Available now on auction by Second Vintage This Seiko Sportsmatic 5 is a charming example of mid-century Japanese horology, representing the foundation of the legendary Seiko 5 line. With its classic "Water Proof" dial text, this timepiece predates the industry-wide shift to "Water Resistant" terminology in the early 1970s, making it a desirable collector's piece. The combination of the clean silver sunburst dial and the robust automatic movement makes this a quintessential daily wearer for the vintage enthusiast. Brand: Seiko Model: Sportsmatic 5 Reference Number: 6619-8970 Serial Number: 1D8089 Movement: Automatic Caliber 6619A Dial: Silver sunburst Case Size: 36 mm (excluding the crown) Case Material: Stainless Steel Production Year: c. 1960s Condition: Good vintage condition. The watch presents an honest, original aesthetic with visible signs of wear to the case and light patina on the dial, while timegrapher results confirm the movement is running. Dial and Hands The watch features a classic silver sunburst dial that retains a lovely sheen. It is adorned with polished, faceted block hour indices and the applied Seiko Sportsmatic script and "5" shield logo. A framed day-date window is positioned at 3 o'clock. The dial shows minor signs of aging, including some faint spotting and patina consistent with its age, which adds to its vintage character. The dauphine-style hands are sharp and legible, showing only very minor oxidation. The "Water Proof" text at 6 o'clock is crisp and historically significant. Case and Crystal The 36mm stainless steel case features the distinct architectural lines of the era, with substantial lugs and a hidden crown recessed at the 4 o'clock position, a signature design element of the early Seiko 5 models intended to emphasize the automatic winding system. The case is in good vintage condition, showing surface scratches and handling marks commensurate with decades of use. The screw-down caseback retains its engravings, including the reference and serial numbers. The crystal is clear and presents well, offering an unobstructed view of the dial. Movement Powering this timepiece is the robust Seiko Caliber 6619A, a 21-jewel automatic movement known for its reliability. The movement features the practical "Seiko push" date quickset function, operated by pressing the crown inward. Timegrapher testing indicates a daily rate of approximately +57 to +66 seconds per day. This indicates a running movement that is operating and running. Strap The watch is fitted with a brand new, deep blue leather strap with an alligator grain pattern. The dark blue tone provides a sophisticated contrast against the silver dial and steel case, elevating the watch's dress appeal while ensuring a comfortable fit on the wrist. Condition This timepiece is in good vintage condition. It wears its history honestly, with case wear that adds character without detracting from the overall form. The dial remains attractive and the movement is functional. It is a genuine example of a 1960s daily driver that has survived in presentable and wearable form. Dimensions With a diameter of 36mm excluding the crown, the watch sits comfortably on a variety of wrist sizes. The vintage proportions allow it to slide easily under a shirt cuff while still maintaining a presence due to the case thickness and lug design. Remarks The presence of "Water Proof" on the dial and caseback is a specific detail sought after by Seiko collectors, as it dates the watch to the era before strictly enforced nomenclature changes in roughly 1970. Inside the caseback, hand-written Japanese service marks are visible, adding a layer of authentic provenance to this domestic market timepiece. History Introduced in 1963, the Seiko 5 set a new standard for affordable, durable, and reliable mechanical watches. The "5" stood for five key attributes: automatic winding, day/date display, water resistance, a recessed crown, and a durable case and bracelet. The Sportsmatic line was instrumental in establishing Seiko's dominance in the global watch market, offering robust engineering that has allowed these watches to keep running more than half a century later. / Second Vintage SKU: SEI-SSW-0003
