Product Overview This Hublot Spirit of Big Bang skeleton chronograph, reference 642.NX.0170.RX, is MS Factory’s racing-inspired flagship release.
It inherits all iconic design hallmarks of the Spirit of Big Bang collection, featuring a distinctive tonneau-shaped case that stands out from traditional round sports watches.
The core design philosophy follows Hublot’s "The Art of Fusion", blending titanium, ceramic and resin materials with a patented sandwich construction.
Core Craft & Technical Highlights 1.
Signature Sandwich Tonneau Case The case adopts a dual-material build of aviation-grade titanium and matte resin, fixed by six signature H-shaped screws all around the bezel, restoring the original layered fusion structure.
Every edge, screw slot and chamfer undergoes precise brushing and polishing for identical metallic texture as the genuine piece.
