The 'Purity' Tourbillon by ArtyA: a seamless blend of transparency and technology. It showcases an impressive tourbillon (at 18 mm in diameter, instantly recognizable as the movement’s signature) that is fully integrated as a distinctive design element. This feature highlights two key strengths of the ArtyA brand: the mastery of sapphire and the imagination in creating original horological movements. Equipped with two parallel-mounted barrels for powering the tourbillon beating at 4 Hz beating, the movement was, from its inception, conceived as a miniature exoskeletal sculpture. Weighing a mere 9 grams, it pushes boundaries through the use of cutting-edge precision and design technologies, while remaining true to meticulous traditional finishing, such as cast-iron sandblasting and hand beveling.
