Early F. P. Journe timepieces were fitted with brass movements and these are extremely collectible today. Journe timepieces maybe synonymous with 18k gold movements now but the watchmaker only started crafting his movements in gold from 2004. The early production models, between 2001 and 2004, featured brass movements – an estimated number of around 2,000. As a result Journe wristwatches with brass movements are rare and signify an epoch in the celebrated indie watchmaker’s sterling career. Launched in the year 2000, the Chronomètre à Résonance was a landmark wristwatch and notably featured two balance wheels that oscillate in resonance with each other.
