HYDROCORE GEMSTONES WATCH

Its stainless steel case and bracelet establish a solid, architectural base, while the bezel—set with alternating red and white gemstones—creates a vivid outer ring that captures and refracts light with striking clarity. The dial is defined by a layered roulette-inspired composition, where concentric rings of color and numerals generate a sense of motion and depth. Rich tones of red, green, and warm brown radiate outward from the center, forming a dynamic visual rhythm against the darker backdrop.
