On the new watch from Jaeger-LeCoultre , the strange and fascinating meteorite stone used for the dial shakes up the traditionally pure, understated aesthetic of the Master Calendar. Composed of a single block of meteorite discovered and officially registered in Sweden, it comes from the asteroid belt between Mars and Jupiter.
To get an aesthetically perfect dial, this block of meteorite is cut into several thin plates in a process involving countless precautions, until the exact plate corresponding to the demands imposed by Jaeger-LeCoultre is achieved. After this, the meteorite must undergo several preparatory phases before revealing the structure of its stone that features a unique pattern shown by each cut.
Representing the iconic calendar complication, the complete calendar of the Master Calendar model displays the date by means of a long hand tipped with a moon crescent sweeping around a scale around the dial rim graduated from 1 to 31. It also indicates the day of the week and the month in twin apertures at 12 o’clock. Featured on certain Renaissance pocket watches before being more widely used in the 19th century, this numerical display principle serves to catch attention and focus it firmly on the present.
The complete calendar indicates the various moon phases – new moon, first quarter, full moon and last quarter – in the traditional form of this emblematic heavenly body emerging from between two clouds and rising up against a star-studded sky.
The cleverly mastered dial architecture ensures immediate and pleasing readings of the information, with hours and minutes shown by dauphine hands and small seconds at 6 o’clock.
With a 39 mm-diameter, this10.6 mm-thick case is designed to adapt to the curve of any wrist. The sapphire crystal case-back of the Master Calendar reveals the intricate workings of Jaeger-LeCoultre Calibre 866 and its delicate finishes.
