Hublot Spirit of Big Bang 42mm Yellow Magic 642.CY.011Y.RX SKELETON YELLOW RUBBER

The Spirit of Big Bang 42mm Yellow Magic, reference 642.CY.011Y.RX, is distinguished by its vibrant yellow ceramic case, a material Hublot has perfected through a proprietary sintering process that achieves a saturated, scratch-resistant color unattainable with traditional coatings. This sophisticated tonneau-shaped case is paired with a yellow rubber strap, creating a cohesive and modern aesthetic. The design centers on a skeletonized dial that offers a clear view of the movement’s intricate mechanics. The finishing on the components is impeccable, with polished bevels on the bridges and gears contrasting against satin-finished surfaces, all framed by a black polished ceramic bezel with H-shaped titanium screws. This combination of advanced materials and openworked architecture defines the watch’s technical personality.

Powering the watch is the HUB1710 automatic movement, which is based on a Zenith Elite base caliber. This skeletonized movement is visible from both the dial side and through the sapphire crystal case back, revealing its oscillating weight and the meticulous decoration applied to its components. The primary complication is a central chronograph function, operated via the pushers integrated into the case structure, which allows for precise timing of elapsed intervals. The movement offers a power reserve of approximately 50 hours. The legibility of the chronograph totalizers and small seconds sub-dial is maintained despite the openworked design, a testament to thoughtful layout and execution.

This particular example is in new, mint condition, with no signs of wear on the case, bezel, crystal, or strap. It is a complete set and includes its electronic warranty, or e-warranty, which facilitates straightforward registration and authentication with Hublot. Within the collector’s market, the Spirit of Big Bang line represents a more contemporary and architecturally complex alternative to the classic Big Bang, and this Yellow Magic reference is particularly notable for its use of colored ceramic. Its 42mm case size also offers a versatile wearing experience. As a new, unworn example of a technically advanced model from a highly recognizable brand, it represents a sound acquisition for a collector seeking a modern sports chronograph with a distinctive material and color profile.
