Hublot Spirit of Big Bang Titanium 45mm – Bold Innovation in Lightweight Form
Reference: 601.NX.0173.LR
The Hublot Spirit of Big Bang Titanium 45mm is a striking blend of avant-garde design and technical excellence, housed in a brushed and satin-finished titanium case with polished beveled edges. This timepiece stands out for its bold presence while remaining remarkably lightweight and wearable.
The transparent sapphire crystal dial reveals the complexity of the movement beneath. Brushed stainless steel hands—luminous at the tips and skeletonized at the base—offer bold contrast and clear legibility. Applied stainless steel hour markers, also brushed and luminous-filled, create depth and symmetry around the dial.
A black inner bezel flange frames the dial with a vibrant red minute and seconds track, while a small running seconds sub-dial is positioned at 9 o’clock. The skeletonized date wheel is visible throughout, with the current date highlighted between 4 and 5 o’clock by a black background and blue border.
