Hublot Big Bang Unico Titanium Ceramic 44mm Black 421.NM.1170.RX - BRAND NEW

The Hublot Big Bang Unico 421.NM.1170.RX represents one of the most accomplished expressions of modern haute horlogerie sport watchmaking. Introduced as part of Hublot's flagship Big Bang collection, the Unico line was created to showcase the brand's in-house manufacture capabilities, pairing an architecturally bold 44mm case with a skeletonized movement visible through the open-worked dial. This reference distills that vision into a disciplined palette of black and grey — a combination that has made it one of the most sought-after references in the Big Bang lineup.

At 44mm in diameter, the case is crafted from lightweight satin-finished titanium — a material prized in aerospace engineering for its exceptional strength-to-weight ratio. Titanium wears dramatically lighter on the wrist than stainless steel of the same size, allowing the Big Bang's substantial presence to remain comfortable across long wear sessions. The case architecture is unmistakably Hublot: bold porthole-style lugs, exposed screws at the case middle, and a multi-piece construction that gives the watch an almost industrial, mechanical beauty.

The black ceramic bezel is a defining element of reference 421.NM.1170.RX. Ceramic is virtually impervious to everyday scratches and retains its deep, matte-black color indefinitely — unlike coated metals that can wear through over time. The bezel's smooth, polished finish creates a refined contrast against the satin titanium case flanks, elevating the watch's visual sophistication well beyond pure sportswear territory.

The black dial features a compelling mix of index and Arabic numeral hour markers, lending the watch legibility and a purposeful aesthetic that suits both casual and dressy contexts. The dial architecture is designed to offer clear chronograph subdial readability alongside the main timekeeping functions, a hallmark of the Unico platform. The rubber strap — offered as original equipment on this reference — is ergonomically shaped to contour naturally to the wrist, and Hublot's proprietary strap-change system means it can be swapped for alternative options in seconds without tools.

Powering the Big Bang Unico is an in-house automatic chronograph movement — a significant achievement that places Hublot among a select group of brands capable of producing their own flyback or column-wheel chronograph calibers. The movement is visible through the exhibition caseback, rewarding the owner with an appreciation of the mechanical complexity within. The use of a manufacture movement in a watch of this caliber and price point reflects Hublot's commitment to vertical integration and craft.
