About the Hublot Big Bang Unico Green Saxem
The Hublot Big Bang Unico line is built around the manufacture's UNICO flyback chronograph movement, an integrated, column-wheel caliber developed entirely in-house that cemented Hublot's credibility as a true manufacture. The Big Bang family itself launched in 2005 and became one of the defining sport-luxury watch designs of the 21st century, recognizable by its multi-layered bezel construction, exposed screws, and bold porthole-style case. The Green Saxem variant pushes that identity further by replacing conventional metal or carbon with Saxem, a material so difficult to produce that each case requires an extraordinarily complex manufacturing process, making these pieces as technically impressive as they are visually arresting. At 42mm the case sits at the sweet spot of the Big Bang range, wearable enough for daily use yet substantial enough to showcase the skeletonized dial and the movement architecture visible beneath it.
What to Look For
When shopping for a Hublot Big Bang Unico Green Saxem 441.JG.4990.RT, condition and completeness are paramount — confirm that the piece includes its original box, papers, and warranty card, as full-set examples command a meaningful premium over watch-only listings. Because Saxem is a highly specialized material, buyers should verify authenticity through a trusted independent specialist like Bizak and Co. rather than relying on surface appearance alone, since the vivid green hue and translucency of genuine Saxem are difficult to replicate but easy to misrepresent in photography.
Frequently Asked Questions
What is Saxem and why does it matter on the Hublot Big Bang Unico Green?
Saxem stands for Sapphire Ceramic Extreme Material, a proprietary composite developed by Hublot that merges the hardness and scratch resistance of sapphire crystal with the structural properties of ceramic. The result is a colored, semi-transparent case material that is far more durable than standard ceramic and gives the Big Bang Unico Green its distinctive luminous green appearance that no conventional material can replicate.
Is the Hublot Big Bang Unico Green Saxem 441.JG.4990.RT a limited edition?
Hublot has historically produced Saxem references in highly controlled quantities given the extreme complexity of manufacturing the material, making availability genuinely limited even when pieces are not formally numbered editions. If you are looking to buy the 441.JG.4990.RT, acting promptly is advisable as supply is constrained and secondary market premiums can apply when boutique stock is exhausted.
What movement powers the Hublot Big Bang Unico Green and can I see it through the dial?
The Big Bang Unico is powered by Hublot's in-house UNICO integrated flyback chronograph movement, which is visible through the skeletonized dial design that is a hallmark of the Unico line. The open-worked architecture lets you observe the column wheel, lateral clutch, and other movement components directly, making the watch a showcase of mechanical craft as much as a timekeeping instrument.
