Jaeger-LeCoultre Master Control Chronograph Calendar

The Jaeger-LeCoultre Master Control Chronograph Calendar is a recent addition to the luxury brand’s collection. With an impressive inventory of functions and, most notably, an über-refined chronograph, this long-established Maison has produced another masterpiece.

Jaeger-LeCoultre Master Control Chronograph Calendar

Jaeger-LeCoultre was founded in 1833 in the Vallée de Joux, a region synonymous with harsh winters and fine watchmaking. The company has always been mentioned in reverential tones. Renowned for making movements, including ultra-thin calibres and high complications, Jaeger-LeCoultre has supplied the great and the good of the watch industry.

In the past, many historical Maisons were établisseurs, procuring ébauches and other components from specialist companies such as Jaeger-LeCoultre. The établisseurs would decorate, assembly and regulate the movement.

At the heart of this venerated company is a high quotient of ingenuity, evidenced by the numerous patents the company holds; approximately 400 at the last count. Having produced over 1200 different calibres, surpassing any rival, the engineering prowess of JLC is manifest.

Jaeger-LeCoultre’s talents go beyond making movements. It has a well-developed sense of style, creating an array of eye-catching models, perhaps most notably, the legendary Reverso dating back to 1931. The design of this watch wholeheartedly embraced the Art Deco movement prevalent at the time. However, while the Reverso was designed in the past, its appearance remains timeless.

Recently, the brand from Le Sentier unveiled the Jaeger-LeCoultre Master Control Chronograph Calendar. This model, upholding the brand’s fondness for complications, features a calendar with date, day and month indications as well as a moon phase and a chronograph.

However, this is no ordinary chronograph, it features a column wheel with vertical coupling. This combination is the purist’s choice. When actuated, the central chronograph seconds hand commences its journey without hesitation or stuttering. Furthermore, the movement is less susceptible to wear. Lastly, when some chronographs are running, the movement can suffer ‘drag’, where the amplitude of the balance falls, adversely affecting precision. With a vertical coupling this is virtually eradicated.

Without further ado, I present the Jaeger-LeCoultre Master Control Chronograph Calendar.

The brand’s press release

The headline model of the new Master Control collection features a newly developed movement, Calibre 759, which combines a chronograph with a triple calendar display and a moon-phase. Brought together for the first time in a Jaeger-LeCoultre timepiece, this alliance of complications evokes the ancient links between watchmaking and astronomy. The new Calibre 759 features a column-wheel chronograph with a vertical clutch, a moon-phase indicator, and a 65-hour power reserve.

With a balanced dial layout that combines the familiarity of two classical complications – a triple calendar and a bi-compax chronograph – Jaeger-LeCoultre’s designers have made the reading of the displays straightforward and intuitive, despite the complexity of the information shown. The 30-minute chronograph counter at 3 o’clock is balanced by the running seconds subdial at 9 o’clock, while the day and month windows in the top part of dial are balanced by the moon-phase and date indicator at 6 o’clock. The entire display is anchored by the central chronograph seconds hand and contained by the pulsometric scale marked around the dial flange. Complementing the Chronograph Calendar’s timeless style, rectangular chronograph pushers add a purposeful, modern air to the well-proportioned 12.05mm thick case, which is offered in steel or Le Grand Rose gold®.
