Q114842J

The Jaeger-LeCoultre Master Ultra Thin Perpetual Calendar Q114842J debuted in 2024. It features a stainless steel case measuring 39.0 mm in diameter and 9.2 mm in height, housing a silvered sunray-brushed dial with Dauphine hands and elongated applied hour markers. This model displays hours, minutes, central seconds, day, date, month, moon phase at 12 o’clock, year, and a red security zone. All calendar functions are synchronized and adjusted via a single corrector. It is powered by the automatic 868/1, which offers a 70-hour power reserve and remains accurate until the year 2100 without manual adjustment. The movement is visible through a sapphire crystal case back.
