The Moonray Tourbillon derives its name from the moonray pattern of the 48 blue sapphire baguettes (1,7 cts) on the movement baseplate, surrounding the hand guillochéd and hand enameled 'Star Night' dial fitted with 26 gold stars on a background of the deepest blue from the enameler's oven. The signature Delanneau tourbillon bridge and the strap with 18ct white gold deployant buckle are set with 24 and 96 diamonds respectively totaling 0,87 cts. To finish the whole ensemble, the case of the watch is decorated with 33 baguette shaped blue sapphires (5,38 carats) and 272 diamonds (2,23 carats) with 2 blue sapphire cabochons and a diamond in the crown.
