Hublot · Family: Big Bang
The Hublot Big Bang Unico Sky Blue 441.EX.5120.RX is a limited edition of 200 pieces introduced in 2023, with a 42mm light blue ceramic case and bezel. It runs the in-house Calibre HUB1280, a column-wheel flyback chronograph with roughly 72 hours of power reserve. Cazador has no verified price observations yet. Its standout detail is precisely that light blue ceramic tone, unusual within the Big Bang Unico catalog, and its limited run of only 200 watches.

The Big Bang Unico is the in-house-chronograph execution within Hublot's Big Bang family, the line that, since its 2005 launch, defined the brand's identity around the 'fusion' of unconventional materials in fine watchmaking — rubber, ceramic, composites — with 42mm cases and a six-H-shaped-screw bezel.
In 2023, Hublot introduced the Big Bang Unico Sky Blue, a limited edition of 200 pieces that pushed that language into a new light blue ceramic tone, applied to both case and bezel, with white ceramic lateral protectors adding contrast. The openworked dial reveals the chronograph's column wheel through an aperture at 6 o'clock, with a light blue 60-minute chronograph counter at 3 and a running-seconds counter at 9.
Inside is the in-house Calibre HUB1280, an automatic column-wheel flyback chronograph movement developed entirely by Hublot, with 354 components and 43 jewels, beating at 28,800 vibrations per hour and delivering roughly 72 hours of power reserve — well above the 42-48 hours typical of many externally sourced automatic chronographs.
The watch ships with two straps via Hublot's One-Click quick-change system: a structured light blue rubber strap with a white lining and titanium deployant clasp, and a white calfskin strap with Velcro fastening, intended as a more casual alternative.
The edition, limited to 200 numbered pieces, joins other Big Bang Unico executions already in Cazador's catalog, widening the family's ceramic color range beyond the usual black and white tones.

It's a traditional control mechanism in high-end watchmaking that coordinates the chronograph's start, stop and reset functions with more precision and smoothness than simpler cam-based systems.
Two: a structured light blue rubber strap with a white lining and titanium clasp, and a white calfskin strap with Velcro fastening, swappable via the One-Click system.
