2. Jaquet Droz Astrale Perpetual Calendar
Next on the list, and on the number two position we have the Jaquet Droz Astrale Perpetual Calendar watch.
Which comes in a 44mm in diameter and 13.53mm thick polished black ceramic case, and features a black “opaline” main dial plate.
On the dial we can spot the fine white printed index hour markers, with applied blackened white gold ring, secured to the dial with blackened steel screws.
The perpetual calendar automatically calculates the day, date, month, year correctly, including only 28 days in February on a leap year.
The Jaquet Droz Astrale Perpetual Calendar watch features a Jaquet Droz Caliber 5863 movement, contains 38 jewels and has an approximate power reserve of 68 hours.
