Brand: Seiko Model: 5 Sports Reference Number: 7019-6010 Serial Number: 053449 Movement: Automatic Caliber 7019A Dial: Deep black dial with applied indices, featuring heavily textured aged luminous material and a clean background Case Size: 40 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1970 Condition: Good vintage condition with honest wear and distinct patina on the hands and markers Dial and Hands The dial presents a deep, matte black background that remains impressively clean and well-preserved. It is appointed with applied silver-tone baton indices that house heavily textured, aged, and visually degraded white luminous material, showcasing a distinct and honest vintage patina. The silver-tone baton hour and minute hands exhibit a matching heavily textured luminous infill, while the sweeping center seconds hand provides a vibrant pop of contrasting orange. The typography is crisp, featuring the applied Seiko 5 shield, the word "SPORTS" printed in a striking light blue, and the highly desirable "WATER 70m PROOF" designation printed in white just above the Suwa factory symbol. A framed aperture at the three o'clock position displays the day and date, featuring a dual-language English and Kanji day wheel. The dial is framed by a black internal rotating bezel ring with silver numerals, which shows mild age-consistent fading. Case and Crystal The 40 millimeter stainless steel cushion case is a classic representation of the era, featuring a hidden lug design that provides a substantial presence on the wrist. The upper surface of the case displays distinct radial brushing that sweeps outward from the dial, creating a sharp and attractive transition to the highly polished case flanks. A recessed crown is neatly positioned at the four o'clock mark, maintaining the seamless silhouette of the case. The watch is fitted with a domed crystal that protects the dial and enhances the vintage profile. The case exhibits honest signs of wear, including superficial scratches, minor scuffs, and light handling marks consistent with a sporting watch of this age, yet it retains its strong factory geometry and sharp lines. The screw-down caseback is well-preserved, clearly displaying the Seiko Suwa emblem, the reference number 7019-6010, the serial number, and the original "WATERPROOF" engraving.

The movement remains fully operational. Dimensions Case Size: 40 mm Remarks The "Water 70m Proof" designation on the dial is a highly sought-after detail among vintage Seiko enthusiasts, marking this piece as an early production model manufactured just before the industry-wide regulatory shift to "Resist" marked dials. The combination of the Kanji day wheel, the vibrant orange seconds hand, and the internal rotating bezel adds immense character to this robust sports watch, making it a versatile and historically interesting addition to any collection. History The Seiko 5 Sports line was introduced in the late 1960s to offer robust, water-resistant, and visually dynamic timepieces designed specifically for a younger, more active generation. Built upon the five foundational attributes of the original Seiko 5 series, including an automatic movement, day-date display, and water resistance, the Sports line pushed the boundaries of case design and dial aesthetics. These watches quickly became a cornerstone of Seiko's global success, prized for their durability and striking, unconventional looks. The cushion-cased models of the early 1970s remain iconic representations of the era's bold horological design language. Payment and Shipping Payment must be completed within 1–3 days after purchase.
