Hublot Big Bang Original Unico Titanium
Hublot Big Bang Original Unico Titanium 43mm 431.NX.1370.RX. Engineered for impact, the Big Bang Original Unico Titanium 43mm brings Hublot’s signature fusion philosophy into a refined, lightweight, and technically advanced package. Crafted from Grade 5 titanium, the 43mm case delivers modern durability while retaining the instantly recognisable Big Bang architecture: a multi‑layered construction, six signature H‑screws, angular crown guards and bold, functional detailing.
A deep black dial reveals a carbon‑inspired chequered pattern, cut to expose the heartbeat within: the in‑house Unico HUB1280 automatic chronograph movement. With a front‑facing column wheel, flyback functionality, and a 72‑hour power reserve, it embodies Hublot’s most advanced chronograph engineering. The openworked design adds depth and dynamism, showcasing the movement from both sides through sapphire crystal.
Fitted with a structured black rubber strap and Hublot’s One‑Click system, the watch ensures uncompromised comfort and easy versatility. At 43mm in diameter and 13.2mm thick, this model strikes the perfect balance between presence and wearability, rounding off a bold yet sophisticated interpretation of the modern Big Bang.
