{"product_id":"000000008641","title":"Sinn 656, original buckle, ETA 2824-2 automatic, overhauled, 2000s, pre-owned","description":"\u003cp\u003eThis is the 656, a classic timepiece from the 2000s that embodies Sinn's founding design philosophy of creating \u003cstrong\u003e\"watches for use.\"\u003c\/strong\u003e Although it is now discontinued, its rugged style and concept have been passed down to its \u003cstrong\u003eadvanced successor, the \"856.B,\"\u003c\/strong\u003e which focuses specifically on timekeeping by omitting the UTC (dual time) function. With an exquisite 38.5mm case size that fits perfectly on the Japanese wrist, this model remains a masterpiece with a deeply rooted popularity.\u003c\/p\u003e\n\n\u003cp\u003eIts most striking feature is its high visibility, reminiscent of aircraft instruments, with a functional, aesthetic design that emphasizes the 3, 6, 9, and 12 indices so that a pilot can grasp the time at a glance. The indices and hands are treated with luminous paint, ensuring sufficient visibility in dark conditions.\u003c\/p\u003e\n\n\u003cp\u003eThe case is crafted from bold, matte-finished stainless steel. The German inscription \"MAGNETFELDGESCHUETZT\" engraved on the case back literally means \"protected from magnetic fields.\" This confirms that a soft-iron inner case is incorporated inside the watch, shielding the movement 360 degrees. This special structure achieves an overwhelming magnetic resistance of \"80,000 A\/m,\" virtually blocking the influence of smartphones, PCs, and other sources that cause magnetization.\u003c\/p\u003e\n\n\u003cp\u003eThe watch is fitted with a \u003cstrong\u003e\"HAVANNA\" cowhide leather strap by the German company Di-MODELL\u003c\/strong\u003e. It is a high-quality leather strap from the same German brand as the watch itself, and it is attached with a \u003cstrong\u003egenuine Sinn buckle\u003c\/strong\u003e. This combination accentuates its stoic impression as a professional instrument.\u003c\/p\u003e\n\n\u003cp\u003eIn terms of practicality, it features a highly airtight screw-down crown and case back. The movement is powered by the highly reliable \u003cstrong\u003eETA 2824-2\u003c\/strong\u003e, which includes manual winding, a hacking seconds function, and a quick-set date, making it a highly convenient model for modern lifestyles.\u003c\/p\u003e\n\n\u003ch4 style=\"margin-top: 20px;\"\u003eCondition\u003c\/h4\u003e\n\n\u003cp\u003eThis watch has been \u003cspan class=\"marker\"\u003e\u003cstrong\u003eoverhauled\u003c\/strong\u003e\u003c\/span\u003e.\u003c\/p\u003e\n\u003cp\u003e\nAs this is a pre-owned item, there is no water resistance guarantee, but the screw-down action of the crown is in good condition.\u003c\/p\u003e\n\u003cp\u003e\nWhile slight surface scratches, visible only at certain angles, can be seen on the crystal, there are no deep scratches, and timekeeping remains unobstructed.\u003c\/p\u003e\n\u003cp\u003eThe crown threads are very delicate parts, so we recommend handling them slowly and carefully finding the correct engagement point without applying excessive force.\u003c\/p\u003e\n\n\n\u003ch4 style=\"margin-top: 20px;\"\u003eOperation\u003c\/h4\u003e\n\n\u003cp\u003e\u003cstrong\u003eUnlocking the crown\u003c\/strong\u003e: Rotate downward from the neutral position.\u003c\/p\u003e\n\n\u003cp style=\"margin-left: 40px;\"\u003eThe screw-down condition of the crown is good.\nWhen screwing the crown back in, we recommend searching carefully for the thread engagement point to avoid stripping the threads, and tightening it slowly.\u003c\/p\u003e\u003cp\u003e\n\n\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eManual Winding\u003c\/strong\u003e: Unlock the crown and rotate upward.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTime Setting\u003c\/strong\u003e: Pull the crown out to the second click and rotate downward (the second hand stops in this position).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQuick-set Date\u003c\/strong\u003e: Pull the crown out to the first click and rotate upward.\u003c\/p\u003e\n\n\u003cp style=\"margin-left: 40px;\"\u003e\u003cspan class=\"marker\"\u003eUsing the quick-set function while the watch hands are between 9:00 PM and 3:00 AM may cause a malfunction.\u003c\/span\u003e\u003cbr\u003e\nWe recommend setting the time to around 6 o'clock before performing a quick-set operation.\u003c\/p\u003e","brand":"WATCH COLLE","offers":[{"title":"Default Title","offer_id":56190477205809,"sku":"000000008641-001","price":0.0,"currency_code":"JPY","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1001\/4939\/5761\/files\/1_000000008641.jpg?v=1788948437","url":"https:\/\/watch-colle.com\/en\/products\/000000008641","provider":"WATCH COLLE","version":"1.0","type":"link"}
