Hublot Big Bang Original Chronograph Ceramic Blue 44mm Blue Dial Rubber and Alligator Leather Straps 301.CI.7170.LR - BRAND NEW Hublot Big Bang Original Chronograph Ceramic Blue…

The Hublot Big Bang Original Chronograph is the watch that rewrote the rules of luxury sport watchmaking. Introduced in 2005, the Big Bang fused polished and satin-finished case surfaces, exposed screws, an integrated rubber strap, and a porthole-inspired case architecture into a single silhouette that was unlike anything the Swiss industry had produced before. The reference 301.CI.7170.LR represents one of the most compelling executions of that original vision: a 44mm black ceramic case paired with a blue index dial, a combination that balances dramatic contrast with everyday wearability.

The case material tells much of the story. Black ceramic—referred to internally at Hublot as part of the Black Magic family—is prized for its exceptional scratch resistance, its deep non-reflective finish, and its surprisingly light weight relative to steel or gold. At 44mm the Big Bang commands the wrist with authority, yet the ceramic construction keeps the overall feel comfortable and unobtrusive across a full day. The case architecture features the signature six-screw bezel attachment and the H-shaped case flank screws that have become instantly recognizable hallmarks of the line.

The dial is where the 301.CI.7170.LR truly differentiates itself. The blue index dial introduces a rich chromatic tension against the all-black ceramic surround, drawing the eye immediately to the applied hour markers and the chronograph subdials. Blue has long been associated with depth, precision, and prestige in haute horlogerie, and Hublot's execution here—set against the matte ceramic darkness of the case and bezel—feels both contemporary and enduring. The overall legibility is excellent, with the chronograph layout arranged for clear, at-a-glance reading.

The strap configuration on this reference is itself a design statement: a rubber inner layer provides the cushioned, skin-friendly comfort and water-resistant practicality that active wearers demand, while the outer alligator leather facing elevates the pairing into genuine luxury territory. This dual-material construction is a signature Hublot approach, embodying the brand's founding philosophy of the Art of Fusion—the deliberate marriage of materials that tradition would never have combined. The strap integrates seamlessly with the case, reinforcing the Big Bang's monolithic, engineered aesthetic.

Powering the watch is an automatic chronograph movement, providing the precision and convenience of self-winding timekeeping alongside the functional chronograph complication. Hublot's manufacture and movement-integration expertise ensures the mechanism is both reliable and service-friendly, qualities that matter enormously for a timepiece intended to be worn regularly and passed down over time.
