Powered by the Unico 2 Movement, designed to equip smaller chronographs and also open the world of Hublot to new enthusiasts. It retains the unique design of its former version with a double coupling system visible from the dial side as well as a 72-hour power reserve. But thanks to various technical optimizations, including the introduction of a new, flatter automatic winding system, it has been reduced by 1.3 mm in thickness.

The Hublot Square Bang features intriguing skeleton dial surrounded by a robust and highly scratch reistant satin finished Titanium case and Ceramic bezel with working screws. (not to be confused for decorative hardware.)

Time is shown using three sword-shaped, micro-blasted and satin-finished, luminescent hour, minute, and seconds hands and matching stylised hour markers.
