The Chronomètre Furtif combines a tungsten-carbide case and bracelet with tantalum components. Its 42 mm case houses the manually wound, rose-gold calibre 1522, with central hours, minutes and seconds. The anthracite Grand Feu enamel dial uses frosted numerals whose visibility changes with the angle of light. Turn the watch over and the moon phase and power-reserve indications become visible. This is a model guide, not a claim of a new October release; availability and transaction prices require separate confirmation.
