The Seiko SUT318 is an elegant ladies solar-powered watch featuring a luminous white mother-of-pearl dial set with 12 genuine diamond hour markers. The case and bracelet are crafted in two-tone stainless steel combining a yellow gold tone finish with polished and brushed stainless steel, giving the watch a refined, versatile look suited for both everyday wear and formal occasions.

The watch is powered by Seiko's V157 solar movement, which charges via any natural or artificial light source and requires no battery replacement. The 29mm round case is water-resistant to 50 meters (5 ATM), and the dial also includes a date window. The three-link bracelet secures with a fold-over deployment clasp for a comfortable and secure fit.
