It is now in stores the new Quantieme Perpetuel Eclipse from Jaquet Droz, a fascinating timepiece which pairs the the moon phase complication with a perpetual calendar.
At 12 o’clock, a single-hand counter indicates the month with the leap year appearing in a small window. At 6 o’clock, a black or ivory-colored onyx index moves across the face of a golden moon, revealing, and then concealing it until its total eclipse, hence the name of the watch.
The pink gold case has a diameter of 43 mm with a thickness of 13.20 mm.
The self-winding movement - beating at a frequency of 28,800 vibrations per hour - offers a power reserve of 68 hours.
