Jaeger-LeCoultre Reverso Quantième Calendrier Perpétuel

The Reverso Quantième Calendrier Perpétuel was a limited-edition luxury perpetual calendar watch by Jaeger-LeCoultre introduced in 2000. It was part of the Reverso family's Reverso Complications series, and the first Reverso with this complication.


In 1991, Jaeger-LeCoultre re-established itself as a high-end watchmaker, adding a complication to the iconic Reverso range as a signature piece. The resulting Reverso 60eme showed what could be done in the tiny reversible Reverso case, adding a power reserve indicator and date by pointer to a larger “Grande Taille” case with a display caseback. These elements were taken to a new level with the Reverso Tourbillon, Reverso Répétition Minutes, and Reverso Chronographe Rétrograde, and Reverso Géographique that followed.

The Reverso Date model, introduced in 1998, added the familiar calendar complication to the Reverso range. So it was natural that Jaeger-LeCoultre would take on the challenge of a perpetual calendar for the Complications series. The Reverso Quantième Calendrier Perpétuel appeared in 2000 and adds a perpetual calendar movement to the compact Reverso case.

The front dial displays the time with small seconds as well as a day/night indicator at 1 00. The dial is guilloche, as typical of Reverso models, with Arabic numerals for 3, 4, and 8-11 with the “JL” anchor logo at 12 00. Below the seconds subdial is a leap year indicator, suggesting the unique complication within. The back dial shows the calendar with a central retrograde hand for the date and a central moon phase indicator with numbering from 0 to 29 1/2. Below are two subdials Month (with alternating French abbreviations) and day (also in abbreviated French). Correctors inset at all four corners allow the calendar to be adjusted.

Once again a limited edition of 500, the Quantième Calendrier Perpétuel features a pink gold case in the Grande Taille size, 42 mm tall by 26 mm wide. The movement, Cal. 855, was only used in this model.

Like the rest of the Reverso Complications models, this watch is a forerunner of the Hybris Mechanica line thanks to its custom complicated movement. It was the final of six rose gold limited-edition complicated Reverso models, with the next offering being the Reverso Platinum Number One.
