# Hublot Classic Fusion Aerofusion – A Bold, Light‑As‑Air Skeleton Chronograph Hublot’s Classic Fusion line has always been about marrying daring materials with clean, contemporary aesthetics, and the 2015‑launched Classic Fusion Aerofusion pushes that philosophy to an extreme. At first glance the all‑black 45 mm ceramic (or titanium) case commands attention, while the fully skeletonized sapphire dial offers an unapologetically “show‑off” view of the HUB1155 automatic chronograph inside. The watch promises a lightweight, sporty feel despite its sizeable dimensions, and it delivers a striking wrist presence that is hard to ignore. Yet, beneath the flash there are a few practical compromises that make the Aerofusion more of a statement piece than an everyday workhorse. Below we break down the design, movement, wearability, and value to see whether the hype holds up. ## Design & Case The Aerofusion’s case measures a generous 45 mm in diameter, a size that Hublot describes as “balanced” even at that scale. Constructed from black ceramic—an exceptionally hard, scratch‑resistant material—the case feels surprisingly light, a point repeatedly highlighted by reviewers: “Lightweight ceramic case feels light on the wrist despite its 45 mm diameter.” The finish is a mix of polished surfaces and satin‑brushed accents, giving the watch a dual‑tone texture that catches the eye from every angle. A full‑size sapphire crystal protects the dial, which is entirely skeletonized. The open‑worked dial is not just a decorative gimmick; it provides an unobstructed view of the HUB1155 movement, making the watch feel like a living piece of engineering. As one reviewer put it, “The skeleton dial looks great,” and the readability remains decent thanks to well‑placed hour markers and contrasting sub‑dial outlines, even though the watch lacks any lume on the dial or hands—a notable drawback for low‑light situations. The strap is a high‑grade rubber band, chosen for its flexibility and comfort. It pairs well with the case’s sporty language and is secured with a deployant clasp. While the clasp functions reliably, some users have expressed discomfort: “The clasp design could worry some wrists.” The watch is water‑resistant to 50 m, sufficient for everyday splashes and hand‑washing, but Hublot advises against swimming or water sports: “It’s fine for everyday splashes and hand washing, but it’s best to avoid swimming or water sports.” ## Movement & Performance At the heart of the Aerofusion sits the HUB1155 self‑winding skeleton chronograph, a proprietary Hublot caliber that combines automatic winding with a visible chronograph train. The movement is fully exposed through the dial’s skeleton, allowing the wearer to watch gears and bridges dance in real time. Power reserve sits at roughly 42 hours, which is “modest compared to competitors” and means the watch will need to be wound or worn daily to stay fully powered. Accuracy has not been a focal point in the public reviews, but the HUB1155 is built to Hublot’s in‑house standards, delivering the reliability expected of a luxury automatic. The chronograph functions are smooth, and the mechanical feel is reinforced by the audible “click” of the pushers, adding to the tactile satisfaction of operating a true mechanical timer. ## On the Wrist Despite its 45 mm footprint, the Aerofusion manages to sit comfortably thanks to the lightweight ceramic case and the forgiving rubber strap. Reviewers consistently note the “surprisingly comfortable” feel, even on larger wrists. The lug‑to‑lug spread is proportionate to the case size, providing a balanced silhouette that does not overhang the wrist dramatically—an important consideration for those who shy away from overly “boxy” watches. However, the watch is not universally flattering. The same 45 mm diameter that gives it a bold presence can feel “large for smaller wrists,” potentially overwhelming those with a more delicate wrist profile. The lack of lume on the dial and hands further limits its practicality after dark, forcing the wearer to rely on external lighting or a secondary time‑telling device. The deployant clasp, while secure, has been described as “uncomfortable for some users,” especially during extended wear or when the strap is fully tightened. Overall, the Aerofusion excels as a conversation starter and a piece that showcases Hublot’s material experimentation, but it demands a wrist that can accommodate its size and a lifestyle that does not require night‑time readability or deep water exposure. ## Value & Verdict Hublot does not publish an official retail price for the Classic Fusion Aerofusion, but its positioning can be inferred from the brand’s broader lineup. A comparable model, the Classic Fusion 42, retails around **US $8,400**, placing the Aerofusion firmly in the high‑end luxury segment. Given its premium materials (black ceramic or titanium, sapphire crystal, rubber strap) and in‑house skeleton chronograph movement, the price expectation aligns with other boutique‑level chronographs. From a value perspective, the watch offers a unique blend of visual drama and lightweight construction that few competitors can match at this price tier. The strengths—lightweight case, striking skeleton dial, comfortable rubber strap, and bold wrist presence—are balanced by notable compromises: a large case that may not suit all wrists, lack of lume, a modest 42‑hour power reserve, and a clasp that can feel abrasive. For collectors who prize aesthetic impact and the novelty of a fully exposed movement, the Aerofusion delivers a rewarding experience and earns an **overall rating of 8.25/10** as cited by reviewers. **Final take:** The Hublot Classic Fusion Aerofusion is a daring, technically competent chronograph that excels as a statement piece. It shines brightest on wrists that can accommodate its 45 mm stature and in environments where daytime visibility is paramount. If you’re seeking a watch that combines avant‑garde materiality with a transparent mechanical heart, and you’re comfortable with its size and night‑time limitations, the Aerofusion is a worthy addition to a luxury collection. For those who prioritize subtlety, lume, or extended power reserve, there are more pragmatic options within the same price bracket.
