Brand: Seiko Model: Sportsmatic 5 Reference Number: 6619-9040 Serial Number: 6N30357 Movement: Automatic Caliber 6619A Dial: Charcoal sunburst with stardust patina Case Size: 39 mm (excluding the crown) Case Material: Stainless steel Production Year: 1966 Condition: Fair vintage condition. The watch shows honest signs of age, particularly the even stardust patina on the dial and visible wear on the case, while running strongly with healthy amplitude. Dial and Hands The dial features a dark charcoal sunburst finish that has aged to display a consistent and distinct "stardust" patina across the surface, giving the watch a unique and galaxy-like character. It is adorned with applied silver block indices and sharp dauphine hands, which show some oxidation consistent with age. A framed day-date window is positioned at 3 o'clock, maintaining the classic Sportsmatic layout and enhancing readability. Case and Crystal The stainless steel case measures a substantial 39mm, offering a modern presence on the wrist that is larger than many contemporaries from this era. It features the signature hidden crown at the 4 o'clock position, a design trait of this specific period intended to emphasize the automatic winding efficiency. The case surfaces show visible scratches and marks consistent with a life of use, but the lug lines remain defined. The caseback displays the desirable embossed dolphin motif, and while it shows wear, the reference and serial numbers remain legible. The acrylic crystal has some fine surface marks but remains clear. Movement Powering the watch is the robust Seiko automatic caliber 6619A, a 21-jewel movement known for its durability and engineering. The movement is clean in appearance and is currently running within vintage tolerances. Timegrapher testing indicates a rate of +15 to +20 seconds per day, suggesting a healthy mechanism for a watch of this vintage. Strap The watch is fitted with a new brown leather strap featuring a crocodile grain pattern and a polished stainless steel pin buckle. The strap complements the dark tones of the dial and is in unworn condition, ready for immediate wear. Condition This timepiece is in fair vintage condition. The primary sign of aging is the heavy spotting or "stardust" patina on the dial, which many collectors find attractive for its unique wabi-sabi aesthetic. The case shows general surface wear, scratches, and nicks expected from a tool watch of the 1960s. The movement is functioning well and the calendar features operate correctly. Dimensions With a case diameter of 39 mm excluding the crown, the watch wears prominently on the wrist. The lug-to-lug length ensures a comfortable fit on various wrist sizes, while the thickness accommodates the automatic rotor without being overly bulky. Remarks This Seiko Sportsmatic 6619-9040 is a testament to the brand's golden era of mechanical watchmaking. The combination of the jumbo case size, the dolphin caseback, and the honest patina makes it a distinctive choice for collectors who appreciate watches with a story. It represents an affordable entry point into the world of vintage Seiko "5" history and offers reliable vintage performance. History The Seiko Sportsmatic line was pivotal in the 1960s, introducing the "5" concept which stood for automatic winding, day/date display, water resistance, recessed crown at 4 o'clock, and a durable case and bracelet. This specific model hails from November 1966, a time when Seiko was rapidly establishing itself as a world-class manufacturer, competing directly with Swiss counterparts in terms of innovation and reliability. / Second Vintage SKU: SEI-SSW-0007
