{"product_id":"rolex-daytona-black-16520-1996","title":"Rolex - Daytona – Patrizzi – 16520 – 1996","description":"\u003cp\u003eThe Rolex Cosmograph Daytona ref. 16520 marked a turning point for the model line, introducing Rolex's first self-winding movement to the Daytona after decades of manual-wind execution, and it quickly became one of the most sought-after references in the collection. This example carries a genuine \"Patrizzi\" dial, named for the Geneva auctioneer Osvaldo Patrizzi, who first drew collector attention to a subset of early 16520 dials whose chronograph sub-registers have oxidized from black to a warm brown or chocolate tone over time, a naturally occurring lacquer reaction rather than a factory specification. Cased in 40mm Oystersteel with Rolex's signature tachymeter bezel and a steel Oyster bracelet, the contrast between the black dial surface and the tropical sub-dials is exactly what collectors seek out in a genuine Patrizzi example.\u003c\/p\u003e\u003cp\u003eInside is Rolex's Caliber 4030, a self-winding chronograph movement developed from a Zenith El Primero base and substantially reworked by Rolex, including a reduction of the beat rate to 28,800 vibrations per hour and the addition of Rolex's own chronograph module. The movement offers a power reserve of approximately 50 hours, and the case carries 100 meters of water resistance with Rolex's screw-down pushers and crown, a Daytona hallmark that keeps the chronograph functions sealed against moisture during use.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Rolex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e Cosmograph Daytona\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReference:\u003c\/strong\u003e 16520\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase:\u003c\/strong\u003e Oystersteel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Diameter:\u003c\/strong\u003e 40mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial:\u003c\/strong\u003e Black with oxidized \"Patrizzi\" (tropical) sub-dials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMovement:\u003c\/strong\u003e Caliber 4030, self-winding chronograph (Zenith El Primero-based)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Reserve:\u003c\/strong\u003e Approximately 50 hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrystal:\u003c\/strong\u003e Sapphire\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Resistance:\u003c\/strong\u003e 100 metres\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrap\/Bracelet:\u003c\/strong\u003e Oystersteel bracelet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctions:\u003c\/strong\u003e Hours, minutes, small seconds, chronograph (30-minute and 12-hour registers), tachymeter scale\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecial Features:\u003c\/strong\u003e Genuine Patrizzi tropical sub-dials, a rare and highly sought-after dial variant on this reference; Rolex's first self-winding Daytona movement; screw-down chronograph pushers\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Investment Watches Inc","offers":[{"title":"Default Title","offer_id":57405723803974,"sku":"A2403","price":39850.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0630\/5559\/3658\/files\/IMG_8284_7694b6b2-ca78-4ccd-a30b-ad9fed77580d.png?v=1790704228","url":"https:\/\/www.investmentwatches.com\/products\/rolex-daytona-black-16520-1996","provider":"Investment Watches Inc","version":"1.0","type":"link"}
