This replica spirit big bang 7180 42mm uses reference 642.OX.7180.RX to pair a blue sunburst dial with a full King Gold tonneau case, combining two of the most visually active elements in Hublot’s Spirit catalog into a single reference. King Gold’s warm rose tone against a cool blue dial generates a color tension that shifts continuously under changing light. At 42mm across the barrel profile, the precious-metal case adds tangible weight to the wrist, and the angular surfaces of the tonneau shape amplify the polished gold reflections compared to round alternatives.

Technical Overview

• Case material: King Gold (proprietary rose gold alloy)
• Case dimensions: 42mm barrel-shaped
• Dial: blue sunburst 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 blue rubber strap picks up the dial color and creates a chromatic loop from case top to wrist bottom. The six titanium bezel screws provide a deliberate material break against the polished gold, reinforcing the industrial design vocabulary that separates Spirit from conventional gold dress watches.

Inside the Movement

An automatic caliber handles hours, minutes, seconds, and date, with a gold-finished rotor visible through the sapphire caseback. The blue dial’s sunburst pattern stretches across the tonneau shape’s longer diagonal planes, creating a sweep of color that round watches cannot produce at the same scale. The blue titanium 642.NX.7170.RX offers the same dial color in a lighter, more understated case for buyers who prefer titanium over gold. Both references represent the blue side of the Spirit of Big Bang collection.

What Sets It Apart

Blue dials in gold cases have become a proven combination across luxury watchmaking, but the tonneau form gives this pairing a geometric edge. The angular planes refract both the gold case reflections and the blue sunburst pattern differently than curved surfaces would, which keeps the watch visually dynamic even in static positions. The 642.OX.7180.RX targets buyers who want the warmth and presence of King Gold alongside a dial color that keeps the piece from reading too traditional. This replica spirit big bang 7180 42mm puts the tonneau’s boldest color-meets-metal formula on the wrist.
