This past March, at Baselworld 2017, the Swiss watchmaker, Jaquet Droz, introduced the Grande Second Moon, which comes in stainless steel with a silvery dial, stainless steel with an onyx dial, and red gold with an ivory enamel dial.

The watch measures 43 mm in diameter and is powered by in-house Jaquet Droz caliber 2660QL3, which is a 30 jewel automatic movement with a 68-hour power reserve. It is equipped with a silicon balance spring and pallet horns, double barrel, and a skeletonized oscillating weight.

As is the signature of jacket Droz, the dial features off-center indications. Hour and minutes are displayed in the smaller subdial at 12 o’clock with printed Roman numeral hour markers (except on the onyx version). The larger subdial below has a running second display on the peripheral ring, with a date by hand just inside of that, and in the very center is a moon phase indicator, crafted in blued steel (which is black on the onyx dial version), with star and moon appliques in 18K white gold and 22K white gold respectively.

The push-in crown is signed with the Jaquet Droz stars logo. Water-resistance is 30 meters. The price is $15,200 in steel.
