SIHH Report: Jaeger-LeCoultre Introduces New Era of Ultra-Thin Grand Complications

Master Ultra Thin Minute Repeater Flying Tourbillon_In 1907, an association between Swiss watchmaker Jacques-David LeCoultre and Paris-based businessman Edmond Jaeger gave birth to the world’s thinnest pocket watch featuring a blend of aesthetic refinement and horological sophistication that only a manufacture uniting the full range of skills under one roof could hope to achieve.

Today, Jaeger-LeCoultre confirms its ability to anticipate the future of fine watchmaking by unveiling the Master Ultra Thin Minute Repeater Flying Tourbillon watch, the eleventh creation in the Hybris Mechanica collection and the first ultra-thin grand complication model.

Think-tanks composed of insatiable visionaries and tireless developers: such is the very nature of the teams at Manufacture Jaeger-LeCoultre. It enables them, just one year after the introduction of the Master Ultra Thin Jubilee, to present an authentic pioneer in the field of Grand Complications.

The newcomer bears a name revealing a set of technical feats that are bound to stimulate the imagination of fine watchmaking connoisseurs. And rightly so. The Master Ultra Thin Minute Repeater Flying Tourbillon stems from research on two iconic horological complications. It is indeed the slimmest minute repeater in its category at just 7.9mm thin.

This watch capitalises on eight separate patents, six of which are entirely new. Its entire development process was governed by two watchwords – ingenuity and performance. Its quintessence lies in a successful bid to achieve extreme slenderness while making no compromises on reliability.

Hybris Mechanica 11 is equipped with an original tourbillon, a high-performance new balance-spring, a peripheral automatic winding system, a retractable single pushbutton, as well as a new minute repeater equipped with a silent-timelapse reduction system. As the latest addition to an illustrious and fertile saga of Jaeger-LeCoultre striking watches, this model consolidates the brand’s leadership in this field.

Hybris Mechanica 11 watch resolutely confirms that excellence and surpassing existing limits are second nature to Jaeger-LeCoultre. Driven by such strong convictions, Hybris Mechanica 11 places the Swiss watchmaker firmly at the very pinnacle of ultra-thin horology and grand complications.
