Reference 5270 was introduced to the market at the Basel Fair in April 2011 and replaced the celebrated reference 5970. The model houses calibre 29-535 PS with Patek Philippe's new hallmark of excellence, the PP Seal. This calibre was first introduced with reference 5170.

In 2009, Patek Philippe created a new quality benchmark for its mechanical timepieces: the Patek Philippe Seal. This new emblem of horological excellence goes beyond any existing standards of the Swiss watch industry. Uniquely, the Patek Philippe Seal applies to the completely assembled watch as delivered to its owner. In conjunction with these standards, the Seal represents a commitment to lifelong servicing and restoration for all timepieces created by the firm since 1839.
