For over two centuries, guilloché has represented the perfect harmony between art and mathematics in watchmaking.
Born in 18th-century Europe, this engraving technique was once reserved for royal objects and fine jewelry before finding its ultimate expression in watchmaking.
At Sartory-Billard, this heritage is not simply preserved — it is reimagined. In our Saint-Croix workshop, traditional motifs are brought to life through modern CNC engraving, transforming metal into a living texture of light and motion. The color gradient, crafted in Geneva, adds a contemporary dimension to this timeless artistry, while each watch is finally assembled by Armand in France.
The SB04-E “Exquisite Blue Guilloché” embodies this union of past and present — where ancestral craftsmanship meets modern execution, and color becomes the bridge between tradition, innovation, and emotion.
