Patek Philippe Perpetual Calendar Split-second Chronograph 5204R-011, the correct use of color

The Planlevac-based manufacturer once again demonstrates its ability to elegantly present highly complex timepieces in warm tones.

It was launched in 2016 in a series of versions that combine a 40 mm diameter rose gold case with a black or silvery opaline dial. The perpetual calendar split-second chronograph will be launched by Patek Philippe at the end of this year in a new version, the 5204R-011. While the precious metal case remains, it is now combined with a slate grey dial that tends towards grey-brown. In this decoration, as refined as ever, one finds the calendar display with day and moon apertures located on the same row at 12 o’clock, as well as the date indicated by a hand at 6 o’clock. The moon phase is also located on this dial. For measuring short and long-distance running times, the 30-minute counter at 3 o’clock is combined with two useful seconds hands for a split-seconds function. A small seconds hand at 9 o’clock, a leap year indicator, and another dedicated hand to distinguish between day and night at 7:30.

The hour and minute hands point to a circle of hour markers, both coated with luminescent material for optimal legibility. These and all other data are precisely powered by the CHR 29-535 PS Q movement, which has a power reserve of 65 hours. Assembled from 496 components, this hand-wound mechanism is complex in its construction and its sublime finishing can be admired through the sapphire backing of the case.

The natural elegance of this timepiece is further enhanced by the calfskin strap with a grey alligator scale pattern and fitted with a folding clasp.
