The Sartory-Billard SB04-E Aventurine Starry Night elevates contemporary independent watchmaking with a dial carved from a single block of deep midnight-blue aventurine. Its natural metallic inclusions create a shimmering, stardust-like effect that shifts with every movement, giving the watch an unmistakably celestial presence. Each dial is inherently unique due to the mineral’s natural formation, making every SB04-E a singular piece of horological art. Above this cosmic backdrop floats the brand’s signature ultra-thin sapphire disk, an architectural layer that carries the indexes while preserving the purity of the stone beneath. Diamond-cut markers, BGW9 Super-LumiNova accents, and the proprietary Y-shaped luminous layout enhance legibility while adding modern character. Sculpted hands, brushed, hand-finished, and luminous, glide over the aventurine like celestial bodies, with the polished seconds hand tracing a comet-like path across the night sky.
Ref. SB04E1DBAVEN
A blend of luxury craftsmanship and practical durability, the SB04-E features a concave bezel that draws light into the dial, a steel case alternating between polished and satin finishes, and balanced proportions that appear slimmer than its 10 mm height. The refined caseback now carries the fluting once reserved for the rotor, reinforcing the collection’s evolving design language, while the screw-down crown glows softly with BGW9 Super-LumiNova. With 100-meter water resistance, curved 20 mm drilled lugs, and an ergonomic rubber strap designed for everyday comfort, the SB04-E seamlessly marries elegance with performance. A stainless-steel bracelet is also available for collectors seeking an elevated, versatile look.
