Description
The design draws inspiration from the event horizon—the mysterious boundary surrounding a black hole from which even light cannot escape. As matter is pulled inward by immense gravitational forces, it forms a blazing accretion disk, radiating extraordinary energy and light.
The hands are derived from the geometric aesthetics of the black hole's "external gravitational field." Hand-finished hands and the inner dial ring, combined with hand-applied titanium flame coloring, capture fleeting blue-purple hues at temperatures between 550°C and 600°C—symbolizing the energy release of the black hole's accretion disk. As a result, every piece exhibits unique color patterns.
This watch is fitted with a central tourbillon movement, integrating 196 components within a 35.6 mm diameter. The titanium tourbillon cage weighs just 0.46 grams. Four mainspring barrels connected in series deliver a 120‑hour power reserve. The bottom plate bridges and textures perfectly recreate the visual effect of a black hole's vortex.
The vortex motif is embodied by an eight-segment guilloche, entirely hand-engraved. Crafted with a 3° rotation angle, over 400 cutting strokes and a precise line spacing of 0.3125 mm, the engraved lines intersect tightly yet never cross the boundary. A single error during the process renders the entire dial unusable.
The case and buckle are forged from Grade 5 titanium, renowned for its exceptional strength, lightness, and corrosion resistance. A domed sapphire crystal integrates seamlessly with the case, while a fluoro rubber strap enhances wearing comfort.
Supplied by the brand to the GPHG for its entry.
