Hublot Big Bang Partnerships Tourbillon SR_A by Samuel Ross Titanium 44mm 428.NX.0101.RX.SRA23 - BRAND NEW

The Hublot Big Bang Partnerships Tourbillon SR_A by Samuel Ross is the product of one of contemporary watchmaking's most compelling creative dialogues—a formal collaboration between Hublot, the Geneva-based manufacture celebrated for fusing unexpected materials with high complications, and Samuel Ross, the London-born designer and founder of A-COLD-WALL* whose practice bridges architecture, industrial design, and fine art. Reference 428.NX.0101.RX.SRA23 is the physical result of that conversation: a 44mm tourbillon that reads as a wearable object of design as much as a precision instrument.

The Big Bang family has been Hublot's creative canvas since its debut in 2005, establishing the porthole-shaped case with six H-shaped screws on the bezel as an instantly recognisable silhouette in luxury watchmaking. Over nearly two decades, the line has hosted everything from ceramic and sapphire cases to collaborations with artists, athletes, and cultural figures, and the SR_A edition belongs firmly to that tradition of purposeful partnership. The 44mm case size sits at the heart of the Big Bang range, offering substantial wrist presence while remaining the most legible and well-proportioned expression of the design.

The case of 428.NX.0101.RX.SRA23 is crafted from titanium—a material prized in high-end watchmaking for its exceptional strength-to-weight ratio, hypoallergenic properties, and subtly warm grey lustre. The bezel is set with diamonds, introducing a layer of precious contrast against the industrial titanium and the bold graphic language Samuel Ross brings to the project. The signature skeleton dot dial reflects Ross's visual vocabulary: structural, abstracted, and unapologetically contemporary, with the movement's tourbillon complication visible as both a technical statement and a sculptural focal point. The black rubber strap, a hallmark of Big Bang ergonomics, ensures the watch wears comfortably and securely.

At the mechanical heart of this piece sits a tourbillon movement—watchmaking's most storied anti-gravity complication, invented to counteract the effects of Earth's gravitational pull on a pocket watch movement and today prized as the supreme demonstration of a manufacture's technical mastery. Seeing the tourbillon cage through the open architecture of the SR_A dial is entirely intentional: Ross's design philosophy treats the mechanism not as something to be hidden but as a core design element, turning every glance at the dial into an encounter with the watch's engineering.

Owning reference 428.NX.0101.RX.SRA23 means possessing a piece that operates simultaneously in the worlds of luxury horology, collector culture, and contemporary design. The SR_A collaboration is a numbered, finite edition, and demand among both Hublot enthusiasts and fans of Samuel Ross's broader creative output ensures that examples at retail price represent genuine long-term value. Presented here brand new, this watch arrives in pristine, unworn condition, ready for its first owner.
