Jaeger LeCoultre Q114258J Master Ultra Thin Perpetual Calendar 18K Rose Gold Blue Dial

This Jaeger-LeCoultre Master Ultra Thin Perpetual Calendar reference Q114258J, introduced in 2024, exemplifies haute horology with its full perpetual calendar and moonphase complication in an exceptionally svelte profile. Housed in a polished 18‑carat pink gold case measuring 39 mm in diameter and a mere 9.2 mm in thickness, this timepiece marries structural elegance with mechanical sophistication. The gradient midnight‑blue sunray‑brushed dial showcases day, date, month, year, and moonphase displays in a harmonious, legible layout—highlighted by refined gold Dauphine hands and elongated applied hour markers. Powered by the in‑house Calibre 868/1 automatic movement, the watch delivers a highly respectable 70‑hour power reserve while maintaining a movement height of just 4.72 mm, reflecting Jaeger‑LeCoultre’s mastery of ultra‑thin complication architecture. A red “security zone” indicator underscores the technical thoughtfulness of the perpetual calendar mechanism, which requires no manual date correction until the year 2100. As a boutique‑exclusive variant, this edition combines both rarity and collector appeal within the refined Master Ultra Thin line. The combination of its slim form, full calendar functionality, in‑house manufacture movement, and tasteful finishing situates the Q114258J as a quietly powerful statement of refined mechanical luxury.
