CHRONO II INVADERS PIRATES LIMITED EDITION 10 PIECES. The Challenge Chrono II Inkvaders Pirate by Cvstos, available in a limited series of about ten pieces each, celebrates the partnership between the Swiss luxury watch brand and the famous tattoo artist and designer Christian Nguyen, founder of the studio ‘Inkvaders’ in Geneva. These Pirate editions are distinguished by the colors and details of the hand-finished dial in order to give an aged patina to the Pirate’s skull. This wonderful painting is mounted on the Cvstos Chronograph which gives these pieces astrong and original identity.
