The 6619 is Seiko's first ever timepiece to have a quickset date via pushing the Crown in.\u003c\/p\u003e\n\u003cp\u003eFor Seiko Collectors and Vintage fans, this is an almost non-existent PRE-SUWA (logo) Dolphin in stunning condition.\u003c\/p\u003e\n\u003cp\u003eThis seldom seen November 1966 Vintage Seiko has a beautiful and immaculately preserved silver sunburst dial that was given a good clean-up. The 3D-styled white-gold-filled Baton Indices, Dauphine Hands, Date Window and silver Chapter Ring are in superb condition after undergoing a good clean-up as well.\u003c\/p\u003e\n\u003cp\u003eIts chromed silver case was buffed as best as possible albeit a few minor scratches that are barely noticeable to the naked eye.\u003c\/p\u003e\n\u003cp\u003eThe crystal was given a good rub and is almost spotless as well.\u003c\/p\u003e\n\u003cp\u003eThe crown is located at the traditional 4H position and is nicely tucked away to prevent damage or snags. The day \/ date quickset works as it should by pushing the crown in to adjust the date and uncorking the crown to adjust the time. The day quickset is something quite unique to this movement \/ model. The day quickset is via turning the hands backwards and forwards past midnight. A tutorial video concerning the day change can easily be found on YouTube.\u003c\/p\u003e\n\u003cp\u003eThe movement was carefully stripped, cleaned, oiled, and re-assembled with general calibration on 28 April 2026. In short, it was given a proper servicing and should be able to operate unhindered until the next servicing thereby providing the owner peace of mind.\u003c\/p\u003e\n\u003cp\u003eEquipped with the highly prized 6619 movement, it has 21 Jewels and operate at 18,000 BPH. The time-grapher shows excellent readings of +2 seconds and amplitude of 212! Such readings are exceptional even by brand new modern automatic watch standards whereby the accepted tolerance is -20 to +40 seconds a day! This is a testament to the quality, the meticulous care provided over the years, and of course the painstaking calibration conducted. Do note that the calibration was conducted at that moment in time. Results may vary later.\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.\u003c\/p\u003e\n\u003cp\u003eDue to its age, this timepiece has not been water-resistant tested.\u003c\/p\u003e\n\u003cp\u003eThe case width and height are approximately 36.5mm (without crown) and 42.2mm respectively. The lug width is 20mm and the bracelet can accommodate wrists up to 17.5cm; thus, this watch is suitable for men and the modern women.\u003c\/p\u003e\n\u003cp\u003eThe watch also comes with a vintage Seiko Signed Oyster Designed SS Bracelet with silver buckle as part of the deal.\u003c\/p\u003e\n\u003cp\u003eThe pictures provided show the watch in excellent condition, and the movement within squeaky clean and well maintained. It has also been demagnetised to improve parts reliability, minimise wear \u0026amp; tear, and improve accuracy. The only drawback is the lack of documentation and original box. An aftermarket box or purposeful carrying case 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 preserved for the next generation to savour such engineering beauty.\u003c\/p\u003e\n\u003cp\u003eYes, there are many other same \/ similar models in the market, but none as beautifully aged and as well maintained as what you see here. Hence, it is a no-brainer that this one-of-a-kind watch will make an extremely beautiful birthday present for that special someone born in November 1966!\u003c\/p\u003e\n\u003cp\u003eThis watch is valued at S$ 182.00 to S$ 403.00 on eBay from really horrible, to un-serviced, to \"as is,\" to serviced condition. Note: the mentioned prices may \/ do not include currency conversions, commissions, taxes and freight costs etc. \u003c\/p\u003e\n\u003cp\u003eThis fully serviced and calibrated timepiece is being sold here for S$ 299.00 which is extremely reasonable. I have also taken into consideration the minor chippings while determining the selling price. So, NO LOW-BALLERS ND TIME-WASTERS, please! Take note that low-ballers, trolls and wannabe advisors (whose \"advise\" is completely unwelcomed) will not be entertained, and should they persist, they will be reported and blocked! \u003c\/p\u003e\n\u003cp\u003eDo also bear in mind that it will cost between S$ 180.00 to S$ 200.00 for a proper overhaul, an estimated S$ 80.00 to calibrate (depending on watch condition), and S$ 100.00 to clean and polish including tightening of bracelet links - these costs do not apply when purchasing this timepiece. So, if anyone was to sell such a timepiece at a low price yet claim that it has been serviced, one has to ask what kind of servicing was conducted, if any.\u003c\/p\u003e\n\u003cp\u003eThis is a highly sort-after November 1965 Seiko 5 Sportsmatic 6619-9000 AD JDM Automatic Timepiece; so, be unique and own a November 1965 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":43361731870809,"sku":null,"price":299.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0279\/7590\/9465\/files\/IMG20260501142449.jpg?v=1780077194","url":"https:\/\/shop.altimate.sg\/products\/birthday-watch-november-1966-seiko-5-6619-8120-sportsmatic-21j-automatic-watch-oh","provider":"Altimate Group","version":"1.0","type":"link"}
