The Patek calatrava 6000 series is a relative young product range in the maison's storied history. Tracing its roots back to the 5000 series which debuted in 1992, the 6000 series was launched in 2005. It is equipped with the 240 PS C, a date variant of the venerable caliber 240 which celebrates its 40th anniversary this year.
The white gold anthracite dial version of this model was released in late 2007 and ended its run in 2015. As Patek introduced its own Patek Philippe seal in 2009, there is a small number (exact number unknown) of 6000g calatravas which bear the Geneva seal, and this is one of them.
Does this add to the monetary value of this watch? Probably not, considering that the reference (essentially the dial design) is very polarising and actually offends some hardcore fans of the brand.
But for me, it's a little detail that adds to my love for this beauty, and makes it extra special in my eyes!
