In the early 1970s, Seiko was fully committed to producing reliable mechanical sports watches for everyday use. This Seiko 5 Sports is a clear product of that era — a watch designed not for luxury display, but for durability, readability, and real-world practicality. The stainless steel cushion-shaped case gives this model its strong presence. Rounded yet substantial, it reflects the unmistakable design language of Seiko sports watches from the period. With a case diameter of approximately 39 mm, it offers a well-balanced size that wears comfortably even by modern standards, while still retaining its vintage character. The blue dial is one of the highlights of this watch. Its vivid tone, combined with bold applied hour markers, ensures excellent legibility. The markings “SPORTS” and “WATER 70m PROOF” clearly indicate that this is not a dress watch, but a purpose-built sports model intended for daily wear. Inside is Seiko’s automatic Caliber 7019 series movement, a robust and proven workhorse of the time. It features both day and date displays with practical operation: Day can be changed by pushing the crown (English / Japanese bilingual wheel) Date can be adjusted by pulling the crown to the first position Time setting is done by pulling the crown to the second position This movement reflects Seiko’s focus on usability and reliability during the mechanical era. Based on the case-back engraving, this watch dates to the early 1970s. It represents the period when the Seiko 5 Sports line gained worldwide recognition as a dependable mechanical watch for everyday life. A new leather strap has been installed, providing a clean appearance and comfortable wear while preserving the vintage aesthetic. At the time of listing, the watch is running. As a vintage item, stable long-term operation, accuracy, and water resistance are not guaranteed. The watch will be carefully packed and shipped with tracking to ensure safe delivery. This is a genuine example of Seiko’s 1970s sports watch philosophy — functional, honest, and built to be worn.
