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 change horology history forever.\u003c\/p\u003e\n\u003cp\u003eHere we have an all-time favourite Seiko Linen Dial Quartz, Model 7121-8000. This watch has a dial that is a re-edition of the Seiko Lord Marvel Gold Linen with Arabic numerals and sword hands.\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 10 April 2026. It should be able to operate unhindered until the next battery replacement thereby providing the owner peace of mind. The crown was uncorked to preserve the battery.\u003c\/p\u003e\n\u003cp\u003eIts gold case was also given a good rub while maintaining its sharp lines and sexy curves. Many imperfections were removed without compromising the case shape. There are tarnishing effect imperfections on the bezel though. The selling price has been adjusted accordingly due to this imperfection.\u003c\/p\u003e\n\u003cp\u003eThe crystal was replaced and is now in mint condition.\u003c\/p\u003e\n\u003cp\u003eThe crown is located at its traditional 3H position and is easily accessible. \u003c\/p\u003e\n\u003cp\u003eThe case width and height are approximately 35mm (without crown) and 41mm respectively. The lug width is 19mm and the bracelet can accommodate wrists up to 16.7cm; hence, the watch size is suitable for men and the modern women.\u003c\/p\u003e\n\u003cp\u003eA Bambi brand 2-tone vintage SS bracelet is provided as part of the deal. It too has undergone a thorough cleaning via ultrasonic immersion and buffed.\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 September 1979!\u003c\/p\u003e\n\u003cp\u003eThis is a very classy Seiko Dress Quartz timepiece in stunning condition; so, be unique and own a February 1981 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":43361537294425,"sku":null,"price":110.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0279\/7590\/9465\/files\/IMG20260411151048.jpg?v=1780067457","url":"https:\/\/shop.altimate.sg\/products\/birthday-watch-september-1979-seiko-7121-8000-daini-linen-dial-quartz-watch-oh","provider":"Altimate Group","version":"1.0","type":"link"}
