Hublot Classic Fusion 521.NX.7071.RX 45 mm Grey Dial

The 521.NX.7071.RX turns the Classic Fusion into a restrained racing chronograph. Its 45 mm titanium case and bezel carry polished and satin surfaces, while the grey satin dial and matching grey rubber strap keep the palette cohesive. Sapphire with anti-reflective treatment protects the display, and luminous details help the chronograph remain legible. The watch is rated to 50 metres, giving the large case a practical footing without distracting from its measured, technical presentation.

The automatic HUB1143 adds the timing function to the Classic Fusion formula. It contains 59 jewels and 280 parts, uses a lateral chronograph coupling, and stores 42 hours of power. Hublot finishes the architecture, whose 28,800-vibrations-per-hour rhythm gives the watch a purposeful mechanical pulse. Titanium keeps the profile visually light, while the grey treatment makes the chronograph feel controlled rather than flamboyant.
