This replica spirit big bang 7180 blue pairs a King Gold case with a deep blue dial on reference 642.OL.7180.RX, creating one of the most visually rich entries in Hublot’s Spirit of Big Bang catalog. King Gold is the brand’s proprietary alloy blending pure gold with platinum and copper for a redder, more resilient tone than standard rose gold. At 42mm across the tonneau profile, the warm case metal against the cool blue dial produces a contrast that shifts noticeably between indoor and outdoor lighting.

Case & Movement Specs

• Case material: King Gold (proprietary rose gold alloy)
• Case dimensions: 42mm barrel-shaped
• Dial: sunburst blue with applied gold indices
• Crystal: sapphire with anti-reflective coating
• Bezel: polished King Gold with six H-shaped titanium screws
• Strap: blue structured rubber
• Movement: automatic

The six exposed screws on the bezel are a Spirit of Big Bang signature. On the King Gold version they sit in titanium to create a deliberate material contrast against the polished gold surface. The blue rubber strap picks up the dial color and wraps the warm-cool theme all the way around the wrist.

Caliber Breakdown

Inside, an automatic movement handles hours, minutes, seconds, and date. The gold rotor visible through the sapphire caseback complements the case metal, maintaining material consistency from every viewing angle. Compared to the yellow ceramic 642.CY.011Y.RX, which takes a monochrome ceramic approach, this King Gold reference trades boldness for luxury finishing.

How It Compares

King Gold references occupy the top tier of the Spirit lineup, and the blue dial choice keeps the piece from reading too formal or too conservative. The warm gold tones against a cold blue surface create enough visual tension to hold attention without relying on skeleton dials or complicated bezels. On the wrist, the 642.OL.7180.RX carries more heft than the titanium alternatives, which reinforces the precious-metal impression through feel alone. This replica spirit big bang 7180 blue delivers a tonneau dress-sport watch that prioritizes material richness over mechanical spectacle.
