By Hublot
The Hublot Big Bang Unico 421.MX.1130.RX is a brand-new 44mm automatic chronograph crafted entirely in Hublot's proprietary Magic Gold — a scratch-resistant 18k gold alloy — and finished with a striking black skeleton dial and matching black rubber strap. This reference pairs the bold, architectural proportions of the Big Bang family with the unmistakable warmth and exclusivity of Magic Gold, making it one of the most distinctive luxury sport watches available today.
What sets the 421.MX.1130.RX apart is the rare combination of a near-indestructible gold case material and an open-worked dial that showcases the in-house Unico movement beneath — a pairing few watches at any price point can claim. Available brand new with full box and papers, this is an exceptional opportunity for collectors and enthusiasts alike; contact Bizak & Co. today to secure yours at the best price.
