THE CONTEMPORARY FUSION OF ULTRA-LIGHT TITANIUM AND RACING GREY

Like an architectural sculpture radiating a modern spirit, this watch projects profound luxury through its 45mm case crafted from high-grade Titanium – a material celebrated for its extreme lightness and superior corrosion resistance. The iconic interplay of satin-brushed surfaces and meticulously polished edges creates a multi-layered structure that is both robust and sharp. The signature Titanium bezel, secured by 6 H-shaped screws, affirms Hublot's unmistakable "Art of Fusion" DNA. Protected by glareproofed sapphire crystal with a water resistance of 50m, this resilient metal shell is beautifully paired with a gray lined rubber strap for a dynamic and elegant presence on the wrist of the elite collector.

GRAY SUNRAY DIAL – THE DEPTH OF REFINEMENT

The soul of this masterpiece resides in its elegant Gray Sunray satin-finished dial, which provides extraordinary visual depth. The serenity of the sophisticated gray canvas perfectly highlights the metallic sheen of the applied hour-markers and sharp baton hands. The dual chronograph sub-dials are balanced with technical precision at 3 and 9 o'clock, maintaining the characteristic elegance of the Classic Fusion collection. A discreet date window is positioned at 6 o'clock, ensuring modern utility without compromising the dial's aesthetic harmony. Every element guarantees absolute legibility under any lighting condition, delivering a highly modern, captivating, and timeless design language.
