The Hublot Big Bang Unico (Ref. 421.NM.1170.RX) combines lightweight engineering with Hublot’s signature industrial design. The 42mm satin‑finished titanium case is paired with a black ceramic bezel, creating a durable and scratch‑resistant structure with excellent wrist comfort. The open‑worked dial reveals the Unico movement beneath, showcasing the column‑wheel at 6 o’clock and the bold, modern architecture that defines the Big Bang line. A structured black rubber strap completes the contemporary aesthetic.
Inside is Hublot’s in‑house HUB1280 Unico, a flyback chronograph movement offering a 72‑hour power reserve, column‑wheel control, and a slimmed‑down profile for improved wearability. The sapphire caseback displays the movement’s finishing and rotor design. With its blend of titanium, ceramic, and skeletonized mechanics, the 421.NM.1170.RX stands out as one of the most versatile and wearable Unico models in the collection.
