Patek Philippe introduced Reference 5040 in 1992 as its first tonneau-shaped perpetual calendar model. The 1930s-inspired case measures 35mm x 42mm, and as a monobloc case, it is fashioned from a single piece of metal.
The Perpetual Calendar 5040 was manufactured until 2007 and during that time, Patek offered this reference in yellow, white, and rose gold, in addition to platinum. The Patek Philippe Perpetual Calendar 5040R is the 18k rose gold version. It is estimated that fewer than 4,000 examples of the Reference 5040 (across all material options) were ever made.Other significant design touches of the Reference 5040 are the Breguet-style numerals and Breguet-style hands—two details that Patek typically reserves for special references. The 5040 was in fact the first (serially produced) Patek Philippe perpetual calendar to feature Breguet numerals on the dial.
