The delicate and fragile nature of aventurine, contrasting with the hardness of glass, makes the machining and polishing processes very intricate. This material requires specialized and highly technical expertise to shape it into a dial for all assembly operations. The dial features appealing contrasts between mirror-polished aventurine, translucent sapphire, and metallization for improved readability. The transfers are applied by hand and the hour-markers are crafted from solid rose gold.
Over 32 hours, the bridges and plates of the Rolex calibre 4130 were entirely hand-cut using a small bocfil saw and decorated before being colored in anthracite tones known as Black Or. A special skeletonized rotor in rose gold was also added. The chronograph mechanism is revealed through the three counters at 3, 6, and 9 o’clock. The mirror-polished aventurine dial is enhanced by a satin-finished rose gold bezel, complemented by an aventurine insert.
The Artisans de Genève Ventura Daytona is a timepiece made of contrasts: the deep blue of aventurine meeting the warmth of rose gold, the mysterious transparency of glass, and the warm shimmer of copper as common threads.
