About this reference
The 451.NM.1170.NM uses the Big Bang Integral's 42 mm integrated format to set titanium against black ceramic. The titanium case and bracelet give the watch a continuous metallic structure, while the black ceramic bezel provides a sharp frame around the transparent skeleton dial. A sapphire crystal with anti-reflective treatment keeps the exposed chronograph layout clear, and the 100-metre rating supports the watch's robust, contemporary character.
Inside, the HUB1280 automatic movement brings a column-wheel chronograph with flyback function and date display. Its 43 jewels and 354 parts support a 72-hour power reserve, while the full rotor keeps the movement self-winding. The material pairing does the expressive work here: titanium carries the integrated shape, ceramic deepens the bezel, and the open-worked Unico calibre makes the technical structure visible from the front.
