de GRISOGONO's Tondo by Night watches made a dramatic entrance into the world of horology last year, and building on their unprecedented success, the brand has launched a new array of colour-popping shades for 2013. The latest blue, red and green models are as bold and colourful as de GRISOGONO's jewels. The Tondo by Night in blue not only looks bright - it shines bright too. The case is made from pearly photoluminescent composite fibreglass, which soaks up the sun by day and glows a fiery blue by night. Set with 108 electric blue sapphires on the bezel and face, chosen to match the exact shade of the case, it's the ultimate day-to-night accessory.
