Jaquet Droz Introduces New Grande Seconde Moon in Black Enamel (Updated with Price)

Jaquet Droz added a moon-phase complication to its growing collection of Grande Seconde timepieces at last year’s Baselworld. At Baselworld 2018, Jaquet Droz offers up the latest version of the Grand Seconde Moon, now fronted by a handsome black enamel dial.

Like its predecessors, the Jaquet Droz Grande Seconde Moon Black Enamel features on its double-level grand feu enamel dial an astronomical moon-phase indicator that requires adjustment only once every 122 years and 46 days. Jaquet Droz’s specially developed “mechanism 135,” which drives the moon-phase indication, has a carefully studied gear ratio that makes it much more precise than the 59-toothed mechanism in a traditional moon-phase, which accumulates an error of one day in approximately two years, seven months, and 20 days.

The moon-phase disk, centered inside a satin-finished gold ring for the date display and a 60-second scale for the running seconds, is made of black onyx, with tiny gold stars and a realistic-looking moon made of 18k rose gold that rotates clockwise in synch with the actual moon’s lunar cycles. The double-level structure of the dial aids in legibility, while a corrector positioned in the side of the case at 8 o’clock — operated by a stylus that is included with each watch — makes adjustments of the moon-phase easy. The upper subdial, the other element of the Swiss brand’s hallmark figure eight dial, displays the hours and minutes with gold hands on Roman numerals.

Inside the watch’s 18k rose gold case, measuring 43 mm in diameter, is a self-winding movement, Caliber 266QL03, with 30 jewels, 68 hours of power reserve stored in a double mainspring barrel, a balance spring and pallet horns made of friction-resistant silicon, and a solid gold oscillating weight — all in plain view behind a sapphire caseback. The watch comes on a rolled-edge hand-stitched black alligator strap with an ardillon buckle made of 18k rose gold.  The price is $28,900.
