A natural evolution of the Square Bang collection
Launched in 2022, the Square Bang collection quickly stood out in Hublot's universe. With its 42 mm square case, it broke away from traditional round shapes to propose a bold design language. This new version, equipped for the first time with a tourbillon movement, marks a significant step in the line’s evolution.
A square case for a circular heartbeat
The Square Bang Tourbillon 4-Day Power Reserve features a unique architecture. Its MHUB6023 manual-winding movement has been developed in-house and tailored to suit the square format. All bridges are straight-edged, forming a fully orthogonal structure, and the skeleton construction enhances depth and transparency.

The movement is arranged for visual balance: the barrel at the top, the tourbillon at the bottom, the power reserve on the left, and the crown on the right. This layout reinforces the sense of harmony and mechanical logic that defines the piece.

The strength of 3D carbon
The case is made entirely of 3D carbon, a modern material offering strength and lightness. Its woven pattern, with vertical and horizontal strands, echoes the geometry of the case itself. This motif continues on the structured rubber strap, ensuring design continuity across the piece.

Precision as a principle
At the heart of the watch is the MHUB6023 calibre, offering a four-day power reserve. Its tourbillon at 6 o'clock includes a silicon escapement, designed to resist magnetic fields and temperature changes. The finish work on the bridges alternates satin and matte surfaces, bringing depth and refinement without excess.

With this new Square Bang Tourbillon, Hublot once again demonstrates its commitment to the Art of Fusion—bringing materials, design and innovation together in a contemporary and coherent timepiece.
