Hublot Big Bang Integrated Time Only 40mm Sky Blue Ceramic 456.EX.5120.EX SKELETON CERAMIC

The Hublot Big Bang Integrated Time Only 40mm in sky blue ceramic features a case and integrated bracelet manufactured entirely from polished ceramic, a material known for its enduring scratch resistance and lightweight properties. This model utilizes a monobloc construction for the case, which is then finished with a combination of polished and satin-brushed surfaces on the bracelet links to create visual depth. The dial is a skeletonized design, revealing the underlying movement components through a sky blue tinted sapphire crystal. This approach provides a clear view of the mechanics while maintaining a cohesive color theme. The use of ceramic and the integrated bracelet design give the watch a modern interpretation of a classic sports watch silhouette, drawing from Hublot’s heritage-rich focus on material innovation.

Powering the watch is the HUB1710 self-winding movement, which is visible through the skeleton dial and the sapphire crystal case back. This movement operates at a frequency of 4 Hz (28,800 vibrations per hour) and provides a power reserve of approximately 50 hours. The complication is strictly time-only, displaying hours, minutes, and a small running seconds sub-dial, adhering to a traditional and clean layout. The movement’s bridges and mainplate have been treated with a sky blue coating that matches the ceramic case, a detail that demonstrates a high level of finishing and integration between the external design and the internal caliber.

This specific reference 456.EX.5120.EX is in new, mint condition with no signs of wear on the case, crystal, or ceramic bracelet. It is supplied with its full set of accessories and an e-warranty, which is Hublot’s current standard documentation for new timepieces. Within the collector’s market, Hublot’s ceramic models, particularly those in unique colors like this sky blue execution, have established a strong position due to their limited production numbers and technical execution. The Integrated Time Only collection represents a more classically proportioned and versatile offering within the broader Big Bang family, making it a watch with enduring appeal for collectors who value both material innovation and a timeless three-hand design.
