Hublot Shaped Spirit of Big Bang Chronograph Titanium Pave 45mm 601.NX.0173.LR.1704

The Hublot Spirit of Big Bang is one of the most architecturally bold expressions in modern luxury watchmaking, and reference 601.NX.0173.LR.1704 represents the collection at its most spectacular. Introduced as a tonneau-shaped evolution of the iconic Big Bang round case, the Spirit of Big Bang distills Hublot's design language — exposed fasteners, layered case architecture, and an insistence on material innovation — into a form that feels simultaneously avant-garde and deeply wearable. The 45mm footprint commands the wrist with presence while the curved tonneau shape, unusual in a sport-chronograph context, ensures the case follows the natural contour of the wrist with surprising comfort.

At the heart of this reference's visual identity is the diamond-pavé bezel, which encircles the case in a constellation of precisely set brilliant-cut diamonds. Hublot's stone-setting artisans work directly on the titanium architecture, a notoriously demanding substrate given the metal's hardness, making the craftsmanship here genuinely exceptional. The pavé treatment does not soften the watch's sporty character — if anything, the contrast between raw, brushed titanium surfaces and the brilliance of the diamonds intensifies the watch's impact.

The skeleton index dial opens the watch entirely to the eye, allowing the movement's bridges, wheels, and chronograph architecture to serve as the dial itself. Index hour markers are retained to ensure legibility at a glance, but the emphasis is unmistakably on the mechanical spectacle beneath the sapphire crystal. This transparency is a recurring theme in Hublot's philosophy: the brand believes the movement is as much a design element as any external surface, and on the Spirit of Big Bang that conviction is expressed without compromise.

The 45mm titanium case, enriched with diamond setting, achieves something technically impressive: genuine lightness on the wrist despite its generous proportions. Titanium is roughly 45 percent lighter than stainless steel, meaning the 601.NX.0173.LR.1704 wears far less imposingly than its dimensions suggest. The rubber and leather composite strap continues Hublot's fusion DNA — natural rubber provides flexibility and resilience while leather brings a refined texture, and together they deliver a strap that is both secure and comfortable across long days.

Chronograph functionality adds practical dimension to this predominantly aesthetic statement. The pusher architecture integrated into the tonneau case flanks is engineered to maintain the clean lines of the Spirit of Big Bang silhouette without protruding awkwardly, a detail that underlines how carefully Hublot has adapted the chronograph complication to this non-round case shape. Collectors and enthusiasts who appreciate complications presented in unconventional geometries will find this reference particularly rewarding.
