It was circa 1964 that Seiko abrogated the 3-digit to 4-digit model, thus the 402 became known as the 6102.\u003c\/p\u003e\n\u003cp\u003eFor Seiko Collectors and Vintage fans, this is a pre-SUWA (logo) Seiko 402 Skyliner AD in immaculate condition.\u003c\/p\u003e\n\u003cp\u003eThe 402 movement is one of the rarest mechanical movements and is one of the most highly sort after. This watch is a Collectible.\u003c\/p\u003e\n\u003cp\u003eThis extremely rare January 1963 vintage Seiko Skyliner's original silver Fine Linen dial has aged gracefully and has taken on a caramel colour that produces a golden syrupy dial at certain angles.\u003c\/p\u003e\n\u003cp\u003eThe case is in excellent condition and had undergone a painstaking cleaning process and most age marks and main scratches were removed albeit miniscule scratches do remain. The crystal was replaced with a hi-grade Japanese crystal and given a good polish.\u003c\/p\u003e\n\u003cp\u003eThe signed crown is original and is located at the 3H position and is nicely tucked away yet easily accessible.\u003c\/p\u003e\n\u003cp\u003eThe movement was carefully stripped, meticulously cleaned, oiled, re-assembled and basic calibration conducted on 24 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 402 movement, it has 21 Jewels and operate at 18,000 BPH. The time-grapher shows superb readings of +2 seconds and amplitude of 216 with a relatively straight line! Such readings are truly 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 the painstaking calibration conducted.\u003c\/p\u003e\n\u003cp\u003eThe case width and height are 35.9mm (w\/o crown) and 42.4mm respectively. The lug width is 18mm and the genuine leather saddle strap can accommodate wrists up to 21.0cm with ease; hence, suitable for men and the modern women.\u003c\/p\u003e\n\u003cp\u003eA beautifully crafted brand-new hi-quality Rally Designed genuine brown leather strap with gold buckle is provided as part of the deal.\u003c\/p\u003e\n\u003cp\u003eTo the best of our knowledge and expertise, the watch is 100% original Seiko components from this particular watch. No parts were replaced with aftermarket or modified parts.\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 shows the watch in excellent condition, and the movement within is 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\u003eYes, there are many other same models in the market, but almost all are not as well maintained as what you see here. Hence, this one-of-a-kind watch will make an extremely beautiful birthday present for that special someone born in January 1963. Another no-brainer is the fact that the value of this watch will appreciate over time.\u003c\/p\u003e\n\u003cp\u003eThis is a highly sort-after Seiko Skyliner Cal 402, so, be unique and own a January 1963 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","brand":"Altimate Group","offers":[{"title":"Default Title","offer_id":44263899824217,"sku":null,"price":399.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0279\/7590\/9465\/files\/IMG20260801152230.jpg?v=1785604569","url":"https:\/\/shop.altimate.sg\/products\/fast-deal-birthday-watch-january-1963-seiko-cal-402-j15006-skyliner-ss-21j-mechanical-watch-oh","provider":"Altimate Group","version":"1.0","type":"link"}
