This replica big bang black rubber carries the 301.CM.130.RX reference, a Big Bang in black ceramic paired with a matching rubber strap and black-tone hardware throughout. The “CM” code in Hublot’s naming system denotes a ceramic case with micro-blasted finishing, and the 130 suffix identifies the rubber strap variant with a steel-core deployant clasp. The result is an all-black package where case, bezel, dial, and strap blend into a continuous dark surface broken only by the luminous hour markers and the polished edges of the six H-shaped bezel screws. This monochromatic treatment makes the watch read as a single architectural object rather than a collection of separate components.

Ceramic cases maintain their surface condition across years of daily use because the material ranks significantly higher on the Mohs hardness scale than stainless steel.

What Collectors Notice

The 301.CM sits in Hublot’s original Big Bang case size, predating the 42mm and 45mm expansions, which gives it historical continuity within the collection. Ceramic versions of the Big Bang attract buyers who want the stealth profile that only a fully dark-material watch can provide. The bezel screws catch minimal light due to their reduced surface area, so the overall impression stays muted even in bright conditions. Compare the approach here with the Sang Bleu II in black at 45mm, which uses geometric case shaping to create visual interest from the same dark palette. Both occupy the Big Bang collection but solve the “all-black watch” challenge through different design strategies.

This vs Other Versions

All-ceramic Big Bangs exist in several references across the catalog, but the 301.CM.130.RX stands as the most restrained among them. No skeleton dial, no chronograph complications visible on the face, no color accents. The watch presents time through a clean matte-black surface with white luminous markers, and nothing more. For buyers who believe the Big Bang’s case design carries enough visual weight on its own, this reference proves that theory. This replica big bang black rubber is the reduced-to-essentials version of the ceramic Big Bang formula.
