The Seiko Tressia SUP325 is an elegant ladies' dress watch featuring a two-tone stainless steel case and bracelet in silver-tone and gold-tone finishes. The fixed bezel is set with 24 genuine diamonds, surrounding a luminous mother-of-pearl dial with gold-tone hands and dot hour markers, and index markers at the 6 and 12 o'clock positions.

Powered by Seiko's caliber V115 solar movement, the watch converts light into energy and requires no battery replacement. The oval stainless steel case measures 25mm in diameter and 7mm thick, with a 9mm band width and fold-over clasp. The scratch-resistant Hardlex crystal protects the dial, and the watch is water resistant to 30 meters (100 feet). Movement is Japan-made quartz.
