{"product_id":"calatrava-3820","title":"Calatrava - 3820R","description":"\u003ch3\u003eDescription\u003c\/h3\u003e\n\u003cp\u003eThe Patek Philippe 3820 R is a beautifully understated rose gold Calatrava from the late 1980s to early 2000s — an era when Patek was producing some of the most refined and restrained dress watches in the history of Swiss horology. The \"R\" suffix denotes the case material: 18ct rose gold, then referred to by Patek as \"red gold,\" lending this example a warmth and rarity that the more commonly encountered yellow gold variants simply cannot match.\u003c\/p\u003e\n\u003cp\u003eRose gold Calatrava references from this period are genuinely scarce on the secondary market, and the 3820 R occupies a compelling position for the collector who values both aesthetic character and historical provenance. The characteristic \"Clous de Paris\" (hobnail) bezel frames the white dial with Roman numeral hour indices and elegant black feuille hands — a composition of timeless simplicity that has not dated in the decades since its production.\u003c\/p\u003e\n\u003cp\u003e The small seconds sub-dial at 6 o'clock, powered by the ultra-thin manually wound Calibre 215 PS operating at 28,800 vph with a 44-hour power reserve, completes a dial layout of quiet, authoritative perfection. At 33mm, the case wears with the slim, dressy proportion that defined the finest Swiss watchmaking of the period, and pairs beautifully with the brown leather strap and 18ct rose gold pin buckle.\u003c\/p\u003e\n\u003ch3\u003eSpecifications:\u003c\/h3\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"50%\"\u003e\u003cstrong\u003e\u003cbig\u003eMovement\u003c\/big\u003e\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd width=\"50%\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eMechanical Manually Wound\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCalibre\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eCalibre 215 PS\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Reserve\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eApprox. 44 hours\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunctions\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eHours, Minutes, Small Seconds (6 o'clock)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e28,800 vph (4 Hz)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"50%\"\u003e\u003cstrong\u003e\u003cbig\u003eCase\u003c\/big\u003e\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd width=\"50%\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCase Material\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e18ct Rose Gold\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCase Diameter\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e33.0 mm\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBezel\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e18ct Rose Gold — \"Clous de Paris\" hobnail pattern\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCrystal\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eSapphire crystal\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDial Colour\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eWhite\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDial Indicators\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eRoman Numerals; black feuille hands\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 17px;\"\u003e\n\u003ctd width=\"50%\" style=\"height: 17px;\"\u003e\u003cstrong\u003eStrap\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd width=\"50%\" style=\"height: 17px;\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 34px;\"\u003e\n\u003ctd style=\"height: 34px;\"\u003eStrap Material\u003c\/td\u003e\n\u003ctd style=\"height: 34px;\"\u003e\u003cspan\u003eBrown Leather\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 14.75px;\"\u003e\n\u003ctd style=\"height: 14.75px;\"\u003eClasp\u003c\/td\u003e\n\u003ctd style=\"height: 14.75px;\"\u003e\u003cspan\u003ePin Buckle\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 17px;\"\u003e\n\u003ctd style=\"height: 17px;\"\u003eClasp Material\u003c\/td\u003e\n\u003ctd style=\"height: 17px;\"\u003e\u003cspan\u003e18ct Rose Gold\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEra\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eca. 1988–early 2000s\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Patek Philippe","offers":[{"title":"Default Title","offer_id":52049743085864,"sku":"3820","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2517\/4164\/files\/Screenshot2026-07-03at1.14.16pm.png?v=1783048482","url":"https:\/\/swissemporium.com.au\/products\/calatrava-3820","provider":"Swiss Emporium","version":"1.0","type":"link"}
