Master Ultra-Thin

The Jaeger-LeCoultre Master Ultra Thin Power Reserve, reference Q1378421, is a refined expression of classical Swiss watchmaking. Part of the prestigious Master Control collection, this elegant timepiece reflects the brand’s dedication to precision, balance, and understated sophistication. Combining timeless design with practical complications, this certified pre-owned luxury watch is offered in unworn condition and is accompanied by its original box and papers, forming a complete full set.

The watch features a beautifully proportioned 39 mm stainless steel case with slim, elegant lines that embody the essence of the Master Ultra Thin collection. Its polished surfaces enhance the refined character of the watch while maintaining a discreet presence on the wrist. The silver dial offers a clean and harmonious layout, with applied hour markers and dauphine-style hands that reinforce the classic aesthetic.

A power reserve indicator positioned at approximately 10 o’clock adds both functionality and visual interest, allowing the wearer to monitor the remaining energy stored in the movement. A date display at 2 o’clock and a small seconds subdial at 6 o’clock contribute to the balanced and sophisticated dial architecture.

The watch is paired with a high-quality leather strap that complements the elegant design and ensures comfort for daily wear or formal occasions. Powering the timepiece is the Jaeger-LeCoultre Manufacture Calibre 938, an in-house automatic movement renowned for its reliability and refined engineering. The movement offers a power reserve of approximately 43 hours and reflects the exceptional craftsmanship associated with the Jaeger-LeCoultre manufacture.

Elegant, technically refined, and unmistakably timeless, the Jaeger-LeCoultre Master Ultra Thin Power Reserve represents a distinguished example of a pre-owned luxury watch from one of Switzerland’s most respected watchmakers.
