Astronomic Blue

Constructed from more than 750 components ( which don’t include the tantalum case), F. P. Journe’s Astronomic Blue features 18 complications and functions, which can all be adjusted from a single crown. Its hand- wound, double- barrel 1619 calibre in rose gold can be seen through the caseback crystal, as can the date, annual- calendar and equation- of- time displays. On the front, the blue- chrome dial shows the following indications: hours, minutes and seconds of average time; second time zone; hours, minutes and seconds of sidereal time; sunrise and sunset; day and night; moon phases and power reserve. The tourbillon at 3.30 has a rémontoire d’égalité that completes a complete rotation in 60 seconds. This incredibly complex and beautiful watch also features a minute repeater. Estimate: US$ 300,000-$ 600,000 Actual: US$ 1.8 million
