Hublot Big Bang Reloaded: A Bold Evolution of the Iconic Chronograph

Introducing the Big Bang Reloaded

Hublot has taken its iconic Big Bang line to the next level with the launch of the Big Bang Reloaded collection. This new series builds on the success of the Big Bang Original and the Big Bang Unico, combining the best of both worlds: the bold, avant-garde design of the original Big Bang, the layout of the Big Bang Original, and the intricate skeletonization of the Unico chronograph. The result is a watch that is more aggressive, more technical, and undeniably more 'explosive'—just as the name suggests.

The collection launches with five standard models and two limited editions, all housed in a 44mm case with a thickness of 14.5mm and water resistance to 100 meters. The standard models include Magic Gold, Titanium-Ceramic, All Black Ceramic, Blue Ceramic, and Dark Green Ceramic. The limited editions feature a white ceramic model dedicated to football star Kylian Mbappé and a carbon fiber model for sprint legend Usain Bolt.

A Dial That Demands Attention

The dial of the Big Bang Reloaded is a masterclass in horological design. Large Arabic numerals appear to float above a laser-cut date disc, while the signature Hublot hands are as bold and readable as ever. The most notable change from the Big Bang Unico is the repositioning of the date window to the 4:30 position, a move that declutters the 3 o'clock area and allows the 60-minute counter to breathe. The date window is now marked with a pointed arrow, creating an asymmetrical balance that adds character.

Hublot has also added a technical touch by coloring the column wheel and horizontal clutch in the same hue as the date arrow, and even printing their English names on the dial—a nod to watchmaking nerds who appreciate the mechanics. On all models except the All Black, the central chronograph seconds hand, minute counter, and tachymeter scale are highlighted in a vibrant color that matches the case, making the chronograph function easy to read at a glance.

The Heart: HUB1280 Unico Movement

Powering the Big Bang Reloaded is the second-generation Unico caliber HUB1280, a movement that Hublot proudly showcases. This automatic chronograph operates at a frequency of 28,800 vibrations per hour and offers a 72-hour power reserve. Compared to the first-generation Unico, the HUB1280 is significantly slimmer—6.75mm versus 8.05mm—thanks to an optimized automatic winding system and the removal of the detachable escapement module, which was rarely used in practice.

With the launch of the Reloaded, Hublot has also revealed the five patents behind this movement, underscoring its technical sophistication:

Patent 1: A horizontal clutch with elastic teeth, manufactured using LIGA lithography and electroforming. The teeth are angled at 3 degrees and feature shock absorption, ensuring smooth engagement without chronograph hand wobble.
Patent 2: A new reversing mechanism in the automatic winding system that reduces friction and wear when the rotor changes direction.
Patent 3: A jewel bearing with ceramic balls for the chronograph seconds wheel, preventing hand shudder when the chronograph starts.
Patent 4: A new silicon escape wheel and pallet fork that are anti-magnetic and improve precision.
Patent 5: A new minute wheel design that prevents the minute hand from jumping when the crown is pulled or pushed.

Warranty and Buying Advice

The HUB1280 has proven its reliability over time, and Hublot is backing it with an extended warranty: for watches purchased after January 1, 2026, customers receive a 10-year warranty—5 years standard plus an additional 5 years upon online registration. This is a strong indicator of Hublot’s confidence in the movement’s durability.

For collectors and enthusiasts, the Big Bang Reloaded is a compelling choice if you appreciate bold design, technical innovation, and the fusion of materials. The limited editions, especially the Mbappé and Bolt models, are likely to become collectible items. When purchasing, ensure you buy from authorized dealers to guarantee authenticity and warranty coverage. Also, consider the case size—44mm is substantial, so it suits larger wrists or those who prefer a commanding presence.

While the movement is already impressive, some purists might wish for a free-sprung balance spring in the future—a feature that would elevate it to even higher levels of precision. But as it stands, the Big Bang Reloaded is a worthy addition to Hublot’s lineup, offering a fresh take on a modern classic.
