The Hublot Big Bang Unico GMT 471.OX.7128.RX is among the most visually commanding expressions of Hublot's celebrated Big Bang family, combining the brand's hallmark Art of Fusion philosophy with a dual-timezone GMT complication housed in a 45mm King Gold case. King Gold is Hublot's proprietary 18-karat rose gold alloy, developed in-house to deliver greater scratch resistance and a richer, deeper color than standard gold — a material innovation that underlines the brand's commitment to technical and aesthetic excellence.

The dial of the 471.OX.7128.RX is a fully skeletonized construction, offering an unobstructed view into the movement's architecture while retaining legibility through a combination of index hour markers and bold Arabic numerals. This interplay of open-worked mechanics and purposeful typography gives the watch a dramatic, contemporary character that distinguishes it from more conventional dress pieces and appeals strongly to collectors who demand both artistry and function on the wrist.

Powering this reference is an automatic movement with GMT functionality, allowing the wearer to track a second time zone simultaneously — an invaluable complication for frequent travelers and global professionals. Hublot's Unico movements are designed and manufactured in-house, reflecting a true manufacture philosophy that elevates the brand beyond pure assembly and into genuine horological craftsmanship. The visible movement architecture through the skeleton dial rewards close inspection and reinforces the watch's value proposition.

At 45mm in King Gold, the Big Bang Unico GMT 471.OX.7128.RX commands immediate wrist presence. The King Gold case pairs with a matching King Gold bezel and is mounted on a supple rubber strap — a signature Hublot detail that balances the weight of the precious metal case with everyday wearability and a sporty, modern edge. The contrast between the warm gold tones and the black rubber strap is one of the most iconic visual signatures in contemporary watchmaking.

Bizak & Co. is pleased to offer this reference brand new, representing an outstanding opportunity to acquire one of Hublot's most prestigious Big Bang configurations. Whether you are a seasoned collector adding a statement GMT to your rotation or a first-time Hublot buyer seeking the definitive expression of the line, the 471.OX.7128.RX delivers on every front. Reach out to our team at bizakandco.com for pricing, availability, and personalized assistance — we are committed to making your purchase experience as exceptional as the timepiece itself.

1. What makes the Hublot Big Bang Unico GMT 471.OX.7128.RX special?
The 471.OX.7128.RX combines Hublot's proprietary King Gold alloy — an 18-karat rose gold developed for superior scratch resistance and deeper color — with a skeleton dial and a GMT complication, making it one of the most technically and aesthetically ambitious references in the Big Bang Unico line. The open-worked dial reveals the movement in dramatic fashion while index markers and Arabic numerals maintain readability. It is a true fusion of luxury material, in-house manufacture, and practical complication.

2. What movement powers the Hublot Big Bang Unico GMT 471.OX.7128.RX?
The watch is powered by an automatic movement with GMT functionality, allowing simultaneous tracking of a second time zone. Hublot's Unico movements are produced in-house, reflecting the brand's manufacture credentials and commitment to vertical integration. The skeleton dial affords a direct view of the movement's working components, adding visual depth to the technical story.

3. What is the case size of the Hublot Big Bang Unico GMT 471.OX.7128.RX?
The reference 471.OX.7128.RX features a 45mm case crafted entirely in King Gold, Hublot's proprietary 18-karat rose gold alloy. This generous diameter ensures strong wrist presence and is consistent with the bold, statement-oriented design language of the Big Bang Unico collection. The King Gold bezel completes the all-gold case aesthetic.

4. Is the Hublot Big Bang Unico GMT 471.OX.7128.RX suitable for everyday wear?
Despite its precious King Gold construction and 45mm footprint, the rubber strap makes the 471.OX.7128.RX surprisingly wearable day to day, cushioning the wrist and reducing the perceived weight of the case. King Gold's enhanced hardness compared to standard gold also improves resistance to everyday abrasion. It suits confident, style-conscious wearers who want a luxury statement piece that can transition from boardroom to leisure.

5. What does the dial look like on the Hublot Big Bang Unico GMT 471.OX.7128.RX?
The dial is fully skeletonized, meaning the traditional solid dial plate is removed to expose the movement's internal mechanics as a decorative and technical element. Hour markers are rendered as both indices and Arabic numerals, providing clear legibility against the complex visual backdrop of the open movement. The combination of warm King Gold tones and the architectural skeleton creates a rich, layered aesthetic that is unmistakably Hublot.
