With the new Calatrava Alarm reference 5322G, Patek Philippe brings the alarm function back to the forefront of its grand complications in a more contemporary and streamlined form.
Presented at Watches and Wonders Geneva 2026, the new model focuses on a 24-hour alarm mechanism striking on a classic gong, housed in a white-gold Calatrava case distinguished by Clous de Paris guilloché on the caseband and paired with textured lacquered dials in either blue or green.
While the technical foundations originate from the calibre developed for the Pilot Alarm Travel Time ref. 5520 introduced in 2019, the new reference 5322G removes the dual-time display and centres attention on the alarm function itself.
The result is a cleaner and more balanced layout, combined with a more versatile aesthetic that aligns with the recent evolution of the Calatrava collection.
The dial adopts the textured, black-gradient style first seen on references 5226 and 5326.
Its granular lacquered surface transitions from blue or green at the centre to black around the outer edge, while white-gold applied numerals and syringe-shaped hands filled with luminescent material reinforce legibility.
The central seconds hand and date hand are executed in white-painted steel, with the latter indicating the date on a recessed subdial at 6 o’clock.
The upper section of the dial is dedicated entirely to the alarm indications. A double aperture at 12 o’clock displays the programmed alarm time, with the hours shown on the left and the minutes on the right in 15-minute increments.
Just below, a small circular aperture indicates whether the programmed time falls during the day or night.
A bell-shaped aperture above the display changes colour depending on the status of the alarm: white when activated and black when deactivated.
The 41 mm white-gold case features openworked lugs and a continuous Clous de Paris hobnail guilloché decoration extending around the entire caseband.
To preserve the uninterrupted pattern, the lugs are attached directly to the caseback rather than integrated into the middle case.
Despite incorporating a chiming mechanism, the watch is water-resistant to 30 metres (100 feet), making it the only water-resistant chiming watch currently in the Patek Philippe collection.
Operation has been designed to remain intuitive despite the complexity of the mechanism. The crown, unusually positioned at 4 o’clock, performs three different functions depending on its position.
When pushed in, rotating it clockwise winds the alarm barrel, while turning it anticlockwise winds the movement.
Pulled out halfway, it allows the alarm time to be adjusted forwards or backwards in 15-minute increments. Fully extended, it is used to set the time, with the balance stopping for precise synchronisation.
A single pusher at 2 o’clock activates, deactivates or interrupts the alarm, while a discreet corrector between 6 and 7 o’clock adjusts the date.
Visible through the sapphire-crystal caseback, the new self-winding calibre AL 30-660 S C is composed of 524 parts yet maintains a relatively slim profile at 6.6 mm thick.
Its architecture is derived from the calibre AL 30-660 S C FUS used in the Pilot Alarm Travel Time, but simplified here by removing the Travel Time mechanism.
The movement beats at 4 Hz (28,800 vibrations per hour) and uses a 21K gold central rotor for automatic winding.
The Gyromax balance and Spiromax balance spring in Silinvar contribute to chronometric stability, resistance to magnetic fields and long-term precision.
Particular attention has been paid to the striking mechanism itself. Unlike many alarm watches, where a hammer strikes directly against the caseback to produce a buzzing sound, the calibre AL 30-660 S C uses a traditional gong coiled around the movement, similar in principle to a minute repeater.
The hammer strikes this gong at a steady rhythm controlled by an inertial governor, producing approximately 90 strikes at a cadence of around 2.5 strikes per second.
The system has also been designed to avoid accidental misuse. The alarm cannot be activated unless the striking barrel is fully wound, a process requiring around ten clockwise turns of the crown.
Once the power stored for the striking mechanism is exhausted, the watch automatically switches to OFF mode.
Reference 5322G is available in two versions: the ref. 5322G-001 with a navy-blue dial paired with a navy-blue composite strap featuring a fabric texture, and the ref. 5322G-010 with a green dial combined with a green patinated alligator strap.
Both versions are additionally supplied with a beige nubuck calfskin strap and fitted with Patek Philippe’s patented triple-blade fold-over clasp designed for easy strap interchangeability.
The new Patek Philippe Calatrava Alarm references 5322G-001 and 5322G-010 are priced at €267,297. A three-minute video presenting the main features and mechanisms of the new model is available below. patek.com
