The Hublot Spirit of Big Bang Chronograph Diamond is the high-jewelry evolution of Hublot’s famous “tonneau” (barrel-shaped) collection. It combines the aggressive, skeletonized look of the Spirit line with a bezel set with brilliant-cut diamonds, creating a piece that is both a technical machine and a luxury accessory.
In the UAE, this model is particularly popular in the “Pavé” or “Diamond Bezel” configurations, often seen at high-end events in Dubai as a bold alternative to traditional round watches.
1. The Tonneau Case & “Sandwich” Construction
Unlike the standard round Big Bang, the Spirit of Big Bang uses a curved, barrel-shaped case. It utilizes Hublot’s “sandwich” construction, allowing for a mix of materials—such as Titanium or 18k King Gold—to be layered together. The diamonds are typically set into the bezel, which is secured by the signature 6 H-shaped titanium screws.
2. Skeletonized Sapphire Dial
The dial is a transparent sapphire disc that reveals the intricate mechanical “engine” underneath. This includes:
-
Skeletonized Date Disc: The date numerals are visible as they rotate around the dial, landing on a white contrast window at 4:30.
-
Three Sub-dials: Chronograph counters (seconds, minutes, and hours) that appear to “float” above the movement.
3. High-Frequency “El Primero” Heart
Inside is the HUB4700 movement, which is based on the legendary Zenith El Primero. It beats at a high frequency of 5 Hz (36,000 vibrations per hour), allowing for 1/10th of a second precision in the chronograph—a rarity in luxury sports watches.
4. Diamond Setting
-
Bezel Diamonds: Usually features between 48 and 156 brilliant-cut diamonds (depending on the case size), totaling approximately 0.90ct to 1.34ct.
-
Pavé Versions: Higher-tier “Pavé” models also have the entire case body encrusted with hundreds of diamonds.
