It has been 25 years since the Master Control collection was first unveiled In 1992.

Now on the collection's 25th anniversary, the Manufacture is presenting a new expression of the line's three emblematic functions, drawing on Jaeger-LeCoultre's rich legacy of round watches to inspire the Master Control Date, the Master Chronograph, and the Master Geographic.

The classicism that characterises the collection is augmented by the vintage charm of these pieces, driven by automatic movements and enhanced with touches of blue. This navy shade echoes across the dial like a leitmotif, in the skeletonised baton hands and the blued stainless steel central seconds, as well as in the complications and the minute circle.

On the face of each watch, a circular satin-brushed finish in the outer section sets off the opaline finish at the heart of the dial. This makes light bounce off it at different angles, ensuring the indications are easier to read. The contrast is further heightened by black hour-markers at the centre of the watch.

Its clean, rounded lines reflect the essence of the Master Control collection, with its emblematic numerals 6, 9, and 12 retained, and the 3 making way for a date indication. This simple function remains a "must" in watchmaking. It has an automatic movement housed in a 39 mm case. The case has a height of 8.5 mm. Through the  sapphire crystal case-back you can see the Jaeger-LeCoultre Calibre 899/1 with its 22-carat gold oscillating weight. The movement runs at 28,800 vibrations per hour, offering a 38-hour power reserve.

Master Chronograph Reference Q1538530

This chronograph watch follows the Master Control collection's distinctive aesthetic lines, featuring a contemporary design inspired by vintage styling. The two push-pieces housed on the case-band make the chronograph easy to use, with its two counters indicating hours and minutes set out harmoniously on the dial. Their invigorating blue colour is echoed in the blued stainless steel hands and the tachometer that runs discreetly around the outer perimeter. It is useful for measuring the speed of travel from one point to another with ease. There is a sporty feel to this automatic watch, and its 40-mm diameter case adds a real sense of distinction to the wrist. The water resistance is 5 bar.

The Master Chronograph is driven by an utomatic mechanical movement, Jaeger-LeCoultre Calibre 751G. It runs at 28,800 vibrations per hour and a power reserve of 65-hour. The movement has 235 parts.

Master Geographic  Reference Q1428530

The Master Geographic is the emblematic model of the Master Control collection, providing travellers with a novel way of reading the second time zone. The aperture in the lower section of the dial displays the names of 24 world cities, representing all the time zones. A crown set at 10 o'clock on the case makes adjusting the indicator of this second time zone simplicity itself. Patterned in a circular guilloche that catches light from a different slant, the indicator contrasts elegantly with the other finishes on the dial. With its signature blue colour, the design brings a fresh feel to this watch, without taking away from its classic sobriety.

Inside the 39 mm case is an automatic mechanical movement, Jaeger-LeCoultre Calibre 939B/1, wich runs at 28,800 vibrations per hour.

The Master Geographic  has a 43-hour power reserve.

"1000 Hours Control" at the heart of the Master collection for 25 years.

Master Control was the first Jaeger-LeCoultre line to benefit from the "1000 Hours Control" in-house certification, which inspired its name. This series of radical tests to ensure that the watches are reliable has since been extended to all of the Grande Maison's models. Watches are tested in six positions during the six-week testing period, to reproduce the conditions they will be worn under. Temperature variations, accidental impacts, power reserve capacity, water resistance - nothing is left to chance, ensuring the future owner of the piece will be fully satisfied with it.
