Jaquet Droz has revived the Grande Seconde Moon, adding a new lunar edition to the collection.
There has already been a Silvery version of the Grande Seconde Moon, meaning Jaquet Droz has now decided to serve it up in Anthracite.
Designers say that it is not just another shade of grey, but a slight chromatic shift considerably which changes how the watch is perceived.
This dial is sandblasted, which makes it more vivid, striking and allows it to casts a striking resemblance to the surface of the moon.
The lunar display sits poised at 6 o’clock as the large seconds hand and perpetual date hand fly over it. With the utmost regard to watchmaking tradition, these hands are blued, as are those marking the hours and minutes.
Six white gold stars strike forth against the solid background as a subtle nod to the Jaquet Droz two-star emblem and they are joined by the white gold moon, which was drawn by hand to capture its naturally cratered surface, moved by a so-called ‘astronomical’ Moon Phase.
It is powered by a new movement called Mechanism 135 that runs with a 135-tooth wheel. While a traditional 59-tooth movement accumulates an error of one day every 2 years, 7 months and 20 days, the Jaquet Droz Moon Phase only requires a single adjustment every 122 years and 46 days.
The movement’s precision is thus closer to the actual lunar month: 29 days, 12 hours, 44 minutes, 2.8 seconds.
The 43 mm steel case features a sapphire crystal back designed for admiring the movement’s Côtes de Genève finishes and openwork Sunray finished oscillating weight.
With a double barrel enabling the 68-hour power reserve, this Jaquet Droz 2660QL3 self-winding mechanical movement has a silicon balance spring and pallet lugs, making it virtually impervious to magnetic fields and temperature fluctuations.
