The DiaStar Original Skeleton features the R808 automatic calibre with an anthracite-grey finish, showcased through sapphire crystal windows on both sides. It offers an 80-hour power reserve and uses an anti-magnetic Nivachron™ hairspring for precision. The open structure and R808 skeleton movement create a light feel, contrasted by a polished yellow gold Ceramos™ bezel. Floating yellow gold indexes and hands with white Super-LumiNova® enhance readability in low light.
