Description

Jaeger-LeCoultre has unveiled the Duomètre à Quantième Lunaire in an exclusive limited edition of just 200 pieces, marking a significant achievement in the world of haute horlogerie. Building on the legacy of the Duomètre Chronograph, the first watch to feature the Dual-Wing movement, this new model carries forward the innovative concept first introduced in 2007. Instead of a chronograph, the Quantième Lunaire offers an exquisite date and moonphase function, all powered by the same groundbreaking Dual-Wing system.

The Dual-Wing movement in this timepiece is a marvel of engineering, featuring two separate power supplies. One power supply is entirely dedicated to displaying the time—hours, minutes, seconds—as well as the date and moonphase. The second power supply is devoted to the escapement and balance, ensuring consistent and precise timekeeping. These two systems are harmonized by the jumping seconds hand mechanism (foudroyante), driven by the escapement, guaranteeing unparalleled accuracy.

Housed in a 42 mm case of polished and brushed 18k white gold, the Duomètre à Quantième Lunaire exudes sophistication. The matte black dial, with applied numerals, is paired with a matte black alligator leather strap and an 18k white gold folding clasp, creating a striking contrast that highlights the watch’s elegance. The series number is proudly displayed at 6 o’clock, underscoring its exclusivity.

At the heart of this masterpiece is the Jaeger-LeCoultre Calibre 381, an in-house movement that epitomizes precision. It features a large 10 mm balance wheel with an inertia of 11.5 mg cm², beating at a frequency of 21,600 vibrations per hour (3 Hz). The movement is divided into two sections, each with its own barrel and mainspring, ensuring a power reserve of 50 hours. One barrel powers the hours, minutes, seconds, jumping seconds, date, and moonphase, while the other is dedicated to the escapement, ensuring a constant power supply for precise timekeeping.

Winding the watch is a seamless experience: rotating the crown counterclockwise winds the timing barrel (escapement), while rotating it clockwise winds the power reserve for the functions.

The Duomètre à Quantième Lunaire is a testament to Jaeger-LeCoultre’s commitment to precision and innovation. The unique Dual-Wing Jaeger-LeCoultre Calibre 381 elevates the timepiece to a new level of accuracy, setting a benchmark in the realm of complicated watches. This limited edition is not just a watch; it is a celebration of the highest standards of mechanical excellence.

Jaeger-LeCoultre – Bio

Jaeger-LeCoultre has been at the forefront of inventions throughout its history, right from the beginning in 1803, when the founder Antoine LeCoutre invented a machine to cut watch pinions from steel. The brand was established in 1833, and years later in 1937, a Paris-based watchmaker Edmond Jaeger joins LeCoutre to form Jaeger-LeCoutre. The duo continue to produce some astonishing movements, spread over 1300 calibers and counting.
Through the years, watchmakers such as Patek Philippe, Audemars Piguet and Vacheron Constantin have used the company’s movements.
