The Master Ultra Thin Perpetual Calendar in white gold represents the finest expression of Jaeger-LeCoultre’s philosophy of elegance through precision. At just 9.2 millimetres thick, it conceals the intricate Calibre 868, a perpetual calendar movement capable of tracking day, date, month, year, and moon phase with seamless automatic adjustment. Each indication is displayed with clarity and restraint, a hallmark of the Master collection’s timeless aesthetic.

The silvered dial achieves perfect visual balance, with crisp typography and dauphine hands framed by a polished white-gold case that radiates quiet sophistication. Every detail reflects the maison’s commitment to technical mastery within the slimmest possible architecture.

This reference Q1303035 gained cultural prominence as the watch worn by Benedict Cumberbatch’s character in Doctor Strange, symbolising intellect, discipline, and transformation. No longer part of Jaeger-LeCoultre’s current catalogue, the white-gold version is highly sought after among collectors for its purity of design and horological significance.

Fresh from a 2025 service, this Master Ultra Thin Perpetual Calendar stands as a refined tribute to the artistry of complication and the enduring spirit of the Vallée de Joux.
