Ref. 451.EX.5120.EX · Limited Edition 1 of 250
Presenting the Hublot Big Bang Integral Sky Blue Ceramic, reference 451.EX.5120.EX, a limited edition of only 250 pieces worldwide. The 42mm case, bezel, and fully integrated bracelet are crafted entirely from sky blue ceramic in a combination of satin-finished and polished surfaces, giving the watch its unmistakable monochrome presence on the wrist. Ceramic is highly scratch resistant and holds its color, so this piece keeps its look for years to come.
The matte sky blue skeleton dial opens up a full view of the in-house HUB1280 Unico caliber, a self-winding column wheel chronograph with flyback function and approximately 72 hours of power reserve. The bezel is secured by six signature H-shaped titanium screws, and the bracelet closes with a titanium deployant buckle. Water resistant to 100 meters, with a sapphire crystal and a display caseback.
