**Gondolo Calendario Annual Calendar Moonphase Ref. 5135** is a luxury wristwatch by [[Patek Philippe]].

This model, presented on the [[Baselworld]] in April [[2004]], occurs this time, unlike the previous round [[Patek Philippe Annual Calendar 5035|Annual Calendar 5035]], with a [[tonneau]] case and shows in an unusual way date, day of the week and month in three windows, which are arranged on a circular arc between 10 and 12 o'clock. The 24-hours dial with the [[moon phase]] indication has remained in the lower half of the dial.

As usual at Patek Philippe, the most important innovations are rather hidden under the surface So the newly developed mechanical movement Calibre 324 with [[automatic]] winding is used, in which the [[rotor]] in 21ct gold was increased in radius and height to increase the winding power.

The legendary [[Gyromax]] [[balance wheel]], patented by Patek Philippe in 1948 and in 1951, has been replaced by a four-armed [[balance wheel]], on which four movable regulation weights are fixed - a measure that facilitates the [[precision adjustment]].

[[Patek Philippe]] won the Men's Watch Prize at the [[Grand Prix d'Horlogerie de Genève]] for the Gondolo Calendario 5135 G in November, [[2004]].
