The Hublot Spirit of Big Bang 42mm Blue Titanium 642.NX.7170.RX showcases Hublot’s signature tonneau case in satin-finished and polished titanium, offering bold presence with lightweight comfort.

Its blue skeletonized dial reveals the intricate chronograph movement beneath, featuring sub-dials at 3 and 9 o’clock, a date between 4 and 5, and luminous hands for strong legibility and depth.

Powered by the HUB4700 self-winding chronograph movement, it delivers a 50-hour power reserve and is visible through the sapphire caseback. A blue-lined rubber strap with titanium deployant clasp completes the sporty, modern aesthetic. Water-resistant to 100 meters, this piece blends contemporary design with high-performance mechanics.
