Jaquet Droz reimagines its Grande Seconde Moon

Buoyed by the success of the first Grande Seconde Moon collection, Jaquet Droz has released four new versions of the astronomical moonphase watch that combine gold, steel, grand feu enamel and aventurine.

If watchmakers are in eternal pursuit of the perfect circle, the Grande Seconde Moon comes very close to achieving that goal. The brand’s signature figure 8 dial incorporates a Moon Phase with date nestled inside the perfect geometry of the off-centered large seconds hand at 6 o’clock. The new Grande Seconde Moon combines the day-to-day practicality of precise hour, minute, seconds and date displays with the poetry of a 22-carat gold Moon Phase.

Jaquet Droz first took on the aesthetic challenge of incorporating this complication into the Grande Seconde watch with the initial Grande Seconde Moon collection released in 2017. By playing with proportions and materials, the brand managed to preserve the time-honored design created by Pierre Jaquet-Droz 280 years previously while enhancing it with the poetry the Moon deserved.

This initial lunar take on the iconic model was received to great acclaim. Comforted by this success, the collection is expanding. Two new light-colored variations – a 43mm white gold model with Grand Feu enamel dial, and a 39mm steel model with opaline dial – feature a blued steel Moon disc decorated with 18-carat white gold star appliques. Two further interpretations exhibit a more mysterious color palette: a 43mm red gold model with black Grand Feu enamel dial presents a black onyx disc, while a 39mm diamond-set steel model boasts an aventurine dial and disc.

Since the Moon Phase requires a greater level of precision, Jaquet Droz developed Mechanism 135, an in-house movement featuring a high precision 135-tooth wheel inside a Jaquet Droz 2660QL3 caliber. While a traditional 59-tooth movement accumulates an error of one day every two years and eight months, the Jaquet Droz Moon Phase need only be adjusted by one day every 122 years thanks to a corrector discreetly incorporated into the middle of the case. The precision of the Grande Seconde Moon movement is thus infinitely closer to the actual lunar month which lasts exactly 29 days, 12 hours, 44 minutes and 2.8 seconds.
