Jaeger-LeCoultre Master Calendar Q4142520

The Jaeger-LeCoultre Master Calendar Q4142520 is an elegant mechanical timepiece from the prestigious Master Control collection, combining traditional Swiss watchmaking with a sophisticated full calendar display. Presented in a refined rose gold case with a silver dial and brown leather bracelet, this model offers a classic dress-watch aesthetic with useful calendar complications.

The Jaeger-LeCoultre Master Calendar Q4142520 measures 40 mm in diameter and features a slim 10.95 mm case profile. Its rose gold construction gives the watch a warm, luxurious appearance, while the silver dial creates a balanced contrast that keeps the overall design refined and highly legible.

At the heart of the Jaeger-LeCoultre Master Calendar Q4142520 is the automatic Calibre 866. This mechanical movement provides an impressive 70-hour power reserve and contains 34 jewels. Its automatic winding system allows the watch to be powered naturally through wrist movement, making it suitable for regular wear while preserving the traditional character of mechanical watchmaking.

The defining feature of this Jaeger-LeCoultre Master Calendar is its comprehensive calendar display. The watch indicates the date, weekday, month, and moon phase, bringing several practical and astronomical indications together in a single elegant timepiece. These complications are a hallmark of traditional calendar watchmaking and give the Master Calendar considerably more visual and mechanical interest than a conventional time-and-date watch.

The silver dial works particularly well with the rose gold case. Its understated appearance allows the calendar indications to remain the focus without making the watch feel overly complicated. The brown leather bracelet further reinforces its classic character and makes the watch particularly well suited to formal and business attire.

With a 40 mm case diameter, the Jaeger-LeCoultre Master Calendar Q4142520 offers contemporary proportions while retaining the restrained character associated with traditional dress watches. Sapphire crystal provides a durable transparent surface over the dial, while the 5 ATM water-resistance rating offers protection suitable for everyday conditions, although the watch is best treated as a refined mechanical timepiece rather than a sports watch.

This example is listed in Used (Very Good) condition and shows only minor signs of wear, described as small and intangible scratches. It is offered as a full set with the original Jaeger-LeCoultre box and original papers, adding to its appeal for collectors and enthusiasts who value complete ownership documentation.

The Jaeger-LeCoultre Master Calendar Q4142520 is an excellent choice for anyone looking for a sophisticated luxury watch with a rose gold case, automatic movement, extended power reserve, and traditional calendar complications. Its combination of moon phase, date, weekday, and month indications gives the watch genuine horological character while maintaining an elegant and wearable design.
