Patek Philippe Grand Complications Calatrava 24-Hour Alarm 5322 White Gold / Green

The Patek Philippe Grand Complications 5322G-010 5322G-010 debuted in 2026 as a white gold Calatrava equipped with a 24-hour alarm, pairing a contemporary alarm display with a more traditional case architecture. In this reference, the complication is presented with a textured green lacquered dial and a hobnail-decorated caseband, giving the watch a distinct visual identity within the Calatrava family while preserving the relatively balanced display of the model. Its case is crafted in white gold and measures 41 mm in diameter with a thickness of 12.22 mm. The overall profile is shaped by both the alarm mechanism and the decorative treatment of the exterior, with the entire circumference of the caseband guilloched with a hobnail pattern. The same motif extends to the pusher, while the lugs are skeletonized, giving the case a more elaborate structure than a standard time-only Calatrava. A sapphire crystal case back reveals the movement, and water resistance is rated to 30 metres, a notable specification in the context of a chiming Patek Philippe wristwatch. The dial is executed in textured green lacquer with a black-gradient rim. White gold applied numerals and syringe-shaped hands, all with luminescent coating, maintain legibility against the darker dial surface while reinforcing the slightly more technical character of the watch. The date is shown by hand in a subdial at 6 o’clock, while the alarm indications are displayed through apertures rather than auxiliary hands. The alarm time is presented digitally in 15-minute increments, and separate apertures indicate alarm on or off status and the relevant day or night phase. This arrangement gives the watch a more instrument-like interface than a conventional Calatrava, while keeping the dial composition relatively disciplined. Inside is the self-winding calibre AL 30-660 S C, a movement developed around the 24-hour alarm function and date display. The alarm chimes on a classic gong and is actuated by a single hammer. The movement measures 31 mm in diameter and 6.6 mm in thickness, consists of 524 parts, and uses 52 jewels. It is wound by a 21K gold central rotor and delivers a power reserve ranging from a minimum of 42 hours to a maximum of 52 hours. It operates at 28,800 semi-oscillations per hour and incorporates a Gyromax balance and Spiromax balance spring. In this watch, the movement is especially notable for combining a chiming alarm with water resistance, a relatively uncommon pairing in the Patek Philippe catalogue. The watch is fitted as standard with a patinated green alligator leather strap with square scales, secured by a patented triple-blade fold-over clasp in white gold. An additional beige calfskin strap with nubuck finish is also supplied. In this configuration, the strap shifts the watch away from the more casual composite treatment of reference 5322G-001 and gives it a slightly more classical tone, even as the textured green dial keeps the presentation contemporary. The result is a 24-hour alarm watch that combines a relatively unusual complication with a case and dial treatment that feels more assertive than a conventional Calatrava, while still remaining within the formal language of Patek Philippe’s Grand Complications.
