Inside is the self-winding calibre 777 Q, offering 55 hours of power reserve. The dial is guilloché, worked with the engine-turning technique that gives the surface its structure and play of light. A date function and central seconds complete the display, and the sapphire case back reveals the movement's finishing. The watch is set with diamonds.
