SEIKO 5 Sports SRPK89 Features
Seiko 5 Sports SNXS Series
Continuing the evolution of our long-standing Seiko 5 Sports SNXS series, this new watch adopts the design principles of these original Seiko 5s. Built to fit the theme of classic sports, this watch takes the essence of the 70s Seiko 5 Sports models and integrates them with modern specifications.
Under a semi-spherical glass, the dial features Lumibrite hands and indices, each diamond-cut with finely grooved lines, on a ‘beige chinos’ cream color dial. The hands are non-triangular and are wider, to enhance the vintage retro look whilst the orange second hand is inspired by the classic 70s design. With a metal dial ring, the bracelet features striking mirror and hairline finishing.
This piece is powered by an in-house 4R36 automatic movement, which is accurate to +45 / -35 seconds per day, and has a 40-hour power reserve.
Seiko 5 Sports is known for over fifty years of reliability, durability, performance, and value. ‘’5’’ represents the original five key features of every Seiko 5 still present today: Automatic movement, Day-date display, Water Resistance, Recessed crown and Durable case and bracelet.
Seiko 5 Sports launches a new “SNXS” series that evolves based on its heritage.
Based on Seiko’s world-renowned SNXS sports watch, the new series was developed with the concept of EDC (Everyday Carry), something you carry every day. While retaining the characteristic case shape and the small crown at the 4 o’clock position that doesn’t interfere with the flowing case shape, there are also various improvements, and the series has evolved.
The sporty ivory dial features an orange seconds hand, which was used in many 5 Sports watches in the 1970s. The multi-faceted hour and minute hands reflect light while imparting a strong presence. Lumibrite is applied on the upper surface of the 11 bar indexes and the hour and minute hands.
The case’s low center of gravity ensures a more comfortable fit, and contrasting hairline and mirror finishes contribute to a sense of stylishness while exuding high quality. The newly developed metal bracelet gives a classical impression that is both new and nostalgic.
- Calendar day and date display
- See-through and screw case back

About Seiko 5
Seiko 5. Bold designs that speak volumes about those who dare to wear the Seiko 5. The inspiration lies in the edgy designs and dramatic colours, that come together with an innovative automatic movement that defines the very spirit of a Seiko 5.
From the very start, Seiko 5 was a watch whose performance would serve the demanding needs of the new 1960’s generation, who cared less for tradition and more about life. The watch had five key attributes :
1. Automatic winding
2. Day/date displayed in a single window
3. Water resistance
4. Recessed crown at the 4 o’clock position
5. Durable case and bracelet
The technology behind the legend
From the start, Seiko 5 was designed to break the mold of watch performance and to bring to the young 1960’s generation a watch that belonged to their age and that fitted into their lives. As perhaps never before, young people of the day saw no limits to their aspirations. Seiko 5 needed to be a watch that could go anywhere and everywhere. The first challenge was durability. To be durable, a watch needs to be impervious to two threats; water and shock.
Water resistance was built in as standard to every Seiko 5 watch, and metal bracelets were used so that, from buckle to buckle, the watch was resistant to water and sweat. Shock resistance was assured with two Seiko inventions. First, the mainspring was made from “Diaflex,” an unbreakable alloy, and the “Diashock,” system was created to protect the movement from shock within the case.
Legibility was the next vital attribute. Today, we take for granted that day and date are presented in a single window but, in fact, this was an idea built in to Seiko 5 to enhance the legibility of the dial. The genius create a unique system that allowed both day and date to be shown in one plane.
The final challenge was to create a distinctive look that defined the brand. Thanks to the extraordinary Seiko invention of the ‘Magic Lever,’ the winding efficiency of Seiko 5 is very high, and the wearer rarely needs to use the crown. So the designers made it smaller and hid it under the lip of the case at 4 o’clock, giving Seiko 5 its signature look.
History of Seiko 5
Seiko began producing its Seiko 5 line of automatic watches back in 1963. Since then watch enthusiasts around the world have come to recognize Seiko 5 as reliable, affordable and well respected watches. Over the last 50 years Seiko has produced thousands of different models in the line.
History of Seiko
The company was founded in 1881, when Kintarō Hattori opened a watch and jewerly shop called “K. Hattori” (服部時計店 Hattori Tokeiten) in the Ginza area of Tokyo, Japan. Eleven years later, in 1892, he began to produce clocks under the name Seikosha, meaning roughly “House of Exquisite Workmanship”.
The first watches produced under the Seiko brand appeared in 1924. In 1969, Seiko introduced the Astron, the world’s first production quartz watch, it cost the same as a medium-sized car. Seiko later went on to introduce the first quartz chronograph.
