About this reference
The 642.NX.0170.RX carries the Spirit of Big Bang's shaped-case chronograph idea in a 42 mm titanium design. Polished and satin surfaces articulate the case and bezel, while the skeleton dial exposes the visual density of the chronograph beneath the sapphire crystal. A black rubber strap keeps the palette direct, and the titanium deployant buckle continues the material logic. With anti-reflective sapphire and 100 metres of water resistance, the watch pairs its unusual silhouette with practical strength.
The automatic HUB4700 is a high-beat chronograph with a column wheel, date display, and small seconds. Its silicon regulating element beats at 36,000 vibrations per hour, while 31 jewels and 278 parts support a 50-hour reserve. The Zenith-derived architecture is finished in a skeletonized industrial style. This Spirit of Big Bang places its mechanical structure in view, from the open dial to the movement visible through the caseback.
