About the Patek Philippe Grand Complications

The line begins with the ref 1518 of 1941, the first perpetual calendar chronograph made in series, and runs through the 2499, the 3970 of 1986, the 5970 and the 5270 of 2011, which was the first with a movement made entirely in-house. The minute repeater returned in 1989 for the company's 150th anniversary, and the Sky Moon Tourbillon of 2001 and the Grandmaster Chime of 2014 sit at the top of the catalogue with twelve and twenty complications.

Two movements explain most of the collection. The CH 27-70 Q, a Lemania 2310 base with Patek's perpetual calendar, powers the 3970 and 5970 and 34 references here; the Lemania piece explains what Patek changed. The caliber 240 Q put the perpetual calendar on the ultra-thin micro-rotor movement in the 3940 of 1985, and it and its descendants appear in 19 references; the 240 piece covers that family. The in-house CH 29-535 PS Q of the 5270 follows at 19, the CHR 27-70 Q split-seconds of the 5004 at 16, and the automatic R 27 PS minute repeater at 15. 174 of the 270 are hand-wound.

Platinum is the most common material at 84 references, then white gold at 64, rose gold at 46 and yellow gold at 42; 12 are steel. Sizes run from 29.6 mm to 49.4 mm, with 37 mm, 41 mm and 36 mm the most common. 95 references have a minute repeater and 48 a tourbillon. The largest families are the 5538G and 5531R minute repeaters and the 5270G and 5016P. The glossary defines the grand complication itself.

Complications is the tier below, for annual calendars, chronographs and world timers, and the Calatrava is the time-only line.
