Reference 5170, a manually wound two-register chronograph was launched in 2010 and was initially available only in yellow gold as reference 5170J. A white gold version of the reference was introduced in 2013 as reference 5170G.
The model offered a new look compared to its predecessor, the reference 5070. The tachymetre scale has been replaced by a 15 pulsation scale, found on some rare earlier chronographs from the vintage era. Furthermore, for the first time, the reference houses the latest in-house calibre 29-535 PS with Patek Philippe’s new hallmark of excellence, the Patek Philippe or "PP" seal.
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.
