At this year’s Baselworld, Jaquet Droz plays it elegant and sophisticated with understated yet classy styles. Among the new pieces unveiled, the Grande Seconde Moon especially caught our attention. Some might already know the Grande Seconde and its distinctive look, but here it features a new complication : the moon phase. Even though the overall aesthetics remain similar to the previous models, the moon phase really adds a new dimension to the watch. A visual dimension but also a spiritual one, considering the lyrical nature of this complication.

Jaquet Droz aims for the moon with the new Grande Seconde Moon

The brand known by its twin stars took everything that makes the Grande Seconde great and perfectly added the moon phase indication to it. The refined dial remains true to the silhouette of the watch and features the classic interlaced 8-shaped subdials, Jaquet Droz’s lucky number. The off-centered hour and minutes dial at 12 o’clock meets the 6 o’clock date and running seconds dial. The moon disc is cleverly fitted in the latter. While the running seconds are on the outside circle, the date is located on the inner circle surrounding the moon phase.


The date ring matches the case on the red gold version of this Jaquet Droz Grande Seconde Moon.

Three different styles are available, with some subtle variations here and there. The first one is available with an 18-karat red gold case and a beautiful double level ivory Grand Feu enamel dial. The date ring, the stars and the 22-karat red gold moon match the case. The second model is pretty similar but the materials change. It features a stainless steel case, a silver opaline dial as well as star and moon appliques in 18-karat white gold and 22-karat white gold respectively. Finally, the third model varies a little bit colour-wise and some parts are changed. It features a fully black onyx dial and moon disc, and gets rid of the roman numerals as well as the seconds markers, making it look a bit sleeker and more modern.

One classic watch, three versions, three styles

Be advised that the case is rather large with a 43 mm diameter needed to house the Grande Seconde mechanism as well as the new moon phase. The complication is said to be astronomical, meaning it requires adjustment only once every 122 years and 46 days, thanks to its self-winding Jaquet Droz 2660QL3 mechanical movement. It features the specially developed “mechanism 135”, a 135-tooth gear, much more precise than a traditional 59-tooth model. The caliber also provides a nice 68 hours power reserve. Find out more about this Grande Seconde Moon here.
