A limited edition of just 30 pieces is the Frederique Constant watch dedicated to the most demanding enthusiasts: the Highlife Perpetual Calendar Manufacture in 18-carat rose gold. The 41 millimetre case, redesigned from the first model in the collection presented in 1999, houses a dark blue dial decorated with a globe-shaped motif, with luminescent rose gold-plated indexes and hands and with month, leap year, day and date counters with a sunray finish. To maintain the purity of the case design, all the perpetual calendar correctors have been integrated, leaving room for a single pink gold crown at 3 o'clock. The integrated strap is made of alligator with a blue Nubuck finish, exclusive to this model, and is equipped with a system that makes it interchangeable without the need for special tools. The watch is powered by the FC-775 manufacture calibre, mechanical with automatic winding, 28,800 vibrations per hour, 38-hour power reserve and details such as perlage and côtes de Genève finishing visible through the sapphire crystal case back. It is on sale for €29,995.
