As of August 2026, Cazador has 0 verified price observations; the 2022 launch price was €17,500. Its differential trait: a sapphire dial that leaves the movement almost undecorated in view, with barely a trace of Hublot's usual Unico skeleton treatment.

The Big Bang Integral debuted in 2020 as the first Big Bang with an integrated metal bracelet, in a 42mm case running the Unico chronograph caliber. Two years later, at LVMH Watch Week in January 2022, Hublot introduced a version without the chronograph, more compact and slimmer: the Big Bang Integral Time Only, offered in titanium, 18-karat yellow gold, and a 250-piece limited edition in black ceramic.
The 40mm titanium case measures just 9.25mm thick, notably slim for a Big Bang, with 100 meters of water resistance. The bezel retains the family's signature six H-shaped titanium screws, with a composite resin insert sandwiched between the case and the bezel.
Instead of the typically skeletonized dial found on Unico models, this Time Only version has a sapphire crystal that gives a direct view of the top of Caliber MHUB1710, an automatic movement derived from the Zenith Elite 670 — Hublot and Zenith are sister brands within LVMH — finished with arabesque Geneva stripes and a skeletonized rotor. The exact power reserve remains unresolved between the sources consulted: Monochrome puts it at 50 hours and Fratello at 70, with neither offering further clarification.
The integrated three-link bracelet, with a triple folding clasp released by two pushers, reinforces this reference's sporty profile. The titanium version is not limited and remains available at Hublot boutiques and authorized retailers worldwide.
We don't have verified price observations for this reference. The 2022 launch price was €17,500, though we don't publish a current market range without backed data.
The original Big Bang Integral (2020) is a 42mm chronograph with the Unico caliber. The Time Only (2022) drops the chronograph, shrinks the case to 40mm, and uses the Zenith-derived MHUB1710 caliber for a slimmer profile.
Sources disagree: Monochrome states 50 hours and Fratello states 70 hours for the same reference. We can't confirm the exact figure with the documentation available.
The titanium version is not limited. Only the black ceramic execution within this same family launched as a 250-piece limited edition; the yellow gold version is also not limited.
Because, unlike the skeletonized Unico models, this Time Only version uses a sapphire crystal that gives a direct view of the top of the movement, with no added decorative dial.
It's rated to 100 meters, suitable for daily and sporting use.
It runs Caliber MHUB1710, derived from the Zenith Elite 670. Hublot and Zenith belong to the same group, LVMH, which facilitates this kind of technical collaboration between manufactures.
