Patek Philippe Grand Complications Split-second Chronograph, Perpetual Calendar

The split-seconds chronograph and perpetual calendar Reference 5204 is heir to one of Patek Philippe’s most sought-after Grand Complications. It has been available since 2016 in two rose gold versions, one with a silvered opaline dial and chocolate brown alligator strap (5204R-001), the other with an opaline ebony black dial and rose gold Goutte (droplet) bracelet (5204/1R).

Patek Philippe offers connoisseurs a new variation on the rose gold case by combining this precious metal with a matching slate gray dial and strap. A rare and refined nuance that contributes to renewing the style of this great classic.

The entirely hand-polished rose gold case stands out for its sophisticated architecture, with a concave bezel and two-tier lugs. Despite the complexity of the movement, the indications on the “sunburst” dial stand out for their perfect legibility. The day and month are displayed in two in-line apertures at 12 o’clock. The date hand at 6 o’clock incorporates the moon-phase aperture.

Small seconds and the instantaneous 30-minute counter appear on two subdials at 9 and 3 o’clock. Two small round apertures display the leap-year cycle between 4 and 5 o’clock and the day/night indication between 7 and 8 o’clock – functions enabling accurate adjustment of the calendar. Whether by day or night, reading the time is facilitated by the applied hour-markers and Dauphine-type hands in rose gold, all with luminescent coating.

The transparent sapphire caseback offers a magnificent immersion into the heart of caliber CHR 29-535 PS Q, first introduced in 2012 on Reference 5204P-001. This movement is distinguished by its traditional architecture (manual winding, two column wheels, horizontal clutch) combined with seven patented innovations, including six for the chronograph and one for the split-seconds mechanism. An amazing sight enhanced by extremely meticulous manual finishing.

The new Reference 5204R-011 is worn on a shiny slate gray calf leather strap with an embossed alligator pattern and a rose gold fold-over clasp. Available with interchangeable sapphire crystal and solid casebacks, it is joining the two existing versions in rose gold.
