{"product_id":"3970ep-second-series-perpetual-calendar-chronograph-platinum","title":"3970ER, Second Series, Perpetual Calendar Chronograph, Pink Gold","description":"\u003cp\u003e\u003cspan\u003eA ref. 3970 from the Second Series in pink gold. Just 60 Second Series examples are estimated to have been manufactured in pink gold, out of 650 across all metals. The 3970 succeeded the 2499 in 1986, the most significant contribution of Philippe Stern’s tenure over the brand. It features a 36mm Ateliers Réunis case, Lemania ébauche calibre CH 27-70 Q, feuille hands of early series, ‘American Typewriter’ font, and warmer Argenté dial of early series. It is the Perpetual Calendar Chronograph that did more with less; despite a smaller size and greater degree of information displayed than the 2499 that preceded it, the 3970 succeeded in making immense complication not just easily understood, but beautiful. This is a particularly well-preserved and beautiful example, offered with its full set. \u003c\/span\u003e\u003c\/p\u003e","brand":"Hairspring","offers":[{"title":"Default Title","offer_id":60141561544785,"sku":null,"price":400000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0617\/0830\/4465\/files\/Patek-Philippe-3970R-Second-Series-55.jpg?v=1787702862","url":"https:\/\/hairspring.com\/products\/3970ep-second-series-perpetual-calendar-chronograph-platinum","provider":"Hairspring","version":"1.0","type":"link"}
