Instead, time is presented through ultra-thin sapphire discs, with a large jumping hour aperture at six o’clock delivering exceptional legibility and a dramatic, instantaneous change every hour. The minutes flow continuously along a luminous peripheral track, creating a compelling contrast between precision and motion. At the center, a smoked black sapphire cabochon replaces the dial, acting as a translucent veil that subtly reveals the underlying mechanics while shifting between reflective, opaque, and transparent tones depending on the light. This innovative layout transforms the watch into a modern statement piece, blending avant-garde design with practical readability.\u003cbr\u003e\u003cbr\u003e\u003cspan\u003e\u003cstrong\u003e\u003cem\u003ePre-order now for May 2026 delivery.\u003cbr\u003eA limited edition of 300 pieces.\u003cbr\u003e\u003c\/em\u003eRef.
