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The legendary Gyromax balance wheel, patented by Patek Philippe in 1948 and in 1951, has been replaced by a four-armed balance wheel, on which four movable regulation weights are fixed - a measure that facilitates the precision adjustment.
