Source your dream watch

The Hublot Big Bang Unico Green Saxem 441.JG.4990.RT is one of the most visually arresting references in Hublot's celebrated Big Bang lineup, combining the brand's signature fusion philosophy with a case crafted entirely from Saxem — a proprietary synthetic mineral compound that Hublot developed to achieve extraordinary chromatic intensity and near-diamond hardness. First introduced to widespread acclaim, the Big Bang Unico family redefined what a luxury sports chronograph could look and feel like, and the green Saxem variant sits at the very pinnacle of that vision. Owning this reference means wearing a piece of horological material science on the wrist.

At 42mm, the Big Bang Unico Green Saxem occupies a sweet spot in the Hublot catalog: large enough to command immediate wrist presence and project confidence, yet measured enough to suit a wider range of wrist sizes than the flagship 45mm case. The 42mm diameter has become the preferred choice for collectors who want the full visual drama of the Big Bang architecture — the exposed construction screws, the open-worked aesthetic cues, the multi-layered case profile — without sacrificing comfort during extended wear. Reference 441.JG.4990.RT delivers all of that in an eye-catching green that shifts in tone depending on the light source, from a deep forest hue indoors to a luminous jade brilliance in natural sunlight.

The dial of the 441.JG.4990.RT is finished in black and populated with a combination of index and Arabic numeral hour markers, a layout that balances legibility with the sporty character the Big Bang Unico is known for. The contrast between the black dial and the vivid green Saxem case and bezel creates a depth of field effect that draws the eye inward, making the watch feel architecturally three-dimensional even at rest. Every surface detail — from the applied markers to the integrated chronograph subdials — reflects Hublot's commitment to high-contrast, instantly readable dial design.

Powering the Big Bang Unico is an automatic movement that drives the in-house UNICO chronograph module, the architecture at the heart of this entire model family. The UNICO column-wheel flyback chronograph mechanism is a hallmark of serious watchmaking ambition from Hublot, demonstrating that the brand's technical credentials match its design boldness. The movement is visible through the sapphire exhibition caseback, a design choice that rewards curious collectors with a direct view of the mechanical beating heart beneath the striking exterior.

Bizak & Co. is proud to offer this reference 441.JG.4990.RT in brand-new condition, complete with box and papers — the full package that protects your investment and confirms authenticity. Buying new ensures you receive the full manufacturer warranty, an unblemished case and bracelet, and the confidence of provenance that discerning collectors demand. The green Saxem Big Bang Unico is not a watch produced in large volumes; it is a statement piece for the collector who refuses to compromise on originality.

1. What makes the Hublot Big Bang Unico Green Saxem 441.JG.4990.RT special?
The 441.JG.4990.RT is distinguished by its case and bezel crafted from Saxem, Hublot's proprietary synthetic mineral that delivers exceptional scratch resistance and a vivid, translucent green color impossible to replicate in conventional metals or ceramics. Combined with the in-house UNICO automatic chronograph movement and the iconic Big Bang architecture, this reference represents the pinnacle of Hublot's fusion philosophy. It is a rare and visually unmistakable collector's piece.

2. What movement powers the Hublot Big Bang Unico 441.JG.4990.RT?
The 441.JG.4990.RT is driven by an automatic movement featuring Hublot's proprietary UNICO in-house chronograph module, a column-wheel flyback mechanism that showcases the brand's serious technical ambitions alongside its bold design. The movement is visible through the sapphire exhibition caseback, offering an engaging view of the mechanical assembly. As with all UNICO references, the movement is developed and produced by Hublot's manufacture.

3. What is the case size of the Hublot Big Bang Unico Green Saxem?
The Big Bang Unico Green Saxem 441.JG.4990.RT measures 42mm in diameter, placing it in the mid-size tier of the Big Bang Unico family. This size delivers commanding wrist presence and the full visual drama of the Big Bang case architecture while remaining wearable across a broader range of wrist sizes than the larger 45mm variants. It is an ideal choice for collectors who want impact without excess bulk.

4. Is the Hublot Big Bang Unico Green Saxem suitable for everyday wear?
The Saxem material used in the 441.JG.4990.RT is extremely hard and highly resistant to scratching, making the case and bezel far more durable in daily use than standard metal or ceramic alternatives. The rubber bracelet further supports an active lifestyle, providing comfort and resilience across varied conditions. While it is undeniably a luxury statement piece, its materials engineering makes it genuinely suited to regular wear.

5. What is Saxem and how does it affect the dial and case of the 441.JG.4990.RT?
Saxem is a proprietary synthetic mineral compound developed by Hublot that combines the optical clarity and hardness of sapphire crystal with the ability to be produced in vivid, saturated colors — in this case a distinctive green. The material gives the 441.JG.4990.RT its translucent chromatic depth, with the green shifting in tone from deep forest to luminous jade depending on the light. The black dial inside the Saxem case creates a striking high-contrast visual effect that makes the watch immediately recognizable.
