Hublot Spirit of Big Bang Titanium Coal Blue automatic blue dial rubber strap 42 mm

Spirit of Big Bang: Big Bang DNA in a tonneau architecture

With the Spirit of Big Bang, Hublot transposes the iconic codes of the Big Bang into a distinctive tonneau-shaped case, more architectural and sculptural in nature. This collection preserves the Big Bang’s spirit of innovation and contrast, while offering a different interpretation of its DNA, built around volume, verticality, and depth.

The Spirit of Big Bang Titanium Coal Blue 42 mm fits seamlessly into this continuity. It combines the collection’s emblematic tonneau architecture with an unprecedented, softer, and more contemporary shade, offering a new expression of the Big Bang universe.

Design & architecture: the strength of the tonneau shape

The tonneau-shaped case of the Spirit of Big Bang asserts a strong and immediately recognizable visual presence. Crafted in satin-brushed and polished titanium, it retains the aesthetic codes of the Big Bang, starting with the multi-layer construction, the six H-shaped screws on the bezel, and the taut-lined chronograph pushers.

The dial features a Coal Blue “carbon-effect” pattern, a strong visual signature that adds depth to the composition. Partial skeletonization reveals the movement, reinforcing the model’s technical and contemporary character. The chronograph counters integrate harmoniously into the dial structure, while the date positioned at 4:30 preserves balance and legibility.

HUB4700 chronograph movement

At the heart of the Spirit of Big Bang Titanium Coal Blue 42 mm beats the HUB4700 caliber, an automatic chronograph movement developed by Hublot based on the legendary Zenith El Primero. An absolute benchmark in high-frequency chronograph watchmaking, the El Primero is renowned for its precision and robustness—qualities fully expressed in this contemporary interpretation.

This movement operates at a high frequency of 36,000 vibrations per hour (5 Hz), enabling time measurement to 1/10th of a second, and offers a power reserve of approximately 50 hours.

Combining Zenith’s chronograph heritage with Hublot’s bold aesthetics, the HUB4700 caliber forges a strong link between traditional chronograph watchmaking and contemporary design, perfectly aligned with the spirit of the Spirit of Big Bang collection.

Proportions & wrist presence

With a width of 42 mm, the Spirit of Big Bang Titanium Coal Blue delivers a confident wrist presence, reinforced by the inherent verticality of the tonneau shape. The controlled case thickness, combined with carefully refined curves, allows the watch to sit naturally on the wrist.

This architecture gives the model a distinctive stature without compromising comfort. Water-resistant to 100 meters, the Spirit of Big Bang retains genuine versatility of use despite its sculptural design.

The Coal Blue color: a new visual softness

With the Coal Blue shade, Hublot introduces an unprecedented tone within the Spirit of Big Bang collection. This subtly greyed charcoal blue breaks away from the more aggressive colors traditionally associated with the Big Bang, without ever diluting its character.

Applied to both the dial and the strap, this hue softens the overall appearance and creates a subtle contrast with the power of the tonneau form and the rigor of the architecture. A contemporary chromatic approach, conceived to offer a more elegant and nuanced reading of the Big Bang DNA.

Titanium: lightness and robustness

The titanium case provides the Spirit of Big Bang Titanium Coal Blue with optimal wrist comfort. Lightweight, robust, and corrosion-resistant, this material is perfectly suited to a statement watch designed for everyday wear.

Satin-brushed and polished finishes highlight the geometry of the tonneau case and reinforce the architectural reading of the whole, while preserving the model’s durability and functionality.

Strap & functionality

The watch is fitted with a structured Coal Blue rubber strap, perfectly integrated into the tonneau case. True to Hublot’s DNA, this strap ensures flexibility, secure fit, and everyday comfort.

The quick-change system allows for easy strap replacement, while the titanium deployant clasp ensures precise and secure adjustment. Designed to accompany movement, this Spirit of Big Bang combines design, functionality, and genuine wearability.
