Overview
The Hublot Big Bang Unico Titanium 45 (ref. 411.NX.1170.RX) pairs a 45 mm brushed titanium case with the manufacture's own Cal. HUB1242 Unico flyback chronograph movement. Its matte black skeletonised dial lays the movement's architecture bare, a defining trait of the Big Bang Unico generation. The result is a bold yet technically coherent sports watch that sits at the heart of Hublot's in-house movement programme.
History
Hublot introduced the Unico calibre as a statement of manufacture independence, and the Big Bang Unico Titanium 45 was among the references that brought this movement to a broad audience from 2013 onward. The titanium case variant appealed to collectors who favoured the material's lightness and corrosion resistance over the prestige of precious metal. Production of this reference ran through approximately 2019, during which time it served as a benchmark entry point into the Unico family. Its relatively long production run reflects the sustained collector interest in the skeletonised, in-house-movement configuration.
Notable points
- Case material is grade titanium, offering a notably light wearing experience for a 45 mm sports chronograph.
- Cal. HUB1242 Unico is a column-wheel flyback chronograph movement developed and manufactured in-house by Hublot.
- The matte black skeleton dial exposes the movement's bridges and wheels, eliminating the traditional dial layer entirely.
- A lateral clutch mechanism in the Unico calibre allows the chronograph to be integrated into the movement architecture rather than added as a module.
- Production spanned roughly 2013 to 2019, giving the reference a sustained presence in the Big Bang catalogue.
