Since its debut at Baselworld in 2005, The Hublot Big Bang collection has established itself as a new icon of modern luxury sports watches. The collection is notable for its bold style that breaks the mold of traditional watch design and its combination of innovative materials, And is the representative line that best represents Hublot’s “Art of Fusion” philosophy.
The Hublot Big Bang Unico King Gold 441.OX.1181.RX is a flagship chronograph with a 42 mm 18K King Gold case and bezel, And a matte black skeleton dial. King Gold is Hublot’s exclusive alloy that has a warmer and deeper glow than traditional 5N red gold, And combines satin and polished finishes. The dial highlights the complex mechanism of the double coupling system and column wheel, Emphasizing a three-dimensional and dynamic feel.
The movement is the in-house automatic chronograph caliber HUB1280 Unico, Featuring a flyback function, Column wheel, 72-hour power reserve, And 100m water resistance. The sapphire crystal and transparent case back enhance durability and perfection, And the black rubber strap and King Gold clasp provide a luxurious finish.
This model is a timepiece that represents Hublot's innovative fusion of materials and mechanical aesthetics. The three-dimensional effect of the skeleton dial and the warmth of King Gold combine to deliver a splendid yet unique sensibility.
