Hublot · Family: Spirit of Big Bang
The Hublot Spirit of Big Bang Titanium (ref. 641.NX.0173.LR) is a 42mm titanium chronograph with a tonneau-shaped case, the line Hublot launched in 2013 as a shape reinterpretation of the original round Big Bang. It runs Caliber HUB4700, an automatic column-wheel chronograph derived from Zenith's El Primero caliber. Cazador has no verified price observations yet for this reference. Its stand-out detail: the tonneau case combines straight and curved lines in a single silhouette, a more complex construction than the Big Bang's standard circular case.

Hublot introduced the Spirit of Big Bang line in 2013 as a shape reinterpretation of its Big Bang collection, launched in 2005: instead of the original circular case, it adopts a tonneau silhouette combining straight and curved sections, a construction with more surfaces and angles that complicates polishing and assembly compared with a conventional round case.
This reference, 641.NX.0173.LR, houses Caliber HUB4700, an automatic column-wheel chronograph that Hublot derives from Zenith's El Primero caliber — a brand that, like Hublot, has belonged to the LVMH group since 1999 and 2008 respectively — adapted to the manufacture's own architecture and finishing. The result keeps the El Primero's signature frequency, 36,000 vibrations per hour (5 Hz), a high figure that in chronograph work allows measuring intervals down to 1/10 of a second.
With a 42mm titanium case, the Spirit of Big Bang Titanium keeps Hublot's materials-fusion identity but in a monochrome format, without the ceramic inserts or color details of other executions in the line. The strap uses Hublot's One Click interchangeable system, allowing tool-free swaps.
This is the fourth Hublot reference Cazador adds, extending the brand's catalog with the Spirit of Big Bang line alongside the Big Bang Unico and the two Classic Fusion references already present.

The Spirit of Big Bang, launched in 2013, adopts a tonneau-shaped case combining straight and curved sections, versus the circular case of the original 2005 Big Bang.
Hublot derives the HUB4700 from Zenith's El Primero caliber, adapting it to its own architecture and finishing. Both brands belong to the LVMH group, which facilitates this kind of technical collaboration between manufactures within the group.
36,000 vibrations per hour (5 Hz), the same signature frequency as the El Primero caliber it's derived from, which allows measuring chronograph intervals down to 1/10 of a second.
Yes, it uses Hublot's One Click system, which allows the strap to be removed and swapped without tools.
Roughly 50 hours, a standard figure for an automatic chronograph in this category.
It reaches 100 meters of water resistance, enough for daily wear and swimming, though it isn't designed as a technical dive watch.
