F.P.Journe Chronometre A Resonance with Analog 24 Hour Display

For the 20th Anniversary of the Chronomètre à Résonance, F.P.Journe proposes a version with a special dial that will be produced only during the year 2019. The hour dial at 3h maintain an analog 12 hour indication while the dial at 9h features for this edition an analog 24 hour indication.

The subtle 18K rose Gold mechanism with its two perfectly synchronized beating mechanical hearts for an unequaled precision in a wristwatch are visible through a sapphire crystal caseback.

The 2019 edition of the Chronomètre à Résonance is available in two versions: one with a Platinum case and white Gold dial, the other entirely in 18K 6N Gold.

The two dials in Silver guilloche Clous de Paris indicating the hours and minutes can also be set on two different time zones.
