Product Detailed Description

The HB Factory Hublot Big Bang Unico 421.OL.5180.RX combines a King Gold-tone case with deep blue elements, creating a striking contrast that reflects the bold, modern and highly recognizable character of the Big Bang Unico collection. Its 44mm case features a layered construction that delivers strong wrist presence and a distinctly architectural appearance.

The King Gold-tone case is paired with a microblasted blue ceramic-style bezel. Six signature H-shaped screws reinforce the iconic Big Bang identity, while the crown, chronograph pushers and side components contribute to the watch’s technical and sculptural design.

The matte blue skeletonized dial is the defining feature of this model. Its openworked layout reveals a complex mechanical structure with multiple visual layers. Applied hour markers, skeletonized hands, chronograph displays and the date window are carefully arranged to preserve readability while maintaining the technical appearance of the dial.

A blue rubber strap complements the bezel and dial, creating a cohesive overall design. It integrates naturally with the case and provides a secure, comfortable and well-balanced fit despite the substantial proportions of the watch.

With its distinctive two-tone combination, intricate openworked dial and unmistakable Big Bang construction, the HB Factory Hublot Big Bang Unico 421.OL.5180.RX is designed for collectors who appreciate oversized sports watches, exposed mechanical styling and bold contemporary color combinations.
