Reference 5074 was launched in 2002 only in yellow gold available with a silver or a black dial. In 2005 during the Basel fair, Patek Philippe presented the rose gold version. It is considered the successor to the famous ref. 3974. The mechanism is the same for both models, except for the striking mechanism.
Reference 5074 is equipped with calibre 27RQ that consists of 467 individual parts, with a movement height of only 6.8 mm. The movement is a technical masterpiece fitted in the smallest of spaces, with an oscillating mass driven by a 22 K gold micro-rotor, a perpetual calendar and a minute repeating mechanism. On demand, the minute repeater strikes the hours, the quarter-hours, and the minutes that have elapsed
since the last quarter-hour on two extra-long "cathedral" gongs made of special steel, and were shaped to encircle the movement not just once, but nearly twice. This makes them almost twice as long as conventional gongs and poses an enormous challenge to the watchmaker to accommodate them in the confined space available.
The perpetual calendar shows the day of the week and the 24 hours on a sub-dial at 9 o'clock; the month and leap year indication on a sub-dial at 3 o'clock. At 6 o'clock is the date display and an aperture with the moon phase display. This is so precise that it only deviates from the actual moon phase by one day after more than 122 years.
