly indicate the year, month, day, and date, alongside a moon phase indication at 6 o'clock, where the moon glows with hammered gold leaf, all enhanced by opaline and azuré finishes. Powered by the ultra-thin Manufacture Caliber 868, it boasts a 70-hour power reserve and ensures a precision certified by the Jaeger-LeCoultre HPG Seal which completes COSC standards by testing the entire cased-up watch in real-life wear conditions.
