Who Sells The Best Jaeger-LeCoultre – 25 years of Master Control Eta Movement Replica Watches

Posted by

A quarter of a century ! Albeit modest on the scale of watchmaking history, this longevity nonetheless conveys authentic recognition among devotees of Fine Watchmaking, while representing an important proven guarantee of continuity for a collection that has shown itself capable of keeping step with the times – and particular with its enthusiasts.

Introduced at the SIHH 2017, this year’s Master Control vintage comes in three models : Date, Geographic (picture above), as well as the Chronograph starring on the cover of this GMT winter edition. Last year at the same time, we had headlined our magazine with the Master Memovox Boutique Edition, whose blue color had gained a broad following well beyond our circle of readers. While still omnipresent on the alligator strap, blue no longer dominates the dial, instead appearing as distinctive accents that make this new version immediately identifiable, notably on its cut-out baton-type hands evoking the skyline of Manhattan. It adopts a softer shade on the tachymeter scale and the two 30-minute and 12-hour counters, playfully and subtly embedded in the central railtrack circle displaying the hourmarkers. A discreet vintage spirit pervades this elegant timepiece.

Each watch has a face, and that of the Master Control Chronograph wears a sincere smile – while remaining paradoxically sure of its serious reliability. Like all the models in what became a cult collection right from the start, it proudly bears the “1000 hours Control” seal, signifying that it has successfully undergone six weeks of testing in six positions aimed at challenging its resistance and its performance.

The big-date display, which can be patented, functions by means of a “ones” ring bearing the digits 0 through 9 and a “a huge number” cross with the digits 1 through 3 and a blank field. A unique challenge for the engineers would be to make sure that the calendar switched correctly at the ends of months with 31 days. For all those months, the “ones” ring needs to stay motionless during the night preceding the first of the new month, while the “tens of thousands” cross legged through 90 degrees to deliver its blank section into view. Lange & Söhne released its first self-winding watch, the Langematik, three years later it launched the Lange 1. To raise the movement’s winding efficiency, the solid gold strand in the Langematik is equipped with an outer platinum section. A reverser mechanism allows the rotor to convey energy into the mainspring in the two directions of rotation. To minimize friction, Lange’s watchmakers added three micro ball bearings into the reduction gearing.

The two convenient and user-friendly pushpieces framing the screw-lock crown leave no doubt as to their role, which is to trigger the chronograph functions of the automatic caliber developed in the firm’s Le Sentierbased Manufacture. It is fortunately not engaged in a race against time. A last useful note for couples who like to share everything : they can express this penchant through a case designed to suit both men’s and women’s wrists. Happy anniversary !
