In 2017, Jaquet Droz integrated a moon phase complication into one of its most emblematic models, the Grande Seconde.
The main challenge for Jaquet Droz watchmakers in the integration of the moon phase display was maintaining the key elements of the dial and, in particular, the purity of the two interlaced dials which form a figure eight, the symbol of completion and plenitude.
For its Grande Seconde Moon, Jaquet Droz chose a so-called astronomical moon phase, requiring adjustment only once every 122 years and 46 days. Thanks to its carefully studied gear ratio, the specially developed "mechanism 135" is much more precise than a traditional 59-tooth model, which accumulates an error of one day in approximately two years, 7 months and 20 days.
The finishes of the different versions available are excellent: from the brilliance of silvery opaline to the deep black of onyx, up to the precious ivory Grand Feu enamel.
Located at the heart of the lower dial dedicated to the date with a direct-drive seconds hand, the moon disc is made of onyx in the black version and blued steel in the other two models. In both cases tiny gold stars shimmer on the dark background.
Each day, the moon disc rotates clockwise faithfully representing the moon’s cycle. Readability is perfect thanks to a specially designed double-level dial. A corrector positioned at 8 o’clock enables the owner to set and adjust the moon phase with a simple push of the stylus that accompanies the timepiece.
The 43 mm case comes in stainless steel or in red gold for the ivory enamel version which is adorned with an applied satin-finish red gold circular ring. Water resistance is 30 metres / 100 feet.
The self-winding Jaquet Droz 2660QL3 mechanical movement with silicon balance spring and pallet horns beats at 4 Hz (28,800 vibrations per hour). Its double barrel offers a power reserve of 68 hours.
