The 6602, formerly known as Cal 957, made its debut circa 1961. This movement is normally found in Seiko Sportsman and Seahorse models.\u003c\/p\u003e\n\u003cp\u003eThis extremely rare two-toned Seiko 6602-1990 Gold-Filled Sportsman Calendar Mechanical watch brings sexiness to a new level! Its original ivory white dial is in very good condition. However, miniscule patina (Wabi-Sabi: The Perfect Imperfection \/ The Imperfect Perfection) is making a subtle entrance and a sort of Roman Marble design will come into effect in a decade's time or more. The 14K solid gold indices, hands and date window is in superb condition after a good cleaning.\u003c\/p\u003e\n\u003cp\u003eMost such models were cannibalised for their indices \/ lumens to replace those damaged in Seiko 62Mas Diver's watches that had greater value. Hence, not many fully original Gold-Filled watches of this model exist thereby making this timepiece literally a \"one-of-a-kind\" and highly sort after due to its increasing scarcity.\u003c\/p\u003e\n\u003cp\u003eFor Seiko Collectors and Vintage fans, this is a JDM gold-filled Seiko SUWA Seikosha Sportsman Calendar 6602. Unlike other Sportsman's, the seahorse is not found on the case-back because this watch was not designed for diving but can be used for other sports such as golf, tennis, bowling et cetera, and act as a dress watch in the evening ~ clever.\u003c\/p\u003e\n\u003cp\u003eThe gentleman-like cylindrical shaped gold-filled case was buffed as best as possible; however, there are some hairline scratches still present. The crystal was given a good rub-down and is now in excellent condition albeit scratches do exist. \u003c\/p\u003e\n\u003cp\u003eThe crown is located at the traditional 3H position and is easily accessible. The crown has been replaced with a brand-new signed crown. There is no typical quickset for the date change. The date change requires a semi-quickset - for the hands to move from 8H to 4H and back. Please take note. \u003c\/p\u003e\n\u003cp\u003eThe movement was carefully stripped, cleaned, oiled, re-assembled and calibrated on 31 August 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 iconic 6602 movement, it has 17 Jewels that operate at 18,000 BPH. The time-grapher shows excellent readings of -1 second and amplitude of 238! 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.\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 genuine leather saddle strap can accommodate wrists up to 21.0cm; hence, this watch is suitable for men and the modern women.\u003c\/p\u003e\n\u003cp\u003eA brand-new good-quality beautifully crafted hand-stitched crocodile designed genuine leather rosewood strap with matching stitching and gold buckle is provided to enhance the colour of the case and dial.\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 pictures provided show the watch in excellent condition, and the movement within squeaky clean and well maintained. It has also been de-magnetised to improve parts reliability, minimise wear + 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 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 two-toned that has minimally aged 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 special someone born in September 1964.\u003c\/p\u003e\n\u003cp\u003eThis particular timepiece is valued between S$ 290.00 to S$ 688.00 on various auction \/ online sites from really horrible, to un-serviced, to \"as is,\" to serviced, to refurbished models. Note: the mentioned prices do not include currency conversions, commissions, taxes and freight costs etc.\u003c\/p\u003e\n\u003cp\u003eThis is a highly sort-after Seiko Sportsman Calendar 6602-1990 with a classy Red Rosewood Leather Dress strap that compliments the case and dial perfectly; so, be unique and own a September 1964 Birthday Watch that is almost impossible to source in such fine condition or purchase it for that special someone instead.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Altimate Group","offers":[{"title":"Default Title","offer_id":44633477185625,"sku":null,"price":446.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0279\/7590\/9465\/files\/IMG20260831140323.jpg?v=1788163624","url":"https:\/\/shop.altimate.sg\/products\/birthday-watch-september-1964-seiko-sportsman-calendar-6602-1990-suwa-jdm-17j-gold-filled-mechanical-wrist-watch","provider":"Altimate Group","version":"1.0","type":"link"}
