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.
2. Fully Replicated HUB4700 Skeleton Movement
MS Factory precisely copies the exclusive HUB4700 skeleton chronograph movement. Visible open-work mechanical gears through the hollow dial, complete with full chronograph functions: 30-minute counter, 12-hour counter, date window, accurate sweep second hand. Stable timekeeping, no obvious flaws when inspecting the movement details.
3. One-Click Quick Release Strap System
Comes with custom ribbed fluororubber sport strap paired with original-style folding clasp. Built-in quick-switch mechanism: simply press the side button to detach and swap straps in seconds without extra tools. The rubber band offers soft, sweat-resistant daily wear for sports and casual occasions.
