Behold the pinnacle of true horological independence: our fully in-house developed tourbillon movement, engineered with unwavering precision and visionary craftsmanship.
At its core, a finely executed flying tourbillon rotates gracefully at the lower left. Its exposed cage and escapement create a mesmerizing display of mechanical poetry. With every silent revolution, it counteracts gravity’s effects, ensuring exceptional accuracy. Meanwhile, the intricate dance of wheels, bridges, and ruby jewels captivates the eye—all meticulously finished on brushed and polished plates.
Opposite the tourbillon, a dedicated small seconds subdial at 6 o’clock adds rhythmic elegance. Its delicate hand sweeps in perfect harmony with the beating balance. Consequently, the open architecture reveals every layer of complexity. Therefore, it celebrates transparency and the raw beauty of fine watchmaking.
Developed entirely in our atelier, this caliber represents years of dedicated research. We select high-grade materials and optimize gear trains for superior performance. In addition, hand-assembled components deliver outstanding stability, a smooth 28,800 vph beat rate, and reliable long-term precision.
Tailored for discerning brands seeking signature complications, we offer comprehensive customization. For instance, options include bridge engravings, bespoke finishing (perlage, Côtes de Genève, or blued screws), power reserve additions, or layout variations. As a result, all modifications are executed with factory-direct efficiency and uncompromising quality.
