It typically features 21 jewels, operates at 18,000 vibrations per hour, and offers a power reserve of approximately 40–45 hours.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNoSpacing\"\u003e\u003cspan\u003eMost examples are configured with a small seconds display and incorporate Seiko’s Diashock shock protection system. Produced for a relatively short period, the Caliber 54 reflects Seiko’s move toward more refined and higher-grade domestic movements at the end of the 1950s. The early King Seiko models were based on the Cronos movement.\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Studio Tokei","offers":[{"title":"Default Title","offer_id":53711259664730,"sku":"S54-5961-001","price":425.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/1532\/2714\/files\/IMG_3968-2.jpg?v=1772308694","url":"https:\/\/studiotokei.com\/products\/seiko-cronos-j14021","provider":"Studio Tokei","version":"1.0","type":"link"}
