The Patek Philippe Nautilus reference 5712 has the same exceptional reputation that also characterizes the reference 5711. It is the epitome of a luxurious steel watch. Only in one regard it is probably even more special than its sister model. While the 5711 is only equipped with a date, the reference 5712 is much more complicated. Inside ticks the legendary Patek Philippe caliber 240 (as 240 PS IRM C LU) with a golden micro rotor, which, in addition to the date, also offers a small second, power reserve display and moon phase. This reference probably connects the two worlds in which Patek Philippe excels more than any other: As the inventor of numerous complications, Patek Philippe is considered the most influential watch manufacturer in history and, with the introduction of the Nautilus, also one of the pioneers in the segment of luxurious steel watches. Hardly any watch represents these two facets better than the 5712.
