The Square Bang collection is characterised by its new, disruptive, and unconventional shape, representing an evolution of the brand’s DNA and literally squaring the circle of the iconic port hole shape.

This Square Bang Unico model features the Unico 2 calibre, designed to equip smaller chronographs with the power of the original movement. Thanks to technical optimisations, the movement has been reduced by 1.3mm in thickness, while still retaining key features such as a double coupling system, which can be viewed from the side of the dial, as well as a 72-hour power reserve.


Designed to move with precision, this striking model makes an instant impact with a sapphire crystal dial, featuring 18K King gold details, two chronograph sub-dials, and a date display.

Presented in a 42mm satin-finished and polished 18K King gold case secured with a robust black structured rubber strap, this timepiece is protected by sapphire crystal with anti-reflective treatment.

Powered by the expert in-house HUB1280 UNICO manufacture self-winding chronograph flyback movement, this high-performance timepiece is water resistance to 10 bar (100 metres).
