About the Complications family
Complications is Patek Philippe's catalog heading for useful everyday functions that stop short of the grand complications. It covers the annual calendar, which Patek introduced in 1996 with ref. 5035 and which needs correcting only once a year, the World Time with its city ring, Travel Time models with two hour hands, chronographs, moon phases and alarms.
References in the catalog include annual calendars such as the 5205 and 5396, World Times such as the 5230 and the enamel-dial 5231, and the Calatrava Pilot Travel Time models. Calibers include versions of the 240, 324 and 26-330 families. For dealers the exact reference and dial variant matter most, as the same function often comes in several metals and dial colours that trade differently.
