Royal Blue Tourbillon
This Masterpiece completes the Royal Blue Tourbillon collection from Ulysse Nardin. A highly-skilled precious stone cutter must cut each diamond and sapphire to perfection to fit the elaborate platinum case. The case of a diameter of 43 mm, especially created for this exceptional timepiece, is set with 128 baguette diamonds and 57 blue sapphire baguettes which enhance the rounded shape of the case. The actual setting of the bracelet of 432 baguette diamonds (approx. 27.77 ct) and 176 blue sapphire baguettes ornament the complexity of the bracelet construction. The crown fitted with 8 baguette diamonds and 1 cabochon sapphire further emphasizes the delicacy of this true jewel. A total of 568 baguette diamonds of the highest quality (approx. 33.8 ct, Top Wesselton) and 234 baguette cut royal blue sapphires (approx. 16.79 ct) in combination with the high art of watchmaking represent a delight for connoisseurs of fine timepieces.
Bridges and main plates are crafted in blue sapphire, making the flying Tourbillon itself float in an empty space. The movement parts are skeletonized and aligned in perfect symmetry. The winding system is invisible, further adding to the mystery. Despite the total transparency of this extraordinary movement (constructed along the principles of Le Locle’s most famous watchmaker - James Pellaton) one wonders what holds the flying tourbillon, which is revolving weightlessly in its cage.The interior of the platinum bezel is set with diamonds and blue sapphires to read the time. When winding the movement a miraculous force is setting cogs and wheels in different places in motion, completing the mystery of the Royal Blue.
