Standing out like a futuristic starship in space, the Grand Central Tourbillon Flash features a redesigned dial, on which the House’s distinctive numerals are replaced by bright, vibrantly coloured indices on a microblasted black matte dial, all pointing toward the centre of the timepiece, highlighting the mesmerising mechanics of the tourbillon. The tourbillon’s cage bridge also incorporates a striking neon arrow, rotating around the nucleus like an electron, enabling the seconds to be read.

Housed in the redesigned Curvex CX case which debuted in 2021, the movement of the Grand Central Tourbillon Flash is fitted to the curved case middle. Affording greater visibility of the flashy indices and spellbinding centre tourbillon, the sapphire crystal extends all the way to the lugs—a feat achieved only after perfecting a special technique of fixing the glass at 12 o’clock and 6 o’clock—and giving the Curvex CX our most curved profile to date.
