To support the Only Watch 2023 charity auction, independent luxury watchmaker F.P.Journe presents a unique model designed exclusively for the occasion, the Chronomètre Furtif Bleu.
Made especially for Only Watch 2023, this one-of-a-kind timepiece features a tantalum case and bracelet, with an 18K rose Gold movement.
The Chronomètre Furtif takes its name from the difficulty of reading the time if the watch is not facing you, as the blue enamel dial reveals the frosted numerals only in the reflection of light. In addition, the moon phase and power reserve indications are integrated into the movement and visible only on the back.
At the heart of this watch is a new hand-wound mechanical movement, Calibre 1522 in 18K rose Gold with direct central seconds, a first for F.P.Journe.
