About This Reference
The Spirit of Big Bang takes Hublot's founding "Art of Fusion" philosophy and reshapes it into a tonneau case — a departure from the round Big Bang that gives the collection its own identity on the wrist. The 641.NM.0173.LR pairs a satin-finished titanium case with a microblasted black ceramic bezel secured by six signature H-shaped titanium screws, while black composite resin lateral inserts reinforce the material contrast that defines the brand. Behind the sapphire crystal dial, the HUB4700 movement — built on the legendary Zenith El Primero architecture — beats at a high-frequency 36,000 vph, delivering chronograph precision with a skeleton presentation that puts the mechanics on full display. It is a watch that makes no attempt to be subtle, and is all the better for it.
