This year, Jaquet Droz celebrates the 300th birthday of its watchmaking founder with the reimagined variant of the Grande Seconde Moon watch. The Grande Seconde Moon 300th Anniversary Edition comes in two exclusive alternatives: one explores the traditions of the Maison and the other explores its modern inspirations.
Based on a figure “8” design, the Grande Seconde organizes time in a unique way, with off-centered hours and minutes at the top, complemented by a large seconds dial at 6 o’clock. The Grande Seconde Moon, which has previously been available in 43 mm and 39 mm versions, comes, for the first time, in a contemporary 41 mm diameter, suitable for both men’s and women’s wrists.
The first piece celebrates the legacy of Pierre Jaquet-Droz and embodies the traditional aspects of the Maison. It is fitted with an ivory Grand Feu enamel dial, a signature of the Maison’s expertise, with Roman numerals for the hours and minutes, and Arabic numerals for the seconds, all in the purest traditional spirit of the Grande Seconde. It comes on a midnight blue strap, representing the starry sky that reveals the Moon.
The second piece features a matte black dial in an intense, dark astral variation, which reveals the Moon Phase. Arabic and Roman numerals are replaced by red gold indexes. This modern look is emphasized by a hand-made strap in matte black calfskin. With a truly contemporary approach, Jaquet Droz has designed a new Grande Seconde Moon with only two tones, where the brightness of the red gold is matched only by the depth of the intense black.
Two models of the Grande Seconde Moon 300th Anniversary edition feature an 18K red gold case, which houses the 2660QL4 self-winding movement, with a 68-hour power reserve, as well as a silicon balance spring and pallet lugs. Jaquet Droz has fitted it with an in-house development that gives its Moon Phase unparalleled accuracy. Known as the Mechanism 135, it reduces the usual margins of error of the Moon Phase display and only requires a single adjustment every 122 years. This is as close as possible to a real synodic revolution (29 days, 12 hours and 45 minutes for the Grande Seconde Moon, for an actual revolution of 29 days, 12 hours, 44 minutes and 2.8 seconds), this Mechanism 135, resting on a 135-tooth lunar disk (instead of the usual 59) guarantees the piece an age-old precision that can be adjusted with a stylus, using an invisible corrector hidden in the case at 8 o’clock.
Each version is hand-engraved with “Pierre Jaquet-Droz, 300ème Anniversaire” on the back.
