Q114258J

The Jaeger-LeCoultre Master Ultra Thin Perpetual Calendar Q114258J debuted in 2024. This model features a pink gold case measuring 39 mm in diameter and 9.2 mm in thickness. The midnight blue sunray-brushed dial displays a full perpetual calendar layout, including subdials for day, date, month, year, and moon phase, arranged with a focus on balance and legibility. Inside ticks the automatic 868/1, a slim in-house movement offering a 70-hour power reserve. It displays hours, minutes, central seconds, perpetual calendar with day, date, month, year, moon phase, and a red zone warning indicator for when adjustments should be avoided. The movement’s architecture remains thin at just 4.72 mm, despite the complexity of its 330 components. The watch is fitted with an interchangeable strap and secured by a pink gold pin buckle. Water resistance is rated at 5 bar.
