Jaeger-LeCoultre Master Eight Days Q1618420

The Jaeger-LeCoultre Master Eight Days Q1618420 is a sophisticated mechanical timepiece combining traditional manual-winding watchmaking with an impressive eight-day power reserve and a perpetual calendar. Part of the Master Control family, this reference presents its complications in a refined 40mm steel case with a silver dial and black leather bracelet.

At the heart of the Jaeger-LeCoultre Master Eight Days Q1618420 is the manually wound Jaeger-LeCoultre Calibre 876-440B. The movement provides an exceptional 192-hour power reserve, equivalent to eight full days of operation when fully wound. This extended autonomy is a defining characteristic of the Master Eight Days concept and makes the watch particularly appealing to collectors who appreciate technically sophisticated mechanical movements.

The watch combines its long power reserve with two highly desirable calendar-related complications: a perpetual calendar and moon-phase display. A perpetual calendar accounts for the varying lengths of months and the leap-year cycle, making it one of the more sophisticated complications in traditional mechanical watchmaking. The moon-phase indication adds another classic horological element to the overall display.

The 40mm steel case gives the Jaeger-LeCoultre Master Eight Days Q1618420 a versatile and contemporary presence on the wrist. Its steel construction is paired with a silver dial and sapphire crystal, creating an understated aesthetic that allows the watch’s mechanical character and complications to remain the focus.

A black leather bracelet completes the configuration. The leather strap is paired with a steel fold clasp, giving the watch a traditional dress-watch character while maintaining the practical versatility of the 40mm case.

This example is offered in Used (Very Good) condition. The supplied listing states that the watch shows minor signs of wear, such as small, intangible scratches. It is supplied as a full set with the original box and original papers, adding value for collectors who place importance on complete documentation and presentation.

The Jaeger-LeCoultre Master Eight Days Q1618420 is particularly suited to enthusiasts who appreciate complicated mechanical watches without an excessively large case. Its combination of an eight-day power reserve, perpetual calendar, moon phase, manual-winding movement and 40mm steel case gives it a distinctive position within Jaeger-LeCoultre’s sophisticated Master collection.

With its 192-hour power reserve, Calibre 876-440B movement, perpetual calendar and moon-phase display, the Q1618420 represents the technical and traditional side of Jaeger-LeCoultre watchmaking. The full-set configuration further makes this an attractive proposition for collectors seeking a well-preserved example with its original accessories and documentation.
