Hublot Big Bang 421.NX.1170.RX.1104 Skeleton Dial 44mm

The Hublot Big Bang 421.NX.1170.RX.1104 stands out because of the way its skeleton dial changes the entire character of the watch. Instead of using a traditional dial layout, this configuration exposes the movement architecture and creates a more technical appearance where bridges, gears and mechanical details become part of the visual experience. The combination of a satin-finished titanium case, black rubber strap and openworked dial gives this 44mm Big Bang a modern presence that feels more like a performance-oriented luxury watch than a classic dress piece.

On the wrist, the 44mm size gives the watch a strong visual impact, but the lightweight titanium construction prevents it from feeling unnecessarily heavy. The case shape distributes its size well, especially because of the integrated strap design that follows the natural curve of the wrist. This configuration is best suited for buyers who enjoy larger watches with an architectural appearance and want something that immediately feels different from conventional chronographs.

Skeleton Dial That Defines This Reference

The openworked dial is the main reason buyers choose the Hublot Big Bang 421.NX.1170.RX.1104 over other versions. Under direct light, the exposed movement creates layers of depth, with different components appearing at different angles depending on how the wrist moves. In softer lighting, the dark skeleton structure becomes more subtle and gives the watch a more technical, monochrome appearance.

The transparent design also changes how the watch feels compared with standard Big Bang models. There is less separation between the exterior design and the mechanical side of the watch because the movement becomes part of the overall visual identity. Buyers who prefer clean and minimal dials may find the skeleton layout too busy, but enthusiasts who appreciate mechanical details will likely see it as the defining feature of this reference.

How The 44mm Case Wears?

The 44mm titanium case gives this Big Bang a larger wrist presence, but the material choice keeps the wearing experience comfortable. Titanium is noticeably lighter than steel, which helps reduce the feeling of bulk during longer periods of wear. The watch still has a bold profile, so it is better suited for medium to large wrists or buyers who intentionally prefer oversized sports watches.

The black rubber strap also plays an important role in daily comfort. It keeps the design sporty and flexible while matching the technical personality of the skeleton dial. This is not a watch designed to disappear under a shirt cuff; it is built to be noticed. However, the lightweight construction makes it more practical for regular wear than many large luxury watches with heavier metal bracelets

What Makes This Version Different?

Within the Big Bang Unico collection, the 421.NX.1170.RX.1104 appeals to buyers who want the mechanical appearance of a skeleton watch combined with a strong modern case design. Compared with a standard Big Bang Unico with a closed dial, this version provides a more expressive view of the movement and creates a more distinctive wrist appearance.

A similar reference such as the Hublot Big Bang Unico 421.NX.1170.RX offers a comparable titanium case and sporty construction, but the skeleton configuration of the 421.NX.1170.RX.1104 gives it a more technical identity. The difference is not only visual; it changes the entire ownership experience because the wearer interacts with the movement every time they look at the dial.

Movement And Daily Use

The Hublot Big Bang 421.NX.1170.RX.1104 uses the Unico movement architecture, designed with a visible chronograph mechanism that complements the skeleton dial concept. The movement layout is not hidden behind a traditional dial, making the mechanical construction one of the main reasons to own this watch.

For everyday use, this model works best for buyers who want a statement sports watch rather than a discreet daily companion. The rubber strap and titanium case make it practical, but the large dimensions and detailed dial mean it naturally attracts attention. It suits casual luxury styling, travel, events and collectors who enjoy watches with a strong visual identity.
