The Seiko Coutura SUT240 is an elegant solar-powered ladies' watch featuring a luminous mother of pearl dial adorned with 24 genuine diamonds. Part of Seiko's Coutura collection, this timepiece combines refined style with practical solar technology, drawing power from both natural and artificial light sources with a power reserve of approximately six months once fully charged.

The watch is crafted with a two-tone stainless steel case and matching bracelet in polished silver and gold-tone finishes. A sapphire crystal protects the dial, which displays the time with classic stick indexes and a date window at the 3 o'clock position. The case measures approximately 27–29mm, making it a refined fit for everyday wear. The cabochon crown adds a decorative touch consistent with the collection's dressy aesthetic.

Powered by Seiko's Caliber V137 solar movement, this watch offers 100 meters (330 feet) of water resistance and arrives with its original box and packaging.
