Product Description
This Hublot Big Bang Steel Ceramic 301.SM.1770.RX Replica watch combines the bold proportions of the Big Bang collection with a classic contrast of stainless steel, black ceramic, and textured rubber. The substantial 44mm stainless steel case is framed by a black ceramic bezel secured with six signature H-shaped screws, emphasizing the industrial and technical character of the design. At the center, a black carbon-fiber-textured dial features a three-register chronograph layout, complemented by luminous baton hour markers and hands for a strong, highly recognizable sporting appearance.
Produced by HBF and powered by a 4100 automatic chronograph movement, this automatic replica watch is protected by sapphire crystal and paired with a structured black rubber strap with a folding clasp. The combination of brushed steel surfaces, a dark ceramic bezel, carbon-fiber-style dial texture, and black rubber gives the watch a robust and cohesive character. Its 44mm dimensions and traditional three-register chronograph display create a substantial wrist presence while maintaining the classic performance-inspired identity associated with the Big Bang Steel Ceramic design.
