Produced for three decades, from 1934 to 1964, reference 130 represents the archetype of the vintage Patek Philippe chronograph with Calatrava lines. Even though it was manufactured for a long period, production was quite limited, resulting in a total of about 1500 pieces produced.The cases, made primarily in yellow gold, were produced in rose gold, steel and steel-gold as well, but in much more limited quantities. The dials were also the subject of great experimentation, with different designs, indexes, numerals and scales.
