The 36 gemstones, chosen for their optimal color gradient transition based on the original factory design, are meticulously crafted with consistent height and angle for a beautiful refraction effect. Each sub-dials on the dial refracts light differently, resulting in vibrant and bright colors. It features a fully automatic mechanical movement, a solid 316L stainless steel three-link easy-adjustable bracelet, and a 40mm x 13mm mineral crystal with exquisite and meticulous polishing.
