Hublot CLASSIC FUSION 525.NX.0170.LR Skeleton Dial 45mm

The open worked dial changes considerably depending on the lighting. Under direct light, the bridges, wheels and layered components create shadows that make the dial look deeper than a standard black surface. In softer indoor light, the watch becomes darker and more cohesive, with the titanium hands and chronograph markings providing the main points of contrast.

The skeleton construction is not designed for instant, effortless reading in the way a simple three-hand watch is. The visible mechanical parts create visual activity, particularly around the centre and chronograph registers. Once familiar with the layout, the display remains practical, but buyers who prefer a calm dial with large uninterrupted indexes may find it unnecessarily busy. Its appeal comes from being able to see how the watch is constructed rather than from visual simplicity.

How 45mm Wears?

At Hublot 45mm, the case has genuine wrist presence, but titanium makes the experience less tiring than a steel case of the same dimensions. The tonneau-inspired shape follows the wrist better than a completely flat square case, and the curved profile helps distribute the size across the arm. It still looks large, especially on a smaller wrist, but it does not feel as heavy as its proportions suggest.

This is best suited to medium and larger wrists, although buyers who intentionally prefer oversized watches may also enjoy it on a smaller wrist. The main issue is visual scale rather than physical comfort. The case occupies a significant portion of the wrist, so it works better as a statement piece than as a watch that disappears under a shirt cuff.

The Leather-and-Rubber Strap

The black alligator strap with a rubber interior gives this configuration a more refined character than a plain rubber strap. The outer surface works with the watch’s luxury positioning, while the rubber lining makes the strap more practical against the skin and better suited to regular wear. It also helps the watch feel less formal than a fully leather sports watch.

The strap is a strong part of the reference, but it does limit the styling range slightly. It suits black, grey, navy and casual tailoring naturally, while brightly coloured or highly formal clothing may create more contrast than some buyers expect. The folding clasp gives the watch a secure feel, although the large case and strap combination should be checked carefully for wrist comfort before purchase.

A Chronograph You Can See

The HUB1155 automatic skeleton chronograph is visible through both the open worked dial and the transparent case back, giving the chronograph function a more physical presence than it would have on a closed dial. The two sub-dials and central hands remain integrated into the open structure rather than being placed over a plain background. The movement offers an approximately 42-hour power reserve, while the chronograph allows elapsed-time measurement for driving, travel or everyday timing.

The practical compromise is legibility. The chronograph layout is attractive, but the exposed components can compete with the hands depending on the angle and light. This is a watch for someone who enjoys the mechanism as much as the function. If accurate instant reading is more important than mechanical visibility, a closed-dial chronograph would be easier to use.

Daily Use and Its Limits

The titanium case makes the watch suitable for regular wear, and the 50-metre water-resistance rating provides reasonable protection for daily activities. It should not be treated as a diving watch or worn carelessly around water. The open worked construction also means that dust, scratches and strap wear will become part of the ownership experience over time.

The case combines satin-finished and polished titanium, so light moves across the surfaces differently as the wrist changes position. This makes the watch look more dynamic in person than in a static product photograph. At the same time, polished areas can show marks more visibly, particularly on a large watch that may come into contact with desks, door frames and car interiors.

Who This Reference Suits?

The Hublot Classic Fusion 525.NX.0170.LR is suited to a buyer who wants a large, lightweight luxury watch with visible mechanical construction and a clear chronograph identity. It appeals to someone who prefers contemporary materials, open worked dials and a watch that attracts attention without relying on diamonds or bright colours.

It is less appropriate for someone seeking a discreet office watch, compact proportions or effortless legibility. The 45mm case and skeleton dial are deliberate design choices, not minor details. Compared with reference 525.NX.0170.RX, the leather-and-rubber strap gives this version a slightly more polished and versatile appearance, while the rubber version is more casual and practical for active use.
