The large Calatrava model reference 570 was introduced into the market in 1938, featuring either subsidiary or sweep centre seconds. To many collectors, the reference 570 is amongst the most perfect time only Patek Philippe watches in terms of shape and size. It was available in yellow, pink and white gold, platinum, and very rarely, in stainless steel. Accordingly, of all case metals, stainless steel examples of the reference are the most coveted. The present steel example is fresh to the auction market, and is offered in superb condition. The case is well preserved, the bezel and lugs are remarkably well defined and crisp. It’s fitted with a superb, two-tone opaline dial, highlighted by a brushed silver peripheral ring giving it great character. The Gay Frères riveted stainless steel bracelet, with its rare and desirable expandable links, adds a dash of elegant nonchalance to the timepiece. Vintage Patek Philippe wristwatches, where aesthetics, condition and rarity all mix into a potent formula are what collectors are looking for and the present “Calatravone” (Italian for large Calatrava) is certainly a gem for the savvy collector.
