Housed in a 34mm stainless steel case with acrylic crystal, this reference reflects IWC’s understated design language of the period — clean lines, balanced proportions, and robust engineering. An honest vintage example with strong mechanical fundamentals.\u003c\/p\u003e\n\u003chr style=\"margin: 20px 0; border: none; border-top: 1px solid #e0e0e0;\"\u003e\n\u003ch3 style=\"margin: 16px 0 8px;\"\u003eWhy It’s Special\u003c\/h3\u003e\n\u003cp style=\"margin: 0 0 12px;\"\u003eIWC’s Cal. 85x automatic movements are widely regarded for their durability and technical refinement, forming the backbone of the brand’s mid-century watches. The Cal. 8531 adds date functionality while maintaining the same engineering integrity. This example offers an accessible entry into vintage IWC collecting, with original dial, handset, and case, supported by a mechanically sound movement.\u003c\/p\u003e\n\u003chr style=\"margin: 20px 0; border: none; border-top: 1px solid #e0e0e0;\"\u003e\n\u003ch3 style=\"margin: 16px 0 8px;\"\u003eCondition\u003c\/h3\u003e\n\u003cp style=\"margin: 0 0 8px;\"\u003eOriginal silver sunburst dial shows widespread spotting and patina consistent with age and historical moisture exposure; printing remains legible with no signs of redial, and applied baton indices and handset appear original with matching ageing. Acrylic crystal has been polished but retains visible surface wear and distortion at certain angles. Stainless steel case has been cleaned and lightly polished, with symmetrical lugs and overall solid structure, though edges show mild softening from prior work. Case-back brushing remains visible. Crown appears unsigned and may be a later replacement. Date wheel shows slight vertical misalignment within the window, with a faint trace of the previous date occasionally visible at the top.\u003c\/p\u003e\n\u003cp style=\"margin: 0 0 12px;\"\u003e\u003cstrong\u003ePerformance:\u003c\/strong\u003e Running accurately at around –2 seconds per day — evidence of an overhaul by an independent Japanese watchmaker prior to sale, supported by strong timegrapher results and overall presentation.\u003c\/p\u003e\n\u003chr style=\"margin: 20px 0; border: none; border-top: 1px solid #e0e0e0;\"\u003e\n\u003ch3 style=\"margin: 16px 0 6px;\"\u003eDetails\u003c\/h3\u003e\n\u003cul style=\"margin: 0 0 12px; padding: 0; list-style: none;\"\u003e\n\u003cli style=\"margin: 2px 0;\"\u003e\n\u003cstrong\u003eReference:\u003c\/strong\u003e 1693422\u003c\/li\u003e\n\u003cli style=\"margin: 2px 0;\"\u003e\n\u003cstrong\u003eMovement:\u003c\/strong\u003e IWC Automatic Cal. 8531\u003c\/li\u003e\n\u003cli style=\"margin: 2px 0;\"\u003e\n\u003cstrong\u003eSerial:\u003c\/strong\u003e 1 689 933 (\u003cmeta charset=\"utf-8\"\u003e\n\u003cspan\u003e≈ \u003c\/span\u003e1963–1965)\u003c\/li\u003e\n\u003cli style=\"margin: 2px 0;\"\u003e\n\u003cstrong\u003eCase:\u003c\/strong\u003e 34 mm stainless steel\u003c\/li\u003e\n\u003cli style=\"margin: 2px 0;\"\u003e\n\u003cstrong\u003eCrystal:\u003c\/strong\u003e Acrylic\u003c\/li\u003e\n\u003cli style=\"margin: 2px 0;\"\u003e\n\u003cstrong\u003eStrap:\u003c\/strong\u003e Aftermarket leather strap with aftermarket buckle\u003c\/li\u003e\n\u003cli style=\"margin: 2px 0;\"\u003e\n\u003cstrong\u003eInclusions:\u003c\/strong\u003e Watch only — no box or papers\u003c\/li\u003e\n\u003cli style=\"margin: 2px 0;\"\u003e\n\u003cstrong\u003eProvenance:\u003c\/strong\u003e Sourced from Japan and inspected in Melbourne\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"The Curated Dial","offers":[{"title":"Default Title","offer_id":48148155269352,"sku":null,"price":1150.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0756\/7953\/1240\/files\/06-iwc-1693422-hero.jpg?v=1774088907","url":"https:\/\/thecurateddial.com\/products\/iwc-automatic-date-cal-8531-1693422-1963-1965","provider":"The Curated Dial","version":"1.0","type":"link"}
