Patravi ScubaTec Black | Carl F. Bucherer

This Patravi ScubaTec Black's connection to the ocean goes far beyond its appearance. With its screw-down crown and automatic helium release valve, it is ideal for underwater adventures – as evidenced by its water-resistance to 50 bar (500 m). It is reliably powered by the CFB 1950.1 caliber automatic movement with a power reserve of 38 hours. Its extraordinary precision has been officially confirmed by the Contrôle Officiel Suisse des Chronomètres (COSC) independent Swiss chronometer testing institute. Each watch is accompanied by an individual COSC certificate.
