The Architecture of Precision
Val-de-Travers & Le Brassus Workshops
A homage to 18th-century observatory chronometers. The Aethelgard features an ultra-refined cream opaline dial layered with grand feu enameling and blued steel Breguet-style hands. The solid Platinum 950 case evokes classical proportion, housing one of the thinnest automatic perpetual calendar movements ever conceived in contemporary horology.
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.”
Other Exemplars in the Collection
Nocturne Flying Tourbillon
A transcendent study in high-contrast horology. The Nocturne Flying Tourbillon suspends time in zero gravity with a 60-second tourbillon carriage floating above a ruthenium-plated dial with hand-chamfered bridges.
Monochrome Openworked Calibre
Every superfluous milligram of metal has been carved away by hand. The Monochrome Openworked reveals the beating heart of high-speed balance oscillations through sapphire crystals on both faces.
