Hublot Spirit of Big Bang 42mm...

The Spirit of Big Bang 42mm in titanium features a case and bezel constructed from micro-blasted titanium, a material chosen for its high strength-to-weight ratio and corrosion resistance. This finishing provides a uniform, matte grey surface that is both durable and understated. The blue rubber strap is secured with a deployant buckle clasp, also in titanium, ensuring a cohesive and comfortable fit. The dial is a skeletonized layout, revealing the intricate mechanics of the movement beneath the sapphire crystal, which is treated with an anti-reflective coating on both sides for optimal legibility. The tonneau-shaped case, a classic design element within Hublot’s modern collections, measures 42mm in width and is water-resistant to 100 meters, blending a traditional form with contemporary materials and execution. Powering the watch is the HUB1710 self-winding skeleton movement. This caliber operates at a frequency of 4 Hz (28,800 vibrations per hour) and offers a power reserve of approximately 50 hours. The primary complication is the chronograph function, activated via the column wheel and featuring a central seconds hand, a 30-minute counter at 3 o’clock, and a small running seconds at 9 o’clock. The skeletonization of the movement is not merely aesthetic; it is a technical process that involves strategically removing non-essential material from the base plate and bridges to reduce weight while maintaining structural integrity, allowing for a clear view of the regulating organ and the column wheel mechanism. The oscillating weight is also skeletonized to maintain this visual transparency. This particular reference, 642.NX.7170.RX, is in new, unworn condition with no visible imperfections. It is supplied with its original factory packaging and a valid e-warranty, which is Hublot’s current standard for documentation. The Spirit of Big Bang line occupies a distinct position in the luxury sports watch segment, offering Hublot’s signature “Art of Fusion” philosophy in a more compact and traditionally shaped tonneau case compared to the brand’s larger Big Bang models. Its use of titanium and a skeleton dial gives it a technical, modern appeal that has a strong following. For a collector, a new example of this model represents an opportunity to acquire a modern Hublot with a classic profile and a technically interesting movement, from a brand with a heritage-rich identity in innovative materials and bold design.
