Hublot Spirit of Big Bang Green Saxem 42mm 642.JG.0190.RT

The Hublot Spirit of Big Bang is the tonneau-shaped evolution of the iconic Big Bang family, reimagining the round Big Bang silhouette as a barrel-form case that draws on the heritage of Hublot's earliest designs from the 1980s. Where the original Big Bang announced Hublot's Art of Fusion philosophy to the world, the Spirit of Big Bang refines it — tightening the proportions, softening the angularity, and creating a case architecture that wears with surprising comfort despite its architectural boldness. Reference 642.JG.0190.RT represents one of the most visually dramatic expressions of this line.

At the heart of this reference is the case material: Saxem. Saxem is Hublot's proprietary compound that fuses sapphire crystal with rare-earth elements to produce a material of extraordinary hardness, scratch resistance, and optical clarity. In the green variant, the result is a luminous, translucent emerald hue that transmits light in a way no conventional ceramic or metal can replicate. The 42mm footprint strikes a versatile balance — substantial enough to command attention, yet measured enough to suit a wide range of wrist sizes.

The stainless steel domed bezel frames the Saxem case with a classic Hublot design cue: the H-shaped screws that border the bezel have become as recognizable a brand signature as any crown or crown guard in horology. The domed profile of the bezel adds dimension and depth to the profile view, reinforcing the sense of layered construction that defines the Big Bang family. Every surface transition on this watch is intentional and purposeful.

The rubber strap is another pillar of Hublot's identity. Long before rubber straps became fashionable in luxury watchmaking, Hublot pioneered the combination of precious materials with natural rubber, and today that pairing remains the brand's most characteristic design choice. On the Spirit of Big Bang Green Saxem, the strap grounds the exotic case material in a sporting, wearable context — making 642.JG.0190.RT as comfortable during an active day as it is eye-catching at an evening event.

Owning a Hublot Spirit of Big Bang in green Saxem is owning one of the most technically ambitious watches in contemporary luxury horology. The material science alone places this reference in rare company, and the 42mm sizing ensures it remains a wearable conversation piece rather than a purely collectible object.
