W&W 2025: Patek Philippe Calatrava 8 Days ref. 5328G-001
One of our favorite watches this year, and the dark horse of Watches & Wonders 2025, is the new Patek Philippe Calatrava 8 Days Power Reserve (Ref. 5328G-001). This watch not only expands the Calatrava collection, but also adds another complication of pure elegance to the everyday watch. This new Calatrava features an instantaneous day and date display in windows with a hand at 6 o'clock and an 8-day power reserve indicator at 12 o'clock.
The watch is housed in a perfectly proportioned 18K white gold case with a diameter of 41 mm and a thickness of 10.52 mm, and houses a new movement. The case features Patek Philippe's signature guilloché pattern that wraps around the entire case.
The grainy blue dial features a stunning textured blue dial with a black gradient edge, adorned with white gold numerals and hour/minute hands with white luminous coating.
A small running seconds hand is located at 6 o'clock on the date and day subdials, which we think makes the design a little busy and a bit confusing if you take a quick glance at the date indication - although the seconds hand is shorter than the date indicator hand.
The Calatrava 8-Day ref. 5328G-001 comes with two interchangeable straps: one in blue calfskin with a fabric pattern and cream stitching, and the other in grained taupe calfskin. Both straps feature the newly patented three-piece folding clasp, which provides both increased security and wearing comfort while also allowing for quick, tool-free strap changes.
Movement
Flipping the watch over, you'll see the new in-house 8-day manual movement, the 31-505 8J PS IRM CI J, which consists of 256 parts and beats at 28,800 vph (4 Hz). This new movement perfectly balances classic design with cutting-edge innovation and features key technological advances, including the Pulsomax escapement with Silinvar escape wheel and lever, originally developed through the Patek Philippe Advanced Research Program.
The movement's twin series-spring barrels ensure precise operation for a full eight days (192 hours), and a ninth "backup" date is displayed in red on an arched indicator at 12 o'clock, reminding the wearer when it's time to wind the watch. The day and date display features an instantaneous jump function at midnight.
Imposing yet sophisticated on the wrist, the Calatrava 8 Day Power Reserve is a modestly sized watch with a diameter of 41mm and the iconic spike pattern on the side of the case, striking the perfect balance between imposingness and comfort.
