Price range: $850.00 through $1,650.00
The Hublot Big Bang “All Black” 421.NX.1170.RX Replica is a bold and modern recreation of one of Hublot’s most iconic monochrome designs. Powered by either a Swiss or Japanese automatic mechanism, it delivers smooth sweep motion and reliable precision, with the Swiss caliber offering COSC-level performance for a truly authentic Hublot experience.
The 44 mm case features a full black titanium-style finish crafted on premium materials, reflecting the signature stealth aesthetic of the “All Black” concept. Sapphire crystal protection ensures durability and clarity, while the structured black rubber strap provides exceptional comfort, flexibility, and a secure fit for everyday wear.
Its clean black dial showcases luminous hour markers, polished hands, and a refined chronograph layout, maintaining excellent readability while preserving the bold, minimalist identity of the Big Bang collection. The all-black design creates a powerful and understated presence on the wrist.
As a super clone 1:1 edition, every detail—case structure, dial finishing, engraving precision, chronograph layout, and strap integration—has been meticulously replicated to match the genuine 421.NX.1170.RX with outstanding accuracy. Backed by a full 2-year International United Luxury warranty, this model delivers craftsmanship, performance, and the unmistakable modern edge of Hublot’s Big Bang line.
