F.P.Journe Chronomètre Optimum for Prince Albert II of Monaco Foundation

Singapore, October 28, 2022 - The Prince Albert II of Monaco Foundation organized the 8th edition of the "Ball in Monaco" at the prestigious Marina Bay Sands in Singapore, in the presence of H.S.H. the Sovereign Prince and Mr. Vivian Balakrishnan, Singaporean Minister of Foreign Affairs.

Over the past 14 years, the Singapore branch of the Foundation has raised funds to finance more than two dozen projects for the protection of the planet. At the previous edition in 2018, the auction of a unique version of the Chronographe Monopoussoir Rattrapante raised SG$ 400’000. This year, F.P.Journe has donated a unique piece specially made for the occasion, a Chronomètre Optimum with a burgundy color and ruthenium-plated guilloché Silver dial and Chinese numerals. This model has the serial number 508-CO as well as a bespoke engraving on the movement, “S.A.S Albert II 2022 Singapore”.

The bidding for this Chronomètre Optimum started at SG$ 172’600. After a fierce battle between several collectors, it was finally sold for SG$ 1’480'000. The funds collected will be used by the Foundation to support concrete actions in Asia for the protection of the Ocean, the main theme of this "Ball in Monaco".

In an ongoing quest for precision, innovation and excellence, the Chronomètre Optimum symbolizes the very essence of François-Paul Journe's chronometric research for a wristwatch. At 11 o'clock, the wheel of the Remontoir d’égalité can be seen through an opening that invites you to discover the heart of the watch. On the back, the 18K rose gold movement reveals a natural deadbeat second delineated by a seconds circle screwed onto the bridges. This Calibre 1510 also benefits from two barrels and a High-Performance Bi-axial Escapement (EBHP), a patented F.P.Journe invention.
