Patek Philippe - Reference 5204G-001 Split-seconds Chronograph Perpetual Calendar

The new Patek Philippe 5204G-001 in white gold with olive-green dial combines Split-seconds Chronograph and Perpetual Calendar. Price: €318,370

Combining two of Patek Philippe’s most coveted grand complications, the new Reference 5204G-001 Split-seconds Chronograph Perpetual Calendar in white gold with olive-green dial joins the red gold version with slate gray dial that was presented in 2021.

The watch comes in a 40 mm x 14.3 mm case entirely polished by hand that is characterised by a concave bezel and two-tier lugs. Water resistance is guaranteed up to a pressure of 3 bar (30 metres / 100 feet).

The olive green sunburst dial with a black gradation to the periphery displays the day and month in two in-line apertures at 12 o'clock while the current date is indicated in the subdial at 6 o'clock, also incorporating the moon-phase aperture.

Small seconds and the instantaneous 30-minute chronograph counter are positioned on two subdials at 9 and 3 o'clock. The small round aperture between 4 and 5 o’clock is used to display the leap-year cycle while the one between 7 and 8 o’clock indicates whether it is day or night. 

The gold Dauphine hour/minute hands and the applied baton-style faceted hour markers are treated with luminescent coating for improved legibility in darker environments.

The split-seconds chronograph function allows lap and intermediate times to be stopped without interrupting an ongoing measurement. The two seconds hands are started and stopped by pressing the button at 2 o’clock. Pressing the split-seconds button in the crown will stop the split-seconds hand only. By pressing the split-seconds button again, the split-seconds hand will swiftly catch up with the chronograph hand.  The button at 4 o’clock resets the two superimposed hands to zero.

The transparent sapphire crystal of the caseback reveals the hand-wound calibre CHR 29-535 PS Q, a 4 Hz (28,800 vibrations per hour) movement with two column wheels and horizontal clutch that features seven patented innovations, including six for the chronograph and one for the split-seconds mechanism. 

The watch is delivered with interchangeable sapphire crystal and solid casebacks. With the chronograph disengaged,  the autonomy is between 55 and 65 hours.

Matched to a shiny olive-green calfskin strap with beige contrast seams secured with a white-gold fold-over clasp, the new Patek Philippe Ref. 5204G-001 Split-seconds Chronograph Perpetual Calendar has a suggested retail price of Euro 318,370. patek.com
