The Seiko 5 Sports SRPK31 brings vintage-inspired dive-watch styling to a compact and versatile 38mm format. Inspired by the iconic Seiko quartz divers of the 1980s, this mid-size model features an elegant ivory sunray dial framed by a dark gray unidirectional rotating bezel, creating a distinctive retro-sport aesthetic. Powered by the reliable Seiko Caliber 4R36 automatic movement, the SRPK31 features 24 jewels, a frequency of 21,600 vibrations per hour, approximately 41 hours of power reserve, and manual winding capability. The practical day/date calendar and luminous hands and markers provide everyday functionality and excellent readability. The 38mm stainless steel case measures just 12.1mm thick and is paired with a comfortable three-row sport bracelet. A screw-down see-through caseback offers a view of the automatic movement, while the tri-fold push-button clasp with secure lock ensures a dependable fit. With 100m water resistance, the Seiko 5 Sports SRPK31 is a stylish everyday mechanical watch with a strong vintage character.
