Released a couple of weeks ago at Baselworld 2017, the new Patek Philippe Calatrava ref. 6006 is the new version of the now discontinued Patek Philippe ref. 6000. This iconic watch with an off-centered seconds subdial and a pointer date indicator on the periphery of its dial just got even better with a more wearable case size now measuring 39 mm in diameter opposed to 37 mm as in all of its previous iterations that are now all gone.
