2001 Jaeger-LeCoultre Master Control Calendar
A Master Control with a stunning silver dial, a triple calendar moonphase, and the JLC 891/448 automatic movement.
Overview
In 1992, Jaeger-LeCoultre debuted the vintage-inspired Master Control collection as a tribute to the brand’s unmatched watchmaking heritage. No longer just “the watchmaker’s watchmaker”, the Master Control collection ushered in a new era where the company was once again dedicated to exceptional watchmaking and production under its own name. Throughout the years the collection has seen a number of horology’s most famous complications including the moonphase indicator, triple calendar, chronograph, world timer, 8 days power reserve, and perpetual calendar. What’s more, each Master Control watch has undergone the brand’s strict “1,000 Hour Control” testing period, during which the movement is cased, rigorously examined beyond COSC certification protocols, and hand-adjusted for accuracy in six positions.
The watch here combines the romanticism of the moonphase indicator with the practicality of the triple calendar to create a single stunning timepiece. Boasting dauphine hands, dart-style indices, and Arabic numerals at 12, 3, and 9 o’clock, the style of this watch is reserved and classically executed. Yet the radial date and two central apertures contain splashes of red that liven up the dial, giving it just enough flair to capture one’s attention throughout the day. The back of the watch commands another look as well, showing off the impressively finished 891/448 automatic caliber with a 22C gold-tipped rotor that proudly displays the Master Control 1,000 Hours certification. With its sleek look and universally wearable 37mm case, this Master Calendar is a perfect encapsulation of Jaeger-LeCoultre’s beloved watchmaking prowess.
