The Patek Philippe Calatrava 8 Days 5328G-001 is a white-gold, manually wound watch announced at Watches and Wonders Geneva in April 2025. Its defining combination is an instantaneous day-and-date calendar, a minimum 192-hour power reserve and a textured blue dial. Patek Philippe’s product page displayed a price of $78,020 when checked in 2026; that is a changeable manufacturer-listed price, not a guaranteed transaction price.
What is the Patek Philippe 5328G-001?
The 5328G-001 is a Calatrava with an eight-day minimum power reserve and a calendar showing the day in an aperture and the date by hand. Patek Philippe introduced it at Watches and Wonders Geneva in April 2025. The manufacturer’s product page identifies it as the Calatrava 8 Days; its April 2025 launch release explains the movement’s design and calendar indications.
How long does the power reserve last?
Patek Philippe specifies a minimum power reserve of 192 hours, or eight days, for manually wound caliber 31-505 8J PS IRM CI J. The April 2025 launch release describes two barrels connected in series as allowing the watch to run precisely for eight full days, with a ninth day “in reserve.” That launch wording describes additional reserve; it does not replace the product page’s formal minimum rating of 192 hours.
Patek Philippe’s release says: “The difficulty is not just that, once wound, the watch must be able to function longer than the usual timepiece, but also –and especially –that it must retain its rate accuracy and stability for the duration of this increased autonomy.” The statement is attributed to the company, not to a named individual.
