Patek Philippe expands its complication range with the new 2025 Calatrava featuring a day/date display with eight-day power reserve. The movement is the all new manually wound calibre , 31-505 8J PS IRM CI J, including the innovative Pulsomax escapement and Silinvar escape-wheel and lever (developed for the advanced research program). The dial is a cool textured blue colour and shows day, date, time and the 8 day power indicator. The stunningly simple white gold case has a hobnail fine detailed case side and the movement is on show through the sapphire crystal case back. The watch is supplied with two straps which fit to the new white gold patented triple blade fold over clasp.
