Hublot Big Bang Unico 42 mm – Titanium, Titanium Ceramic, King Gold and King Gold Ceramic Models

The Hublot Big Bang watch with a Unico manufacture movement has now been redesigned on a smaller scale, to have a diameter of 42 mm.

In 2010, Hublot launched its new manufacture movement, the Unico chronograph, which was fitted in its iconic Big Bang model in 2013. Fully designed, developed, machined and assembled by Hublot’s own engineers, micro-mechanics, and watchmakers, the calibre Unico HUB 1242chronograph movement is equipped with a flyback chronograph mechanism, which can be reset at any time, is one of a kind in the industry. It stands out because of its double clutch mechanism and column wheel which can be seen from the dial side also having a removable platform escapement.

Five years later, the watchmakers from the Nyon manufacture have reworked the structure to offer a new Unico movement that is slimmer, giving it perfect dimensions for the 42-mm case of the new Big Bang.

Just like its big brother, the calibre HUB1280 keeps its double clutch mechanism and its column wheel can still be seen from the dial side. But, thanks to the removal of the platform escapement and the introduction of a new, flatter, self-winding system, it is 1.3mm thinner (for the same 30-mm diameter).

Building on the styling, reliability and robustness that made the HUB 1242 (8.05mm thick) such a success, the architecture of the new HUB1280 (6.75mm thick) has been entirely redesigned to facilitate its assembly and improve the wearer’s view of its operation through its dial and its windowed back cover.

Technical innovations for which four different patents have been filed, including an oscillating seconds clutch and an adjustable ball-bearing chronograph friction system.

The total number of components has increased from 330 to 354 parts; the new calibre having 43 rubies compared with 38 in the previous model. The Pellaton self-winding system has been replaced by a double reversing switch with ball bearings. The power reserve remains the same at 72 hours.

The arrival of this new manufacture chronograph movement enables Hublot to offer its Big Bang flagship model in this new 42-mm version. Its diameter has gone from 45 mm to 42 mm and the thickness of its case has been reduced from 15.45 mm to 14.5 mm. This new unisex watch is available in different versions including Titanium, Ceramic and King Gold finish.
