Seiko 5 Sports - SRPK91

Light, bright and full of vintage spirit, the Seiko 5 Sports SNXS Series (ref. SRPK91) dresses the fan-favorite SNXS design in an ivory-tone sunray dial that gives the compact case a soft, warm character. An orange seconds hand, a color found on many Seiko 5 Sports watches in the 1970s, adds a lively accent, while its multi-faceted hour and minute hands catch the light with real presence. Diamond-cut indices with grooved tops sit within a metallic minute track, with LumiBrite on the indices and hands and a day/date calendar for daily convenience.

Behind the dial, the self-winding caliber 4R36 offers 24 jewels, 21,600 vibrations per hour, approximately 41 hours of power reserve and hand winding, all visible through a screw-down see-through case back. The 37.4mm stainless steel case pairs hairline and mirror finishes with a low center of gravity, and its small 4 o'clock crown is positioned so it never breaks the case's flowing silhouette. Protected by a curved Hardlex crystal and water resistant to 100 meters, it closes on a three-fold push-button clasp, making a crisp, versatile pick from weekday mornings to weekend plans.

Timepiece History

Seiko's story began in 1881, when a 21-year-old entrepreneur, Kintaro Hattori, opened a shop selling and repairing watches and clocks in central Tokyo. 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 SRPK91 belongs to Seiko 5 Sports, a collection rooted in the Seiko Sportsmatic 5 of 1963, Japan's first automatic day-date watch. Seiko 5 Sports itself was born in 1968, adding enhanced water resistance, a strengthened crystal and luminous hands and markers to the Seiko 5 essentials of an automatic movement, a day-date display, water resistance, a recessed crown and a durable case and bracelet, and it found worldwide favor as a go-anywhere watch. In 2019, Seiko 5 Sports was rebranded to carry watch culture forward to the next generation. It belongs to the SNXS series, made for everyday life in the city.
