At the Watches & Wonders in Geneva, Jaeger LeCoultre presented three new models, in which each is an expression of what the Le Sentier maison is able to achieve both in the mechanical and decorative fields. We are talking about the Master Grande Tradition 948, the Master Hybris Artistica 945 and the Polaris Perpetual Calendar.

MASTER GRANDE TRADITION CALIBER 948

Let's start with the Master Grande Tradition 948, where for the first time the complication of the world hours was combined with a flying tourbillon.

The dial reflects the complexity of this internal mechanism. In the center is a map of the world seen from the North Pole. Instead of using a traditional flat Earth image, this domed map soars above the dial and, together with the universal tourbillon and city ring, makes a full 360-degree revolution every 24 hours to display the correct time in each zone.

Under the dome, which represents the oceans, the dial is a vivid blue translucent lacquer disc applied to a wavy guilloche pattern that suggests the movement of the sea and the lunar influence on the tides. In a circular opening on one side of the map, the flying tourbillon appears to float above the blue oceans, spinning in 60 seconds.

The Master Grande Tradition 948 is a limited edition of only 20 pieces. The 43mm x 14,13mm white gold case of the Master Grande Tradition is made up of more than 80 parts, with a convex bezel, wide bevels on the lugs and hollowed lugs sides that create a dynamic silhouette. Micro-sandblasted, smooth and contrasting satin surfaces create a pleasant play of light. It is presented on an alligator leather strap with a folding clasp.

MASTER HYBRIS ARTISTIC CALIBER 945

Jaeger-LeCoultre has reinterpreted its Grande Complication Caliber 945 with two new additions: the Master Hybris Artistica Caliber 945 Galaxia in rose gold and the Master Hybris Artistica Caliber 945 Atomium in white gold. Both are limited to five pieces each.

Watchmakers have developed a mechanism capable of visualizing the passage of sidereal time, based on the stars. With a duration of exactly 23 hours, 56 minutes and 4,1 seconds, a sidereal day is defined by the Earth's rotation measured in relation to the most distant fixed stars, while the 24-hour solar day - our civil time - is measured by the Earth's orbit around the sun. Located in the center of the quadrant, the celestial vault maps the night sky of the northern hemisphere as seen from the 46th parallel - the latitude corresponding to the Jaeger-LeCoultre headquarters in the Vallée de Joux - by plotting the position of the constellations in real time.

These specimens also provide a philosophical perspective by showcasing Jaeger-LeCoultre's mastery in decorative craftsmanship. The movement of the Master Hybris Artistica Caliber 945 includes a celestial card with a celestial vault, a zodiac calendar, a minute repeater - the incredible power of sound and clarity of the gongas - and the Cosmotourbillon by Jaeger-LeCoultre decorated by hand by the artisans of the Métiers Rares .

POLARIS PERPETUAL CALENDAR

The perpetual calendar is considered to be one of the most complex watchmaking complications to master. The new Polaris Perpetual Calendar was presented in both rose gold and steel. Under the sapphire crystal caseback, the new Jaeger-LeCoultre Caliber 868 designed, produced and assembled in-house reveals its 351 components.

Conceived as an everyday watch, the Polaris Perpetual Calendar elegantly displays the correct date. Inside, Caliber 868AA - a new version of the QP movement that first appeared in 2013 - automatically adjusts to these discrepancies and will not require manual correction until 2100. Additionally, using the latest manufacturing technology, the Caliber 868AA allows for a retrograde display of the phases of the moon, as viewed from the southern hemisphere.

Another useful feature is the small safety zone indicator in the center of the dial.
This window is red to warn the user not to adjust the time or calendar indications between 20:00 and 04:00.

The innovations embodied in this movement include a moon phase indicator in both hemispheres, with a retrograde hand for the southern hemisphere. Enhanced by the rose gold bezel and lugs, the lacquered dial features extraordinary shades of blue tones. The luminescent hands and indexes stand out against this ocean blue, along with the perpetual calendar and moon phases. The Polaris Perpetual Calendar is supplied with a pair of easily interchangeable straps: one in blue rubber, the other in black alligator with folding clasp.

Both models have a 42mm case. And while the steel edition is offered with both a steel three-link bracelet and a textured rubber strap, the rose gold version comes with a sporty blue rubber strap and an alligator strap with a folding clasp.
