Patek Philippe Ref. 5204G-001 Split-Seconds Chronograph Perpetual Calendar

Combining two of Patek Philippe’s most iconic Grand Complications, the split-seconds chronograph with perpetual calendar Reference 5204 has been available since 2021 in a rose gold version with a slate gray dial and strap (5204R-011).

The Manufacture has revisited the style of this great classic by giving it a white gold case with an olive-green dial enhanced by a sunburst decoration that plays with the light and by a black-gradient rim creating a subtle depth effect. The watch is paired with a shiny olive-green calfskin leather strap featuring contrasting beige stitching and secured by a white gold fold-over clasp.

The entirely hand-polished case is distinguished by its refined construction, notably featuring a concave bezel, two-tier lugs and round chronograph pushers.

The harmonious dial layout, highlighted by the contrast between olive-green and white, ensures optimal legibility of the multiple displays: day and month in a double in-line aperture at 12 o’clock, date hand and moon phase aperture at 6 o’clock, small seconds and instantaneous 30-minute counter in two finely snailed 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 – indications enabling accurate calendar settings. Time readings by day or night are facilitated by applied baton-style faceted hour markers and white gold faceted dauphine hands, all with luminescent coating.

The transparent sapphire case back (interchangeable with a solid case back) enables one to admire all the technical complexity and manual finishing of CHR 29-535 PS Q caliber – with its traditional construction (manually wound, two column wheels, horizontal clutch) combined with seven patented innovations, including six for the chronograph and one for the split-seconds mechanism.

The new Reference 5204G-001 in white gold joins the existing rose gold Reference 5204R-011 in the collection.
