For its tenth collaboration with L'Epée 1839, Switzerland's premier clockmaker, MB&F dove to the bottom of the sea, where the jellyfish are, and returned with Medusa; a clock housed inside an artisanal, mouth-blown Murano glass dome. It is designed to stand on a desk or to hang from the ceiling, in which case trailing Murano glass tentacles can be added. Two rings rotate under a fixed indicator to show hours and minutes through the dome. Like the creature that inspired it, Medusa glows in the dark thanks to a coating of Super-LumiNova. This concept clock will be made as three limited editions of 50 pieces each, in blue, green or pink.
