A peripheral wave-pattern ring seems to rotate endlessly, its subtle undulation amplified by the domed sapphire crystal.
At the heart of this extraordinary timepiece lies a flawless black enamel dial—deep, glossy, and utterly captivating, like polished onyx reflecting infinite night.
A slender 18K gold ring encircles this void, subtly framing the “core order of time” with understated luxury. Precision-cut diamond-shaped hour markers rise from the surface, their multi-faceted edges catching light in sharp, crystalline flashes. Against the abyssal black backdrop, these markers create striking contrast—each glance revealing new sparks of brilliance that pierce the darkness.
Beyond this serene center, the design embraces dynamic energy. A peripheral wave-pattern ring appears to rotate endlessly, its gentle undulations magnified by the domed sapphire crystal. Concealed beneath the glass, intricate three-dimensional radial engravings evoke frozen ripples or silent sound waves—adding profound depth and a sense of perpetual motion to the otherwise minimalist black dial.
Powered by our expertly modified Miyota 8215 automatic movement, this watch delivers reliable precision and smooth performance in a slim, versatile profile. The result is more than timekeeping—it’s an immersive exploration of light, shadow, and subtle animation on the wrist.
