Patek Philippe has achieved a world first by offering its sophisticated grand complication CHR 27-525 PS calibre, the world’s thinnest split-seconds column-wheel chronograph, in an elegant new pink gold model for women, the Ladies First Split Seconds Chronograph. On the front, the bezel is set with 153 diamonds and frames a very elegant grained opaline dial, while another 76 diamonds decorate the sapphire caseback which reveals the movement.
