{"product_id":"iwc-caliber-89","title":"IWC Cal. 89 1951","description":"\u003cp\u003eIn the 1950s, the International Watch Company of Schaffhausen resumed the production of civilian watches after the war years. At the heart of this rebirth, the caliber 89 established itself as one of the house's most remarkable movements: a hand-wound manufacture movement, it combined robustness, precision, and unfailing reliability, true to IWC's tradition of excellence. Introduced in 1946 and remaining in production for over thirty years until 1979, this legendary caliber powers an elegant dress watch with a sober and timeless appeal. The engraving on the back reveals its history: gifted by Gebrüder Sulzer AG of Winterthur to one of its long-serving employees, it testifies to the Swiss tradition of rewarding loyalty and commitment with a durable, quality object.\u003c\/p\u003e\n\u003cp\u003eWrist size in photo\/video: 17 cm\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCase\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003eSteel\u003c\/li\u003e\n\n\u003cli\u003eDiameter: 31 mm without crown\u003c\/li\u003e\n\n\u003cli\u003eLight wear consistent with age\u003c\/li\u003e\n\n\u003cli\u003eKnurled crown signed with IWC fish logo\u003c\/li\u003e\n\n\u003cli\u003eEngraved Sulzer dedication on case back\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMovement\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003eCaliber 89, manual winding\u003cbr\u003e\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cmeta charset=\"UTF-8\"\u003e \u003cspan\u003eThis caliber is derived from Cal.83, the famous movement that powered many military watches during World War II.\u003c\/span\u003e\n\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eDial\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003eBeautiful patina, more pronounced on the edges of the dial\u003c\/li\u003e\n\n\u003cli\u003eLarge printed Arabic numerals, printed baton minute markers\u003c\/li\u003e\n\n\u003cli\u003ePatinated lume hour\/minute hands; very elegant blued steel central seconds hand\u003c\/li\u003e\n\n\u003cli\u003eSignature \u003cem\u003eInternational Watch Co.
