Quartz watches use a quartz crystal oscillator to keep time that is much more accurate than traditional mechanical movements used in wristwatches at the time.\u003c\/p\u003e\n\u003cp\u003eThe quartz movement in the Astron was incredibly precise, with an accuracy of within 5 seconds per month, far superior to mechanical watches of the era.\u003c\/p\u003e\n\u003cp\u003eThe introduction of the Seiko Quartz Astron had a profound impact on the watch industry. It marked the beginning of the Quartz Revolution that led to the decline of traditional mechanical watches in the market and the rise of more accurate and later, more affordable quartz timepieces.\u003c\/p\u003e\n\u003cp\u003eSeiko's Quartz Astron was showcased at the Baselworld watch fair in Switzerland in 1970, where it received international attention and acclaim because this watch changed horology history forever.\u003c\/p\u003e\n\u003cp\u003eHere we have a very well-preserved June 1979 JDM Seiko Type II 7123-8100 DAINI Quartz Dress Watch with Linen Dial in stunning condition.\u003c\/p\u003e\n\u003cp\u003eSeiko introduced the Type II quartz series circa 1976 as a supposed entry level quartz movement, but its quality had surpassed its price range, thus the market responded and made the Type II series the Seiko watch to own reminiscent of the Casio G-Shock craze of the 90s. Better Type II were thence produced thus improving overall quality and prestige to this range.\u003c\/p\u003e\n\u003cp\u003eThis timepiece was given a good servicing, and its dial was meticulously cleaned, its electronic movement cleaned and touched up, demagnetised, and its battery replaced on 17 November 2025. It should be able to operate unhindered until the next battery replacement thereby providing the owner peace of mind.\u003c\/p\u003e\n\u003cp\u003eIts stylish silver case was also given a good clean-up while maintaining its sharp lines and sexy curves. Many imperfections were removed albeit a few scratches synonymous with age remains. The crystal was replaced and given a good buff.\u003c\/p\u003e\n\u003cp\u003eThe crown is located at its traditional 3H position and is nicely tucked away to prevent damage and snags yet easily accessible. The day\/date and time quick adjustment is via uncorking the crown to the first level and second level to adjust respectively.\u003c\/p\u003e\n\u003cp\u003eBecause it is a JDM model, the day is in English and Kanji. Cool!\u003c\/p\u003e\n\u003cp\u003eThe case width and height are approximately 35.9mm (with crown) and 40.5mm respectively. The lug width is 18mm and the bracelet can accommodate wrists up to 16.5cm; hence, the watch size is suitable for men and modern women.\u003c\/p\u003e\n\u003cp\u003eThe SS bracelet is a vintage Seiko Signed Oyster model. It too was given a good clean-up via ultrasonic immersion followed by a good buff and is now in near mint condition albeit minor scratches on the buckle synonymous with age.\u003c\/p\u003e\n\u003cp\u003eTo the best of our knowledge and expertise when overhauling the timepiece, the watch is 100% original Seiko components from this particular watch. No parts were replaced with aftermarket parts or modified thereby it is considered in near mint condition.\u003c\/p\u003e\n\u003cp\u003eThis timepiece has not been water-resistant tested due to its age.\u003c\/p\u003e\n\u003cp\u003eThe pictures provided shows the watch in near mint condition and well maintained. It has also been demagnetised to improve parts reliability, minimise wear + tear, and improve accuracy. The only drawback is the lack of documentation and original box. A nice purposeful carrying case or box will be provided instead.\u003c\/p\u003e\n\u003cp\u003eBear in mind that this watch has seen many of the previous owners’ ups and downs in life and should be cherished and well taken care of for the next generation to savour such engineering beauty.\u003c\/p\u003e\n\u003cp\u003eYes, there are many other same models in the market, but almost all are not in the same quality condition and as well maintained as what you see here. Hence, it is a no-brainer that this very rare timepiece will make an extremely beautiful birthday present for that special someone born in June 1979!\u003c\/p\u003e\n\u003cp\u003eThis is a very lovely Seiko Dress Watch in stunning condition; so, be unique and wear a rare June 1979 Birthday Watch that is almost impossible to source or purchase it for that special someone.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Altimate Group","offers":[{"title":"Default Title","offer_id":43416510169177,"sku":null,"price":255.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0279\/7590\/9465\/files\/IMG20260609093221.jpg?v=1781030461","url":"https:\/\/shop.altimate.sg\/products\/birthday-watch-june-1979-seiko-7123-8100-type-ii-linen-daini-jdm-quartz-watch-oh","provider":"Altimate Group","version":"1.0","type":"link"}
