Vintage SEIKO TYPE II 8223-8090 SGP Gold, Silver Face, Men's Quartz Wristwatch, New Battery, St. Steel Metal Band, Excellent Working Condition The "SEIKO TYPE II [8223-8090] " is a vintage quartz men's wristwatch manufactured by Suwa Seikosha 諏訪精工舎in the late 1970s. It is part of the "TYPE II" series, which Seiko developed to popularize quartz technology for the public. Historically, the TYPE II series was developed as a mid-range model during Seiko's transition from high-end quartz to more affordable models in the 1970s. Seiko revolutionized the global wristwatch market with the "Quartz Revolution" of the 1970s. After introducing the world's first mass-produced quartz wristwatch, the "Quartz Astron," in 1969, Seiko expanded its technology from its high-end "Quartz" line to the mid-range and popular price ranges, offering a wide range of models that combined reliability and practicality. The Type II series, positioned as the core of this trend from the late 1970s to the early 1980s, was a series focused on balancing precision, durability, and cost for everyday use. It bridged the gap between high-end models (Grand Quartz, King Quartz) and popular models (SQ, etc.) and was embraced as a "Seiko-like, realistic solution." Type II Series Positioning and Features： • Practical Design: Avoiding excessive ornamentation, emphasizing legibility and comfort. The excellent contrast of the indices and hands makes it suitable for both business and casual wear. • Stable Movement: Equipped with a quartz caliber that Seiko had perfected through mass production at the time, its annual accuracy is in a range that is satisfactory for everyday use. Designed for durability: Basic waterproof and dustproof performance is maintained, and the case and bracelet are also very sturdy. Repair parts are also relatively readily available （compatible parts）. • Balanced price range: While it lacks the special features of the luxury line, it embodies "Seiko's standard quality" in terms of finish and reliability. Its cost performance is highly rated in the used market as well. • The appeal of this model "Seiko's rationality": While not flashy, it provides sufficient precision and reliability for daily timekeeping. • An entry point to vintage: An affordable price range that allows you to experience the design philosophy of the golden age of Japanese quartz watches. • Aesthetics with a sense of the times: The sharp design created by the transition between straight lines and surfaces, and the restrained dial layout suit current styles. At the time, these watches manufactured by Suwa Seikosha, they boast high accuracy （±15 seconds per month） and are renowned for their reliable movements.　Combining design and practicality, these watches feature attention to detail, such as the color-coded day of the week display (Saturday: blue, Sunday: red). They are highly sought-after on the pre-owned market, fetching high prices depending on their condition.　This watch truly symbolizes a turning point in Seiko's history, created to bring the "quartz revolution" to the masses. Quietly ticking away, this timepiece conveys the technology and aesthetic sensibilities of the time.
