The black PVD finishing offers a technical and intense fresh look. The PVD treatment (Physical Vapor Deposition) is a metallisation process that allows to vacuum deposition of material thin films thanks to the steam. This surface treatment has first of all an aesthetical interest. It offers new shades always in favour of the watch’s mechanism. The PVD give a superior strength. The use of this process characterise three of the RESERVOIR’s models: the GT Tour 371 SE in edition limited, the Airfight Jet and the Airfight Propeller.
