Bell & Ross has released a full sapphire variant of the Cyber Skull fitted with a translucent strap which it calls the BR 01 Cyber Skull Sapphire.

The BR 01 Cyber Skull Sapphire has as its base a Cyber Skull, developed entirely in colourless sapphire crystal. The skull and crossbones are captured between two sapphire crystals, so that they appear to be floating in the air.

Inside, the BR-CAL.209 automaton movement has been specifically developed for the watch. This manual-wind skeleton calibre is almost invisible, taking the form of the aforementioned skull. The spring balance placed at “twelve o’clock” symbolises the brain in this skull which is very much alive.
