The Art of Guilloché
The SB04-E “Exquisite Blue Guilloché” celebrates the enduring beauty of hand-crafted guilloché work.
A luminous outer ring reveals a flowing blue gradient — shifting from a deep, moody tone to a soft, airy shade — each line engraved to catch and scatter light with the slightest motion of the wrist.
At the center, a pristine white guilloché surface offers a serene, radiant backdrop, enhancing the play of depth, texture, and color.
Precision in Design
Hovering above this sculpted landscape is the model’s signature sapphire ring — thin, clear, and anti-reflective — carrying its indexes in a way that leaves the guilloché fully visible beneath.
Alternating markers shimmer with polished, diamond-cut facets, while the others are pad-printed using Sartory-Billard’s distinctive Y-pattern.
This layered construction creates a sense of depth, as though the guilloché is suspended beneath the surface, alive with motion, light, and shadow.
Hands That Illuminate
Each hand is shaped from metal with crisp, precise cuts and refined by hand.
The hour and minute hands feature a brushed finish and luminous material that emits a turquoise glow in darkness.
The sweeping seconds hand moves with effortless balance, tracing a quiet path above the engraved dial.
Time becomes a living sculpture — shifting, shimmering, and revealing new nuances as the day unfolds.
Heritage in Motion
This creation continues Sartory-Billard’s dedication to merging aesthetic purity with mechanical integrity.
Every detail — from the engraved caseback to the carefully proportioned screw-down crown — reflects intention and refinement.
The SB04-E achieves a harmony of elegance and resilience, ensuring that each element contributes both beauty and performance.
The Legacy of Guilloché
For centuries, guilloché has embodied the meeting point of artistic expression and mathematical precision in watchmaking.
Born in Europe during the age of classical craft, this engraving technique once adorned royal objects and fine jewelry before becoming integral to haute horlogerie.
At Sartory-Billard, this heritage is not merely preserved — it is re-imagined.
In the Saint-Croix workshop, traditional motifs are recreated through modern CNC engraving, transforming metal into a dynamic texture of light and movement.
A refined color gradient, crafted in Geneva, adds a contemporary layer to this timeless craft, and each watch is assembled by Armand in France, bringing the journey full circle.
The SB04-E “Exquisite Blue Guilloché” captures the union of past and present — where age-old artistry meets modern execution, and color becomes the bridge between tradition, innovation, and emotion.
Conforming to Your Wrist
With its ergonomic lugs and graceful proportions, the SB04-E settles naturally against the wrist.
Each piece arrives with a smooth white rubber strap and a metal bracelet, both featuring quick-release systems for seamless changes.
Comfortable, expressive, and refined, it is crafted not only to be worn — but to be truly experienced.
