Fifty years after developing its first triple-calendar movements—adopted by several leading watchmakers—Jaeger-LeCoultre launched the Master Control collection in 1992, naming it after its pioneering “1000-Hour Control” certification.

The Q4148480 is a 2022 variation that breaks with the traditional silver dial in favor of a two-tone navy blue dial: a deep blue sunburst center, surrounded by a slightly lighter ring that highlights the minute track. At the heart of this timepiece, the Caliber 866—directly inspired by the “Triple Calendar” watches of the 1940s—displays the day, date, and month, while incorporating the latest technical improvements, including a new barrel and titanium screws for the oscillating weight. Its most elegant complication: once a month, between the 15th and 16th, the date hand jumps the 90 degrees separating the two positions, thus preserving the readability of the moon phase display.

This specific piece, sold in Japan in 2022, comes with its full set and is in like-new condition. It comes from its first owner. For any watch enthusiast seeking an elegant timepiece and a limited edition, the Master Control Calendar is an obvious choice.
