Jaeger-LeCoultre’s Master Ultra Thin timepieces need little introduction in the realms of high horology. As dubbed in the name, the most classic collection of the traditional Maison is distinguished by slim cases, sophisticated dials and, most importantly, bespoke movements entirely designed and produced in-house. It comprises of some of the most sought-after complications, grand and small, in gold and stainless steel cases.
Among them is the Master Ultra Thin Perpetual Calendar, which is unveiled in a new generation at this year’s Watches and Wonders. The latest executions feature a subtly modernized case and dial design, as well as a significantly increased power reserve thanks to the evolution of the self-winding caliber 868. The extended power reserve is very useful in a caliber with such complex indications, allowing the wearer to put the watch away for a whole weekend and wear it again on Monday without having to correct any of the indications. If necessary, however, they can be adjusted by means of a single corrector set in the side of the case. It goes without saying that the movement, which is equipped with a partially skeletonized rotor, is finished and decorated to high standards, such as perlage on the main plate, meticulous beveling of the angles and Geneva Stripes as well as blued screws.
In the world of watchmaking, where sizes and proportions are miniature, sometimes microscopic, small changes often make a big difference. Difficult to measure, they have an immediate impact with a “wow” effect. It really is a bit like magic. This rings also true for the new Master Ultra Thin Perpetual Calendar whose case has been subtly reworked while maintaining the same proportions as the original Master Ultra Thin Perpetual Calendar, with an elegant diameter of 39mm and a svelte height of 9.2 mm.
The dial design has also been modified, while retaining all the symmetry and balance of the earlier layout. Refined sub dials highlight the indications, making them even more legible than before; the starry sky of the moon phase display is more intricate; the applied hour markers have been elongated; and each facet of the Dauphine hands has a different finish, polished or satin.
The steel version of the Jaeger-LeCoultre Master Ultra Thin Perpetual Calendar that comes with a silver dial retails for approximately $33,000 when converted to USD. The pink gold variant, equipped with an eggshell-hued dial has a sticker price of approximately $47,400 when converted to USD. The diamond-studded model in pink gold retails for approximately $55,800 when converted to USD.
