Prototype: F.P. Journe Astronomic Blue
This is one of those exceedingly rare moments in haute horlogerie—a prototype that has taken 14 years to develop is now up for sale. For collectors and connoisseurs alike, it’s not just a timepiece; it’s a statement investment in the upper echelons of elite watchmaking.
The F.P. Journe Astronomic Blue boasts a staggering 18 functions and complications, offering a fully mechanical astronomical display of every observable event from Earth. The full technical list is almost too extensive to detail, but key highlights include a tourbillon, leap year and temperature compensation, moonrise and moonset times, sunrise and sunset tracking, dual mainsprings, a second time zone, and a power reserve indicator.
All functions are intuitively controlled via a single crown, which also serves to manually wind the mainsprings. The case is crafted from tantalum—a rare and significantly more costly material than titanium, enhancing both its exclusivity and aesthetic appeal.
Price: $600,000
