The Magic of Gold & Titanium
Titanium was born for orbit, engineered for pressure, heat, and silence. Gold came the other way: ancient matter, a fading echo of supernovae, delivered to Earth long before memory itself. One metal reaches outward toward the future, the other carries the weight of time, as precious and scarce as our finest memories. The Leger Openwork timepiece is an artistic fusion of what humanity sends into space and what space once entrusted to Earth.
Leger Openwork distills everything Saint Bones stands for: ornamental, off-beat design, signature pattern inspired by French Gothic tracery, and an avant-garde approach to form where material is both structure and expression. Openwork tracery defines the case crafted in 18k gold, allowing light and depth to expose the foundation executed in grade 5 titanium.
High-end Swiss Automatic Movement
The heart of every Saint Bones timepiece is an exceptional automatic Swiss movement: the Caliber SW300-1, produced by Sellita SA. Top of the line and among the thinnest movements on the market, it is both regulated and decorated to the highest standards.

Ultra-small Series Production
We conceive, design, engineer, and craft the Leger Openwork timepieces in our workshop in Vienna, Austria. Each piece is made individually as part of an ultra-small series. True to the philosophy of Saint Bones, every watch is produced to order, never in volume. Limited by intent rather than by number, Leger Openwork exists as a personal object defined by precision, restraint, and rarity.
