Quartz watches use a quartz crystal oscillator to keep time, which is much more accurate than the 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 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 change horology history forever.\u003c\/p\u003e\n\u003cp\u003eHere we have an October 1980 Seiko Silverwave Dress Quartz, Model 8229-8000 in stunning condition.\u003c\/p\u003e\n\u003cp\u003eThis timepiece was carefully stripped and underwent a good servicing, and its dial was meticulously cleaned, its electronic movement cleaned, touched up, demagnetised and battery replacement on 20 May 2026. \u003c\/p\u003e\n\u003cp\u003eIts well-preserved case was also given a good clean-up and rub while maintaining its sharp lines and sexy curves. Most imperfections were removed without compromising the case shape. The crystal was replaced and was given a good rub and is now in mint condition.\u003c\/p\u003e\n\u003cp\u003eThe crown is located at its traditional 3H position and is easily accessible. The crown is left uncorked to prevent battery drainage.\u003c\/p\u003e\n\u003cp\u003eThe case width and height are approximately 36.9m (without crown) and 40.9mm respectively. The lug width is 18mm and the bracelet can accommodate wrists up to 20cm; hence, this watch is suitable for men and the modern women.\u003c\/p\u003e\n\u003cp\u003eA Seiko Signed President Designed SS Bracelet comes with the watch as part of the deal. It too was given a good cleaning and polish and is now in excellent condition albeit miniscule scratches do remain.\u003c\/p\u003e\n\u003cp\u003eThe watch is 100% original Seiko components from this particular watch. No parts were replaced with aftermarket parts.\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 show the watch in excellent 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 one-of-a-kind timepiece will make an extremely beautiful birthday present for that special someone born in October 1980!\u003c\/p\u003e\n\u003cp\u003eThis particular classy Seiko Silverwave Dress Quartz timepiece is rather rare and can only be found in Japan it seems.\u003c\/p\u003e\n\u003cp\u003eThis is a very classy Seiko Sporty Quartz timepiece in excellent condition; so, be unique and own an October 1980 Birthday Watch that is almost impossible to source in such fine condition or purchase it for that special someone instead.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Altimate Group","offers":[{"title":"Default Title","offer_id":43362108670041,"sku":null,"price":222.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0279\/7590\/9465\/files\/IMG20260523153922.jpg?v=1780086157","url":"https:\/\/shop.altimate.sg\/products\/birthday-watch-october-1980-seiko-silverwave-8229-8000-jdm-quartz-watch-oh","provider":"Altimate Group","version":"1.0","type":"link"}
