Master Ultra Thin Perpetual Calendar

Jaeger-LeCoultre has revamped its Master Ultra Thin Perpetual Calendar collection for 2024. This collection aims to exude elegance and display mechanical prowess, drawing on the brand’s expertise in crafting thin movements. The new timepieces feature a modernized case and dial design and a significantly improved power reserve.

The Perpetual Calendar complication is exceptionally challenging due to the irregularities of our calendar compared to celestial cycles. Jaeger-LeCoultre’s Calibre 868, powering this watch, is a testament to their mastery. It includes technical innovations such as a new escapement and pallets, offering a robust 70-hour power reserve.

Despite the enhancements, the case retains its elegant 39mm diameter and 9.2mm thickness. The design tweaks include slimmer lugs for better comfort and a refined dial layout for improved legibility. Subtle changes like elongated hour markers and different finishes on the hands contribute to a more cohesive and elegant design.

Four versions, including models with gradient midnight blue, eggshell, and silver dials, are available in pink gold or steel cases. The Master Ultra Thin Perpetual Calendar is presented on an alligator strap with a pin buckle.
