Charming and easy to read, the Seiko Essentials (ref. SUR438) is a ladies' quartz watch we love for its cheerful mix of classic style and everyday practicality. Stylized Arabic numerals give the white dial a friendly, legible character, and a day-date window keeps the calendar in view. The petite 25.5mm case and matching bracelet come in two-tone stainless steel, a versatile finish that pairs easily with the jewelry already in your collection.

At 8.57mm thick with a 13mm lug width, the case has a delicate presence on the wrist, while a Hardlex crystal protects the dial. Water resistance to 100 meters is a welcome bonus in a watch this dainty, making it an easy everyday favorite. Features Stylized Arabic numerals – a clear, friendly look on the white dial.

The first watch to carry the Seiko name followed in 1924, and Seiko went on to introduce a long line of watchmaking firsts, including the Quartz Astron, the world's first quartz wristwatch, on December 25, 1969. In 2024, Seiko celebrated the 100th anniversary of the Seiko brand. The SUR438 is part of Seiko Essentials, a collection that pairs classic and contemporary design with dependable performance, made to keep you stylish and on time on any occasion.
