Hublot Big Bang Unico 44mm Black Magic 421.CI.1170.RX SKELETON BLACK RUBBER

The Big Bang Unico 44mm Black Magic utilizes a monochromatic aesthetic constructed from microblasted black ceramic, a material known for its enduring hardness and scratch resistance. This case and bezel are finished with a satin-brush technique, creating a consistent matte texture that is both traditional in its application and modern in its execution. The dial is a full skeleton, offering a direct view of the movement’s mechanics, framed by a black flange with applied polished indices. The strap is a classic black rubber design, secured with a black-plated deployant buckle clasp that matches the case’s finish. This design approach results in a cohesive and timeless appearance, rooted in Hublot’s heritage-rich “Art of Fusion” philosophy that combines advanced materials with traditional watchmaking architecture.

Powering the watch is the Hublot HUB1242 Unico manufacture movement, a self-winding chronograph caliber with a 72-hour power reserve. This column-wheel chronograph is fully integrated, with the mechanism positioned on the dial side, which is clearly visible through the skeletonized structure. The movement features a dual-direction rotor and operates at 28,800 vibrations per hour (4 Hz). The primary complication is the flyback chronograph, which allows for instantaneous resetting and restarting of the timing function without needing to stop the mechanism first. The date window is discreetly positioned at 3 o’clock. The movement’s bridges and plates are sandblasted and adorned with black coatings, maintaining the watch’s unified color scheme while showcasing its technical functionality.

This specific reference, 421.CI.1170.RX, is in new, mint condition with no signs of wear. It is accompanied by its full set of documentation, including the manufacturer’s e-warranty, which provides a straightforward and easily accessible record of its authenticity and service history. Within the Hublot collection, the Big Bang Unico series represents a core model line, and this Black Magic iteration is a sought-after variant due to its all-black construction and technical presentation. The use of ceramic, combined with the in-house Unico movement, positions this watch as a significant and collectible modern sports chronograph. Its market position is stable, appealing to collectors who value Hublot’s material innovation and a design that remains classic within the brand’s contemporary identity.
