Patek Philippe Reference 5204R-011: Split-seconds Chronograph and Perpetual Calendar with Rose Gold Case and Slate Gray Dial

Patek Philippe has expanded the Grand Complications family by launching a new version of Reference 5204 Split-Seconds Chronograph and Perpetual Calendar watch.

This multi-complication mechanical timepiece 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 now presents a new variation with a rose gold case and a matching slate gray dial and strap.

The entirely hand-polished and sophisticatedly styled rose gold case is equipped 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 the view the CHR 29-535 PS Q Split-seconds Chronograph and Perpetual Calendar Caliber. First introduced in 2012 on Reference 5204P-001, this meticulously finished manual-winding movement incorporates seven patented innovations, including six for the chronograph and one for the split-seconds mechanism.

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 case-backs, it is joining the two existing versions in rose gold.
