Jaeger-LeCoultre Master Ultra Thin Perpetual Calendar Moonphase

Most are no doubt familiar with Jaeger-LeCoultre via the famed Reverso. But that’s not La Grand Maison’s entire story.

The dynamic Swiss watchmaking powerhouse is responsible for myriad iconic designs,  from reversible dress watches to alarm-equipped dive watches, complicated, hand-enameled masterpieces and much, much more. Indeed, the storied company from Le Sentier has one of the most diverse offerings in fine watchmaking. For generations, Jaeger-LeCoultre have been referred to as 'The watchmaker's watchmaker', for they not only supply numerous other brands with components, contract manufacturing, and know-how - but they are also the brand of choice to wear for many of the world's leading watchmakers.

Their 'Master' line of Perpetual Calendars stand as a prime example of why LeCoultre's proficiency in watchmaking translates so well to a commercial-grade product. They are incredibly well-designed, engineered, and executed - and they also represent one of the best values in high horology.

What make this perpetual calendar so special? Imagine a watch that keeps track of not only the time, but also the date, the day of the week, and the month, tells you whether it’s a leap year or not, and informs you what the current phase of the moon is. Oh, and one more thing — imagine it does all of this mechanically, using springs and gears, and that you only have to adjust it once every century or so. Crazy, right?

The particular example, a Master Ultra Thin Reference Q1308470 comes from their current lineup. It features a 39mm stainless steel case with a sapphire crystal, a polished bezel, a signed crown, and a lovely satin black dial with applied 'dart' indices and a matching 'dauphine' handset with year and moonphase apertures.

Powered by JLC's Calibre 868 automatic-winding perpetual calendar movement — visible through a sapphire exhibition caseback — this piece comes fitted to a signed, black alligator strap with a signed steel deployant clasp. This example also comes complete with its inner and outer box set, books, corrector tool, and a warranty card dated 2022.

The Master Ultra Thin Perpetual Calendar Moonphase is the perfect daily-wearable haute horology timepiece from one of the best manufactures in the game!

Few watchmaking concerns are as storied as Jaeger-LeCoultre. Though the maison is not technically a member of the “Holy Trinity” of Patek Philippe, Audemars Piguet, and Vacheron Constantin, one could easily make the argument that it should be: After all, it was JLC that supplied movements to Patek from the beginning of the 20th century through the early 30s.

Founded in 1833 by Antoine LeCoutlre in Le Sentier, Switzerland, the firm became the Jaeger-LeCoultre we know today when it merged with Parisian watchmaker Edmond Jaeger’s business in 1937. The two horological concerns collaborated on numerous projects before cementing their partnership, the most important of which was no doubt the Reverso. A sport watch with a reversible case, this ingenious timepiece was designed to offer protection to the watch dial — when engaged in sport or otherwise dangerous activity, the wearer would simply flip the case over, exposing its back to the world, rather than the vulnerable crystal.

But the Reverso is far from the only significant timepiece brought to market by JLC: The firm also produced the world’s thinnest pocket watch in 1907, powered by the Caliber 145. In 1929, the maison released the Caliber 101, still today the smallest mechanical movement. (Queen Elizabeth II wore a Caliber 101-equipped wristwatch to her coronation in 1953.) And perhaps no other watchmaker is world-renowned for their production of a clock in the way that JLC is famous for the Atmos. Invented by Jean-Léon Reutter, it’s powered by miniscule changes in atmospheric pressure — Edmon Jaeger acquired the patent and licensed it beginning in 1936. The Atmos is still produced in numerous forms today, and remains the Swiss government’s foremost diplomatic gift.

From classic, near-centuries old designs like the Reverso and the Atmos to modern über-complications such as the brilliant Master Gyrotourbillon, Jaeger-LeCoultre remains on the cutting edge of horological technology nearly two centuries after its founding.
