It was circa 1964 that Seiko began officially re-naming their 3-digit models into 4 digits. It did not occur overnight but was a gradual process due to the number of existing \/ operating calibers.\u003c\/p\u003e\n\u003cp\u003eOriginally meant for the Japanese Domestic Market, this almost non-existent timepiece is a highly sort-after Collectible.\u003c\/p\u003e\n\u003cp\u003eFor Seiko Collectors and Vintage fans, this is a Seiko 860 Champion Calendar Seikosha DAINI (without the logo) in near-mint condition.\u003c\/p\u003e\n\u003cp\u003eIts timeless shaped silver case, white-gold hands and indices are in stunning condition and had undergone a painstaking cleaning process and almost all imperfection have been meticulously removed. There may be a few minor scratches and age marks remaining on the case but are barely noticeable.\u003c\/p\u003e\n\u003cp\u003eIts original sunburst gunmetal grey dial is in immaculate status after a good clean-up. The dial gives off a vintage-like reflections at certain angles and light conditions. The crystal was replaced with a hi-end crystal and polished.\u003c\/p\u003e\n\u003cp\u003eThe crown is original and located at the 3H position and is neither too big nor too small to handle. The date and hands operate in the traditional manner by uncorking and rotating the crown that works as it should.\u003c\/p\u003e\n\u003cp\u003eThe movement was carefully stripped and meticulously cleaned via ultrasonic immersion, oiled, re-assembled and calibrated on 15 August 2023. In short, it underwent an overhaul and not a basic service 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 classic 860 \/ 7622 movement, it has 17 Jewels that operate at 18,000 BPH. The time-grapher shows excellent readings of +7 seconds and amplitude of 253! Such readings are almost impossible even for 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 expert and painstaking calibration done.\u003c\/p\u003e\n\u003cp\u003eThe watch comes with a brand-new Time King high-quality Black genuine leather strap with silver buckle which is pure class as part of the deal.\u003c\/p\u003e\n\u003cp\u003eThe case width and height are approximately 36.5m (without crown) and 44.2mm respectively. The lug width is 19mm and the genuine leather strap can accommodate wrists up to 21.0cm; hence, this watch is suitable for men and the modern women.\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\u003eDue to its age, this timepiece has not been water-resistant tested.\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 + 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 \/ similar models in the market, but none has 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 December 1964.\u003c\/p\u003e\n\u003cp\u003eThis is a highly sort-after Seiko 860AD \/ 7622 Champion Calendar watch; so, be unique and own a December 1964 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":44258769993817,"sku":null,"price":477.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0279\/7590\/9465\/files\/IMG20260730180111.jpg?v=1785451606","url":"https:\/\/shop.altimate.sg\/products\/birthday-watch-december-1964-seiko-champion-calendar-860-7622-8980-daini-jdm-17j-mechanical-watch-oh","provider":"Altimate Group","version":"1.0","type":"link"}
