However, the King Seiko 56KS range was produced by the SUWA factory because it is the same movement as the Grand Seiko 56GS!\u003c\/p\u003e\n\u003cp\u003eThe Seiko 5626 movement made its debut in 1969, the same year Seiko introduced their quartz range to the world due to the insatiable demand for such watches.\u003c\/p\u003e\n\u003cp\u003eThat is why, this is a highly sort-after Collectible because it is a Grand Seiko in disguise! And it is almost non-existent because Seiko stopped producing King Seiko's in 1975 to allow the emergence of the Grand Seiko as the undisputed high-end Seiko watch.\u003c\/p\u003e\n\u003cp\u003eSo, for Seiko Collectors and Vintage fans, this is a King Seiko JDM SUWA in stunning condition with a beautiful Patina Dial! As already mentioned, there are also (cheaper) King Seiko's from DAINI that began King Seiko production before the SUWA factory, so one must be extremely vigilant as to what KS they are purchasing.\u003c\/p\u003e\n\u003cp\u003eThereby, this December 1973 model is one of the last few ever produced before production fully ceased in 1975; hence, it is equipped with the most updated 5626 movement.\u003c\/p\u003e\n\u003cp\u003eThis beautifully shaped silver case was also given a good cleaning and high-quality polish while maintaining its super sexy curves. Most age imperfections were removed without compromising the case shape. The crystal was given a good buff albeit scratches do remain however, they are not easily seen because the dial design camouflages them.\u003c\/p\u003e\n\u003cp\u003ePatina has grown on the crown in a very unique manner. A psychedelic design is the outcome with various colours that makes this watch extremely rare.\u003c\/p\u003e\n\u003cp\u003eThe signed crown is located at the 3H position and is nicely tucked away yet easily accessible. The date \/ day quickset works as it should by uncorking the crown to the first and second levels to adjust the date + day via clockwise or counterclockwise, and hands respectively.\u003c\/p\u003e\n\u003cp\u003eThe day quickset works - cool! But the date quickset does not work - not cool!\u003c\/p\u003e\n\u003cp\u003eThe day is in English and Kanji - cool!\u003c\/p\u003e\n\u003cp\u003eThe watch had undergone a good clean-up on 14 July 2026. It 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 excellent 5626 movement, it has an impressive 25 Jewels that operate at 28,800 BPH. The timing shows approximately 3 seconds deviation daily which is well within the 30 second requirements for by brand new modern automatic watch standards.\u003c\/p\u003e\n\u003cp\u003eThe case width and height are approximately 36.3mm (w\/o crown) and 41.4mm respectively. The lug width is 18mm and the strap can accommodate wrists up to 21cm; hence, this watch is suitable for men and the modern women.\u003c\/p\u003e\n\u003cp\u003eA brand hi-quality Seiko Signed Calf Brown Leather strap is provided as part of the deal. It comes with a KS Signed Silver Buckle.\u003c\/p\u003e\n\u003cp\u003eThe watch is 100% original Seiko components from this particular watch. No parts were replaced with aftermarket or modified parts.\u003c\/p\u003e\n\u003cp\u003eEven though the relevant seals and gaskets are in place, this timepiece has not been water-resistant tested due to its age.\u003c\/p\u003e\n\u003cp\u003eThe pictures provided show the watch in superb 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 the case-back gold medallion, documentation and original box, so an after-market box \/ case is provided.\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 is 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 someone special born in December 1973!\u003c\/p\u003e\n\u003cp\u003eThis is a rare Collectible King Seiko KS56 in stunning condition; so, be unique and own a December 1973 Birthday Watch that is almost impossible to source in such fine condition or purchase it for that special someone instead. In fact, purchase it as an investment or for the next generation to appreciate.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Altimate Group","offers":[{"title":"Default Title","offer_id":43635663765593,"sku":null,"price":1668.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0279\/7590\/9465\/files\/IMG20260714175531.jpg?v=1784131763","url":"https:\/\/shop.altimate.sg\/products\/birthday-watch-december-1973-king-seiko-5626-7041-ks56-jdm-suwa-25j-automatic-watch-fs","provider":"Altimate Group","version":"1.0","type":"link"}
