Why collectors want this Square Bang
The Square Bang Unico Titanium Ceramic is where Hublot takes the iconic Big Bang language and turns it into a bold square statement. The 42 mm titanium case keeps the watch light on the wrist, while the black ceramic bezel and sapphire dial showcase the in house Unico movement in full view. It feels modern, technical, and unmistakably Hublot from across the room.
Powered by the HUB1280 automatic flyback chronograph caliber with around 72 hours of power reserve, this reference delivers serious watchmaking along with everyday usability at 100 meters of water resistance. As a full set with box and papers, it is exactly what serious Hublot collectors look for when they want a Square Bang that presents as a complete, high confidence example.
