The Patek Philippe Quadruple Complication 5308G-001 features an elegant ice-blue sunburst dial, which is complemented by faceted applied hour markers and faceted sword-shaped hands in blue metallized white gold. The dial is carefully designed to ensure that all 13 displays controlled by the R CHR 27 PS QI movement are clearly visible. Three arc-shaped windows are arranged between 10 and 2 o'clock, each displaying the day, date, and month of the perpetual calendar, and are framed by blue metallized white gold. The date window is slightly larger to highlight important information. In addition, a circular window is set at 8 and 4 o'clock, respectively, to display the day/night and leap year cycles, allowing for precise adjustment of the calendar display.

Patek Philippe chose white gold to cast the case to house this high-performance mechanism. The white gold case of this watch is the same design as the Ref. 5208 model, with a diameter of 42 mm. The classic and elegant white gold case is hand-polished throughout, with a concave bezel and hollow lugs, which is particularly distinctive. This watch is equipped with two interchangeable casebacks, one sapphire crystal caseback and the other white gold caseback. The shiny navy blue alligator leather strap is equipped with a new white gold patented three-folding clasp to ensure comfortable and secure wearing.
According to the design specifications, the new movement must be compact enough and as thin as possible. In the end, the technicians successfully developed the new R CHR 27 PS QI movement, which only increased its thickness by 1.93 mm (from 10.35 mm to 12.28 mm) despite the addition of 80 parts (a total of 799 parts, 719 parts for the R CH 27 PS QI movement). In order to better integrate the split-seconds function, which consumes the same amount of energy as the running chronograph device, the designers decided to improve the movement performance in many aspects. The leaf spring is made of a stronger material and thicker, while the size of the spring stem is reduced, so that the barrel torque can be increased while the length, number of turns and power reserve (at least 38 hours and up to 48 hours when the chronograph function is turned off) remain unchanged, thus better controlling the split-seconds device. To this end, the inertia of the balance wheel must be increased through a chain reaction to avoid the "knocking" phenomenon (the impact on the escapement caused by the balance wheel's excessive amplitude) and improve the travel accuracy. In addition, the watch replaces the 22K gold eccentric mini-rotor with a platinum mini-rotor. Platinum is heavier and can enhance the winding power to ensure smooth winding of the new barrel.
The instantaneous perpetual calendar in the window embodies superb craftsmanship and is created for a few selected timepieces. It is equipped with an exclusive device with two patents. This device was equipped with the Ref. 5207 watch released in 2008 and the Ref. 5208 watch released in 2011. This system alone has 220 of the 799 parts in the movement, allowing the day, date, month and leap year displays to jump instantaneously every 30 milliseconds, even when the power reserve is only 10 hours. This function is made more complicated by the fact that the display is a disc, which consumes much more energy than the pointer display. The instantaneous display must precisely harness the energy to control the disc jump and then release it in an instant. The large fork consists of 15 parts, some of which are mobile (first patent) to ensure that all the displays jump precisely and synchronously. The design includes two complementary instantaneous springs placed opposite each other (second patent), which ensure that the energy consumed for each change is constant, even if the displacement angle varies greatly, such as a single-day instantaneous jump at the end of a long month (31 days) and a four-day instantaneous jump at the end of February in an ordinary year. This design avoids incomplete instantaneous jumps due to insufficient power or excessive jumps due to excess energy.
