As part of Patek Philippe’s celebration of their 150th anniversary, the company introduced this self-winding minute repeater with perpetual calendar and moon-phase in 1989. This example is made in yellow gold with the case manufactured by Jean Pierre Hagmann, as can be seen underneath the lug at the 7 o’clock position.
The dial is glossy black lacquer with applied Breguet numerals. This dial’s particular claim to uniqueness lies with the Calatrava cross featured underneath the maker’s signature on the dial.
