The red needle for seconds, underlines the Motorsport appeal. Superluminova technology for the hour and minute hands. The screw-on back makes the watch water resistant to 10 ATM. It is secured on your wrist by a superbly designed solid stainless steel bracelet that follows the lines of the case and closes with a double safety clasp which has a hidden extension, just in case you have a thick wrist (a rare feature).
