Jaquet Droz Grande Seconde Moon Argentee

Within its dial in the form of an “8”, the Maison added a Moon Phase and date function, both rolled into the perfect geometry of the large off-centre seconds feature at 6 o’clock. The new “Grande Seconde Moon” thus combines the precision of the most useful daily indicators (hours, minutes, seconds, date) with the poetry of a Moon Phase. The integration of this mechanism into the Grande Second posed an aesthetic challenge. The challenge was to preserve the secular drawing invented by Pierre Jaquet-Droz 280 years ago by adding the poetry of a moon, which displays a new face every day. To achieve this, Jaquet Droz played on volumes and materials, finishes and colours, to create a coherent, readable and soft aesthetic.

To bring his Moon Phase to life, Jaquet Droz designed a mechanism with rare precision. This movement is the result of a Maison development known as “mechanism 135”, driven by a 135-tooth wheel integrated within the Jaquet Droz 2660QL3 calibre. While a traditional movement with a 59-tooth wheel accumulates an error of one day every 2 years and 8 months, the Jaquet Droz Moon Phase will only require a manual adjustment of one day every 122 years, thanks to a corrector, discretely nestled into the case. The precision of Grande Second Moon’s movement is thus infinitely closer to the real lunar revolutions, exactly 29 days, 12 hours, 44 minutes and 2.8 seconds.
