Footnotes:
The Reference 533 first appeared in 1937. It is regarded by many Patek Philippe aficionados as the quintessential vintage chronograph because of its elegantly simple Calatrava case and characteristic flat bezel. The Reference 130 houses the same movement Calibre 13' but it is aesthetically distinguished by a concave bezel.

Although its production run lasted for 20 years, the 533 was made in very restricted numbers. It is estimated that the total production was around 350 pieces. Of those, the majority were cased in pink gold and fitted with a pink gold dial.

The model is illustrated in Patek Philippe Wristwatches by Martin Huber & Alan Banbery, second edition, p. 264.
