The Jaeger-LeCoultre Master Ultra Thin Perpetual Calendar Q1142510 debuted in 2024. This version is housed in a pink gold case measuring 39 mm across and 9.2 mm in height. The dial is rendered in a classical eggshell tone with applied markers, dauphine hands, and subdials for the day, date, month, year, and moon phase. Inside ticks the automatic 868/1, a slim in-house movement with a power reserve of 70 hours. It offers hours, minutes, central seconds, perpetual calendar with full four-year indication, moon phase, and a red zone warning to prevent setting errors. The movement measures 4.72 mm in height and consists of 330 components. Water resistance is rated at 5 bar. The watch is paired with an interchangeable leather strap secured by a pink gold pin buckle.
