- Concentric guilloché on dual sub-dials: precision-machined texture for enhanced mechanical detail.
- Applied polished indices for clear readability.
- Enamel-printed markings, crisp and fade-resistant.

st1901 top grade
This movement showcases a level of artistry defined by finer, light-catching Côtes de Genève stripes that create a mesmerizing visual rhythm. It features a clean, sophisticated monotone finish, elevated by hand-polished bridges and components where every edge has been meticulously smoothed by master watchmakers. Striking hand-brushed accents provide a nuanced contrast against the pristine rhodium plating, ensuring superior corrosion resistance and a luxurious, signature silver-white glow.

Pure vintage precision, re-engineered
Engineering Heritage
Rooted in the legendary Swiss Venus 175 architecture, the ST1901 stays true to its heritage by preserving the traditional column-wheel mechanism for an authentic, crisp tactile experience. By blending this soulful mid-century design with modern precision, we have created a movement that offers both the nostalgic charm of a classic manual-wind chronograph and the reliability required for today’s wearer.
