Patek Philippe Calatrava

About this reference

The Patek Philippe Reference 570 was produced from 1938 until approximately 1972. While most examples were cased in precious metals, the stainless steel variant is highly sought after due to its rarity and oversized 36mm case, which was significantly larger than the standard 30-31mm watches of that era. Collectors value the steel 570 for its flat bezel, sharp case lines, and diverse dial configurations, including sector dials and those with Breguet numerals. Early models typically house the 12-120 manual-wind caliber, while later versions utilize the 12-400 or 27-SC movements. On the secondary market, steel examples generally command prices in the low-to-mid six-figure range, depending on dial originality and case condition. A notable auction result occurred in 2021 when a rare two-tone sector dial steel 570 sold for over 3 million CHF, reflecting the extreme scarcity of specific steel configurations.
