Chapter Four: Master Control and Complicated Reversos
A major player in watchmaking history since the 19th century, Jaeger-LeCoultre celebrated 180 years of watchmaking, starting in its founder’s original workshop, in 2013, and continued to present new horological innovations at the 2014 SIHH. In Chapter One of our serialized history of the brand, we documented the years 1559-1907, and the founding of the Jaeger-LeCoultre watch brand. In Chapter Two, we covered the introduction of iconic Jaeger-LeCoultre timepieces as the Duoplan, the Atmos clock, and the Reverso, covering the years 1912 to 1931. In Chapter Three, we revealed the origins of the Memovox, Jaeger-LeCoultre’s groundbreaking alarm watch. Now Chapter Four presents some of Jaeger-LeCoultre’s more modern timepiece collections from the late-20th to early 21st Century, including the Master Control and the first complicated Reverso watches.
Equipped with functions that were particularly useful in daily life (alarm, automatic winding, time zones…), the postwar creations such as the Memovox, the Futurematic and the Geophysic have bequeathed their philosophy on the current Master Control line. Created in 1992, the latter marked a fundamental new step in the conquest of precision, since in order to deserve the title of “Master,” each finished watch must emerge victorious from a stringent battery of tests performed for a complete 1,000 hours, meaning around six weeks! In setting this new benchmark, the manufacture was able to draw upon over a century of experience. It based these developments in particular on the work relating to the high-frequency calibers introduced in 1970 and on the progress of the automatic-rotor winding systems introduced in 1959.
Embodying the ultimate in horological classicism, the Master Control line was soon enriched with creations equipped with classic watch complications such as the perpetual calendar, the tourbillon regulator, and the minute repeater.

In 1991, the Reverso welcomed its first complications. The chronicles of the Reverso limited series in pink gold, and then in platinum, could begin: tourbillon, minute repeater, perpetual calendar, retrograde chronograph. In 1994, and for the first time ever, the Reverso Duo offered two back-to-back dials displaying two time zones. Its baby sister the Reverso Duetto was created for women; its front evokes the daytime hours while the gem-set back celebrates the hours of night.
In 2006, the Reverso Grande Complication à Triptyque brought together civil time, sidereal time and perpetual time on three faces within the legendary swiveling case. As the first watch in horological history equipped with three dials driven by a single movement, the Reverso Grande Complication à Triptyque interprets three dimensions of time. On the front, civil time is rhythmically measured by an ellipse isometer escapement. The back features an equation of time and the zodiac calendar. Its third dial is integrated into the carrier: an instant perpetual calendar is activated every 24 hours, at exactly midnight. Click here to view the current Jaeger-LeCoultre Reverso collection.
In Chapter Five, next month, we take you further into Jaeger-LeCoultre’s 21st-century milestones, including the first Gyrotourbillon.
