Hublot Spirit Of Big Bang Blue (160..7170.LR NX)

The Hublot Spirit Of Big Bang Blue Ref. 601.NX.7170.LR is a bold, contemporary skeleton chronograph combining Hublot’s distinctive tonneau-shaped design with lightweight titanium construction and a highly technical open-worked dial.

Its transparent skeletonized dial exposes the mechanical architecture beneath, complemented by distinctive blue accents, applied hour markers, and luminous hands for improved legibility. The chronograph configuration includes a 30-minute counter, 12-hour counter, running seconds, central chronograph seconds, and date display, creating a highly technical appearance while maintaining the unmistakable character of the Spirit Of Big Bang collection.

At its heart is the automatic Hublot Caliber HUB4700, a high-frequency skeleton chronograph movement operating at 36,000 vibrations per hour and offering approximately 50 hours of power reserve. Its open-worked construction allows the intricate mechanics of the chronograph to remain visible from both the dial and exhibition caseback.

The substantial 45mm titanium case provides impressive wrist presence while remaining lightweight and comfortable compared with similarly sized stainless steel watches. The titanium bezel features Hublot’s signature exposed H-shaped screws, while sapphire crystals on the front and caseback provide a clear view of the movement.

The watch is paired with a blue crocodile leather strap, complementing the blue detailing throughout the dial and giving the sporty skeleton chronograph a refined luxury finish.

This example is presented in very good condition, showing light signs of careful wear, and comes as a full set with its original box and papers. A distinctive Hublot for collectors looking for lightweight titanium construction, bold tonneau styling, and an impressive high-frequency skeleton chronograph movement.
