The Architecture of Precision
Val-de-Travers & Le Brassus Workshops
A radical sculpture in light and space. Titanium bridges treated with dark charcoal galvanic bath create dramatic geometric shadows across the gear train. The open barrel allows the wearer to witness the tension of the mainspring directly, serving as an intuitive and poetic power indicator.
Every individual exemplar is submitted to a grueling 21-day chronological testing regimen across six positions and three temperature variations before receiving the chronometer certificate.
“We do not merely assemble gears; we sculpt friction into timeless harmony.”

Aethelgard Quantième Perpétuel
A secular perpetual calendar programmed to track leap years, months, dates, and astronomical moon phases until the year 2100 without manual intervention.
