Overview

The Calatrava Weekly Calendar 5212A-001 stands out as one of Patek Philippe’s most original recent calendar watches. Housed in a 40 mm stainless-steel case, it features a silver dial with a unique, hand-written style font used for the day, date and week indications, referencing the look of an annotated calendar or notebook.

At its core, the watch combines classic Calatrava proportions with a novel weekly calendar mechanism driven by the in-house automatic Calibre 26-330 S C J SE, offering central hours and minutes, sweeping seconds, day and date displays, and an indication of the current week of the year.

This example goes a step further from the standard configuration by pairing the steel case and silver dial with a blue alligator leather strap and a folding clasp, transforming the aesthetic into something more individual and contemporary without compromising the watch’s original spirit.

Design & Wrist Presence

The 40 mm stainless-steel case delivers a modern, balanced presence on the wrist. Slim lugs, polished and brushed surfaces, and the clean Calatrava silhouette make the watch versatile enough for both business and casual wear.

The silver dial is where the 5212A truly distinguishes itself. The layout features:

• central hours and minutes

• sweeping central seconds

• day-of-the-week display

• date

• a week-of-the-year indicator arranged around the periphery

All calendar markings are rendered in a hand-written style typography, giving the watch a uniquely personal, slightly “analog” character. It feels like a high-end mechanical interpretation of a hand-annotated paper planner—subtle, but very different from traditional printed calendars.

By default, the 5212A-001 is delivered on a beige strap with a pin buckle. This particular piece has been reconfigured with a:

• blue alligator leather strap that brings out cooler tones in the steel case and silver dial and adds contrast and depth;

• folding clasp instead of the standard pin buckle, providing a more secure feel on the wrist and helping to reduce wear on the strap over time.

The result is a 5212A-001 that still looks unmistakably like the Calatrava Weekly Calendar, but with a more distinctive, slightly sportier and more contemporary presence.

Movement & Performance

Inside the case beats the in-house Calibre 26-330 S C J SE, an automatic movement developed by Patek Philippe. According to your data, it offers:

• automatic winding

• hours, minutes, sweeping central seconds

• day-of-the-week indicator

• date

• week-of-the-year indicator

• approximately 35 hours of power reserve

The movement is visible through the open caseback, allowing you to appreciate the finishing, rotor and overall architecture. The integration of the weekly calendar into the movement provides real-world utility for anyone who works with weeks and deadlines rather than just calendar dates.

With a rated water resistance of 30 m / 3 bar, the 5212A-001 is designed for everyday urban wear: resistant to splashes and normal daily exposure to water, while clearly remaining a refined, non-sport watch to be kept away from swimming and immersion.

Key specifications:

• Caliber: 26-330 S C J SE, in-house, automatic

• Power reserve: 35 hours

• Functions: hours, minutes, sweeping seconds, day, date, week-of-the-year

• Water resistance: 30 m / 3 bar

• Case back: Open

• Buckle on this example: Folding clasp 

• Strap: Blue Alligator

Why this example is special

Most 5212A-001 watches are seen in their standard configuration: beige strap with a pin buckle. This example is different:

• Fitted with a blue alligator leather strap instead of the original beige strap, giving the watch a more striking, contemporary and individual look.

• Upgraded to a folding clasp instead of a pin buckle, improving security on the wrist and reducing stress on the strap over time.

These changes make this 5212A-001:

• more visually distinctive among other Weekly Calendar pieces,

• more practical and comfortable for frequent wear,

• and more aligned with clients who prefer the feel and security of a folding clasp on a high-end calendar watch.
