Among watch enthusiasts, first impressions often come from the crystal — the interface between the wearer and the movement inside. For our Peacock Black Hole Watch, the crystal is far from ordinary; it is a custom dome-shaped sapphire crystal that elevates the watch to a new level of sophistication and engineering.
A Custom, Integrated Crystal
Unlike conventional flat or slightly curved round crystals, the Black Hole’s dome-shaped crystal is box-shaped and three-dimensional, made as a single, integrated piece. If you look closely, you’ll notice it is actually one continuous, custom-made piece — not two separate components stacked together.

The technical challenge here is significant. Unlike standard round crystals, which are easier to manufacture and install, a dome-shaped, integrated sapphire requires extreme precision in both shaping and polishing. Every curve, edge, and facet must meet exacting tolerances to maintain transparency, avoid distortion, and ensure a perfect visual harmony with the case.
Surface Treatments for Function and Beauty
The surface of the crystal is treated with an anti-fingerprint coating, while the underside features an anti-glare coating. These treatments enhance both clarity and visual depth, creating a layered effect that draws the eye into the intricate movement below. The result is a watch that is not only technically impressive but also visually captivating, with a presence that changes dynamically as light moves across the crystal.
Why This Design Matters

The design intention behind this crystal is to create depth, dimensionality, and a sense of layering. Imagine if we had used a conventional flat round crystal — while functional, it would lack the visual drama and sculptural elegance that the dome-shaped sapphire provides. The Black Hole’s crystal allows the watch to truly stand out on the wrist, giving a dynamic, almost three-dimensional viewing experience that ordinary designs simply cannot achieve.
Comparison with Classic Watches
Traditional luxury watches often use flat or slightly domed crystals. While these are elegant and functional, they rarely push the boundaries of manufacturing complexity. The Peacock Black Hole’s dome-shaped sapphire represents a breakthrough in both aesthetic and technical design. Its integrated, box-shaped form and the dual coatings are a testament to the brand’s commitment to high-end watchmaking and originality.
Community Recognition
Recently, we noticed that collectors and enthusiasts on Watchuseek — one of the world’s most respected watch forums — have been discussing the Black Hole’s crystal. One comment stood out:
“How that crystal covers the case seems pretty unique.”
This feedback echoes what we intended: to design a watch that combines technical mastery with aesthetic innovation, creating a piece that excites both collectors and connoisseurs.
Conclusion

Both the first (sold out) and second generations of the Peacock Black Hole series use the same custom dome-shaped sapphire crystal, reinforcing our dedication to precision, originality, and high-end craftsmanship. In a watch industry often dominated by conventional designs, the Black Hole stands as a bold statement — a fusion of engineering excellence, visual artistry, and uncompromising innovation.
For collectors seeking original, breakthrough timepieces, the Black Hole Tourbillon is more than a watch — it is a celebration of what modern horology can achieve.
