Jaeger-LeCoultre Master Control: look who’s here

Even if we assume that the aesthetic credo of Jaeger-LeCoultre Master Control is expressed in the rectangular Reverso watch in an inverted case, the value of the Master collection, uniting round models, is still great.

Firstly, it is one of the long-livers (produced since 1992), who have formed the idea that watches of this brand can have a form factor different from the canonical Reverso.

Secondly, it is abundant (50 models on the official website of the manufacture) and includes three lines: the basic Master Control, models with ultra-thin Master Ultra Thin movements and the complex Master Grande Tradition watch.

Jaeger-LeCoultre Master Control Date

At the end of April, four updated models of the Master Control line were presented using the Watches & Wonders virtual platform, one of which had no predecessor in the model range before.

In fact, there are six new products, but images of models with alarms – Master Control Memovox and a limited edition of 250 copies of the boutique version of Master Control Memovox Timer – are not available on the platform.

What do all the new Master Control 2020 products have in common? Let’s start with the mechanisms. The in-house automatic calibers have been thoroughly redesigned: while maintaining the previous factory indexes, they received silicon escapement assemblies.

This allowed them to minimize friction and reduce energy consumption. The revised wheel of the central second hand eliminated the vibrations.

Udated JLC 939 Caliber

Titenium is the material for the rotor mounting screws, not steel. The barrel has lost its lid and accommodates a more elastic and longer spring, which increases the power reserve up to 70 hours (previously: 40-43 hours, depending on the caliber).

Jaeger-LeCoultre Master Control Chronograph Calendar

The cases, which are waterproof up to 50 m, have grown by 1 mm (earlier the case diameter was 39 mm, now it is 40 mm) and slightly changed in thickness. The silvery-white background of the dials is enlivened by the sunburst pattern.

The dauphine style hour and minute hands are made of silver steel or rose gold (depending on the case material), while blued counter hands draw the eye towards additional indicators. For gold cases, a new alloy of Le Grand Rose rose gold with a high content of palladium has been used, which protects the precious metal from oxidation.

Easily removable straps made of soft matte Novonappa calfskin leather in light brown that takes over the steel models, giving the watch a vintage charm. The gold versions still use the classic alligator chocolate brown straps.

Few More Words

The updated Master Control looks good in the images. Only the calfskin straps cause slight rejection: it seems that they are slightly cheaper than the watch. The traditional alligator looked more impressive.

Just a few words about the previous models, which faded away by new items. We loved the trio launched in 2017 for the 25th anniversary of the Master Control collection: Date, Géographique and Chronograph with gray sector dials.

Now they are out of production, but they are still in stock. Their release is not limited, so they are unlikely to turn into rarities, but we strongly recommend these anniversary models as great examples of the Jaeger-LeCoultre signature style.

Price

Specifically, the Master Control Date, a three-hand instrument with a date display opens the model hierarchy. This is the only new product that is available only in a steel case. Its thickness is 8.78 mm (previously 8.5 mm). Altogether, it costs around: $8,506 USD.

Jaeger-LeCoultre Master Control Calendar

In short, Master Control Calendar is a clock with a triple (full) calendar showing the value of the date, day of the week, month, and moon phase. Every month the hand of the date indicator jumps 90 ° from “15” to “16” so as not to obscure the lunar phase indicator and the dial of the small second’s hand.

Price

The Le Grand Rose steel or gold case is 10.95 mm thick (previously it was 10.6 mm). The steel version costs$13,854. The gold version costs about $27,951 USD.

Jaeger-LeCoultre Master Control Géographique

The name Géographique in the corporate terminology denotes a watch with a second time zone function. But they are not equipped with a simple GMT-hour hand, but are close to the “world-timers” – watches with a world time function.

At the bottom of the dial, there is a window for a disk with the names of cities representing different time zones of the Earth, and the sub-dial of the second time zone at 6 o’clock is served by two hands – hour and minute, which makes it possible to set the local time in zones with a difference that is not multiple hours (for example, in India or Iran), and is also supplemented by a “day/night” indicator.

Le Grand Rose Alloy

The date and power reserve indicators visually balance the sophisticated functionality. However, the Master Control Géographique comes in new, flatter cases with a thickness of 10.96 mm (previously 11.77 mm) made of steel or Le Grand Rose alloy and costs about the same as the Master Control Calendar model.
