After having created a split-seconds chronograph with perpetual calendar in 2012, Patek Philippe is back on the theme by presenting a new calibre with a split-seconds function and no additional complication. It is the manual CHR 29-535 PS, with double column wheel and instantaneous 30-minute counter, housed in the platinum case of Ref. 5370. Very beautiful and classic is the dial in deep black enamel, with leaf hands and Breguet-style numerals, made from a white gold base covered in enamel, melted in an oven at a temperature of 850°C and then left to cool and harden until it takes on a glass-like consistency. The flange bears the tachymeter scale.
