Hublot Spirit of Big Bang Titanium 45mm – Where Innovation Meets Elegance

Reference: 601.NX.0173.LR

Bold, lightweight, and mechanically sophisticated, the Hublot Spirit of Big Bang Titanium 45mm is a stunning testament to contemporary watchmaking. Its brushed and satin-finished titanium case, accented with polished beveled edges, exudes modern strength and sleek refinement.

At its core lies a transparent sapphire crystal dial that reveals the inner architecture of the movement. Brushed stainless steel hands with luminous-filled tips and skeletonized bases offer clarity and character. The applied hour markers, also brushed stainless steel with luminous fill, further enhance legibility and depth.

Surrounding the dial is a black inner bezel flange with a vivid red minute/seconds track that adds contrast and sporty edge. A small seconds sub-dial rests at 9 o’clock, while the skeletonized date wheel displays the current date between 4 and 5 o’clock—framed by a black background and blue border.
