This replica spirit big bang 0170 white presents the 642.HX.0170.RX, a tonneau-shaped chronograph in white ceramic that stands out against the darker material palette dominating most Hublot catalogs. The HX code identifies white ceramic construction, which is denser and more complex to produce than standard black ceramic. At 42mm across and approximately 51mm lug-to-lug, the barrel-shaped case translates the Big Bang’s visual language into a non-round format. The skeleton dial reveals portions of the chronograph movement through cut-away sections, layering mechanical depth under the sapphire crystal.

White ceramic resists UV yellowing and maintains its color under sun exposure, a property that white-coated steel or gold cannot guarantee over years of wear. The tonneau shape means this piece reads differently from every angle as the case curvature catches light across a wider arc than a round watch.

Design & Finishing

The Spirit of Big Bang takes the brand’s signature layered construction and wraps it around a barrel case. Exposed screws on the bezel, visible gaskets between case layers, and the skeletonized dial all reference Big Bang design codes, but the tonneau shape changes how those elements interact on the wrist. The white ceramic version pushes the contrast further because every dark component, including the movement bridges and strap stitching, stands out against the pale case. Compare this to the blue-dial 642.NX.7170.RX in titanium for a study in how the same case architecture handles completely different materials. The full Spirit of Big Bang lineup covers titanium, ceramic, and King Gold variants, each shifting the tonneau template in a different visual direction.

On the Wrist

The barrel shape conforms to wrist curvature better than round cases, distributing contact across a longer surface. White ceramic adds visual lightness that darker materials cannot replicate, making this version wearable with summer wardrobes where a black ceramic chronograph would feel heavy. The skeleton dial provides constant engagement as light passes through the movement apertures at different angles. This replica spirit big bang 0170 white brings the tonneau chronograph into a material that refuses to fade or scratch.
