Hublot Spirit of Big Bang Ceramic 45mm Watch 601.NM.0173.LR

The Hublot Spirit of Big Bang Ceramic 45mm (Ref. 601.NM.0173.LR) represents avant-garde evolution of the iconic Big Bang through distinctive tonneau case that combines titanium construction with ceramic bezel fixed by signature H-screws. The dimensional skeleton dial showcases the HUB4700 movement architecture whilst maintaining surprising legibility despite complex visual elements, creating fusion between traditional chronograph functionality and contemporary design innovation.

At 45mm with lightweight titanium construction, this provides substantial presence whilst the Grade 5 titanium offers superior strength-to-weight ratio with corrosion resistance and distinctive bluish metallic sheen when polished. The ceramic bezel with titanium H-screws creates signature Hublot fusion philosophy whilst the skeleton dial reveals intricate movement finishing.

The HUB4700 movement succeeds the legendary El Primero calibre with integrated automatic winding and 50-hour power reserve. The entirely skeletonised movement provides 1/10th second chronograph precision at 5Hz frequency whilst the silicon regulating elements ensure enhanced performance, precision, and reliability essential for demanding chronograph applications.

The black leather and rubber strap combination reflects Hublot’s fusion philosophy whilst the titanium folding clasp ensures secure attachment. The applied luminous indexes and hands maintain optimal legibility whilst touches of red accents create distinctive character against the skeleton architecture.

This Spirit of Big Bang Ceramic suits buyers seeking avant-garde chronograph design that pushes beyond conventional round case conventions. The tonneau case and skeleton dial create unique character within luxury sports chronographs whilst the titanium construction and HUB4700 movement demonstrate Hublot’s technical sophistication in distinctive contemporary form.
