Hublot Spirit of Big Bang Ref# 601.NM.0173.LR

The Hublot Spirit of Big Bang Titanium Ceramic Ref. 601.NM.0173.LR is a bold reinterpretation of Hublot’s signature design, reimagined in a striking tonneau-shaped case that perfectly embodies the brand’s “Art of Fusion” philosophy. Combining lightweight yet robust titanium with polished black ceramic, this 51mm x 45mm chronograph represents innovation, power, and avant-garde craftsmanship at its finest.

The multi-layer case architecture, secured by Hublot’s iconic six H-shaped screws on the ceramic bezel, gives the watch a distinctive, architectural presence on the wrist. The skeletonized dial reveals the technical artistry of the HUB4700 automatic chronograph movement, a high-frequency caliber based on Zenith’s legendary El Primero, beating at 36,000 vibrations per hour. With a power reserve of approximately 50 hours, this movement offers not only remarkable accuracy but also a visually captivating mechanical performance.

The dial features chronograph counters, a small seconds subdial, and a date display, all harmoniously integrated within the open-worked structure. Luminous gold-plated hands and hour markers ensure excellent legibility against the dramatic skeleton backdrop. Some variations of this reference highlight bold orange accents, further enhancing its sporty and contemporary appeal.

The watch is paired with a black alligator leather strap stitched onto black rubber, combining elegance with durability and comfort — a hallmark of Hublot’s innovative material fusion. The sapphire case back reveals even more of the HUB4700’s intricate finishing, while anti-reflective sapphire crystal on the front provides a clear view of the dial from every angle.
