Patek Philippe presents a new Calatrava model with an original 24-hour central display for local time and home time. referee. The 5224R-001 is powered by a Calibre31-260 PS FUS 24H with three patents.

Patek Philippe Calatrava 24 Hours Display Travel Time Ref. 5224R-001 is a regular production timepiece.

Calatrava is the quintessential Swiss round dress watch. It is the embodiment of elegance and tradition, synonymous with the Patek Philippe brand. In recent years, however, there has been a shift toward bringing Calatrava into the 21st century in order to be more in sync with today’s trends. Patek Philippe has never been afraid of change. The brand knew it needed to evolve in order to stay relevant. The latest example of Patek Philippe’s efforts to modernize the Calatrava collection can be seen in the new Ref. here. 5224R-001 (and Ref. 6007G, which debuted in Watches and Wonders 2023).

referee. The 5224R is not what you usually imagine when you think of a classic Calatrava. It has a blue dial, a 42mm case, sporty numerals, a time display in an atypical 24-hour format, and a matching brushed blue calfskin strap. That is, these seemingly modern design elements are tempered by the traditional fine craftsmanship that continues to define Patek Philippe. For example, the Calatrava has a larger case, but has a refined and fully polished look. While the main time display in 24-hour format may seem novel, it was actually inspired by the Patek Philippe No. P-527 pocket 1:1 Quality Replica wathes produced more than a century ago for the Brazilian retailer Gondolo & Labouriau. Then, when you turn the watch over, you find a mechanical movement with traditional architecture and you’re done.

All in all, Ref. The 5224R manages to strike a delicate balance between old and new worlds while keeping it fresh with an unorthodox 24-hour time display.

Patek Philippe has expanded its extensive selection of Travel Time dual time zone watches with the new Calatrava model, which features the original display of local time and home time by means of two central hands that turn a 24-hour circle. The manufacturer has used 24-hour displays in the past, notably on the Chronometro Gondolo watches produced for the Brazilian retailer Gondolo & Labouriau in the early 20th century. One of them is a pocket watch made in 1905, which is now displayed in the Patek Philippe Museum (No. P-527). For the new Reference 5224R-001, the designers have reinterpreted this type of indication in a decidedly contemporary spirit. They also chose to place the noon time at 12 o’clock instead of the usual 6 o’clock, ensuring excellent daytime legibility.

To provide these functions, Patek Philippe’s engineers took the 31-260 ultra-thin self-winding base movement and added a 24-hour mechanism and a travel time mechanism. Launched in 2011 in the annual calendar regulator ref. 5235 (caliber 31-260 REG QA), it was completely reworked in 2021 for the inline perpetual calendar ref. 5236P-001 (caliber 31-260 PS QL). It operates at 4 Hz (28,800 semi-oscillations per hour) with a 20% increase in barrel spring torque, a platinum micro-oscillating weight (heavier than gold) for increased winding power and a reduction wheel When the watch is manually wound, It disconnects the automatic winding mechanism, which reduces wear. In 2022, Patek Philippe redesigned the movement again for the annual calendar travel time reference 5326G-001 (caliber 31-260 PS QA LU FUS 24H) and developed several innovations, resulting in the application for eight patents. The new caliber 31-260 PS FUS 24H movement, reference 5224R-001, benefits from three of these patents, designed to optimize efficiency, accuracy, durability, safety and ease of use.

Through the transparent sapphire crystal case back, you can see the new self-winding movement caliber 31-260 PS FUS 24H with platinum mini-rotor, whose elegant craftsmanship (9.85 meters high) is very suitable for the Calatrava model. line, Patek Philippe also replaced the traditional local time correction pusher on the left side of the case with a patented correction system that uses a crown that is pulled out to the middle position (backwards and forwards in one-hour increments). Modeled on the device used in reference 5326G-001 in 2022. The fully polished rose gold case, 42 mm in diameter, is inspired by the Calatrava weekly calendar ref. 5212A-001 launched in 2019 and features curved double lugs.

The navy blue dial shines with its elegance and legibility, enhanced by the twin-track hour and minute markers. The 24-hour display, alternating Arabic numerals and hour markers, and cabochon 5-minute hour markers represent a total of 44 rose gold appliqués – polished together to achieve the same brilliance and individually set by hand. The Travel Time Dual Time is indicated by three syringe-shaped hands in rose gold, the local hour and minute hands are coated with luminescent coating, and the center of the home hour hand is hollowed out. Delicate finishing touches create a beautiful play of light and shadow on the dial: a circular striped centre, a circular satin-brushed hour circle and the snailed small seconds with a rose gold-plated outline. The navy blue calfskin strap features a nubuck finish and contrasting cream stitching that matches the color of the dial. It is secured by a rose gold pin buckle.

Several Patek Philippe patents are reapplied to this new movement, including – for the time zone component – three patents from the caliber 31-260 PS QA LU FUS 24H (ref. 5326G-001): • Time setting in three crown positions (
Swiss patent CH 716383 B1 published 29.07.2022)
This time-setting system has a three-position lever that deactivates certain wheels as long as they are not performing any corrections. This reduces energy consumption and wear on the corresponding wheels. The result is a gain that balances magnitude (rate accuracy) and reliability. quartz replica watch

• Linear time zone spring (European patent EP 3650953 B1)
  The system consists of a star wheel and a jump spring. It allows a strong increase in torque between the local time and home time wheels – thus providing the user with more precise information.
• Inertia gain (European patent application EP 3822711 A1)
  This mechanism counteracts the difference in inertia between heavier and lighter wheels. It prevents accidental forward or backward misalignment of the time display (home time, local time, minutes) when the time zone is corrected in either direction. This increases the accuracy of the display.
