Product Detailed Description

TW Factory Patek Philippe Calatrava 5212A Weekly Calendar 40mm Watch

The TW Factory Patek Philippe Calatrava 5212A Weekly Calendar combines a 40mm stainless steel case with a multi-indication calendar display and Cal.26-330 automatic mechanical movement.

Unlike a conventional three-hand Calatrava, the 5212A incorporates calendar information directly into the dial layout, including the date, day, month and week indication.

A sapphire crystal with anti-reflective coating protects the dial, while a leather strap and traditional pin buckle maintain the restrained character of the Calatrava design.

40mm Stainless Steel Case

The watch features a 40mm stainless steel case.

The dimensions provide a balanced format for displaying the additional calendar information while maintaining relatively traditional round-case proportions.

Stainless steel offers good resistance to everyday wear and creates a neutral exterior appearance that keeps attention focused on the detailed calendar dial.

The 40mm diameter also gives the watch a contemporary wrist presence without requiring the larger dimensions commonly associated with sports watches.

Weekly Calendar Dial

The defining feature of the 5212A is its Weekly Calendar display.

Rather than limiting calendar information to a conventional date window, the dial organizes multiple indications to provide a broader overview of the calendar.

The displayed calendar information includes:

Date
Day of the week
Month
Week indication

These indications are incorporated into the dial alongside the primary time display.

The result is a more information-rich layout than a conventional Calatrava while retaining a relatively clean overall structure.

Week Indication

The week indication is an important distinguishing feature of the 5212A.

It allows the wearer to reference the week within the calendar year in addition to reading the conventional day, date and month information.

This functionality is particularly useful in environments where schedules, business planning or project timelines are commonly organized according to week numbers.

Cal.26-330 Automatic Movement

The TW Factory configuration is equipped with a Cal.26-330 automatic mechanical movement.

The supplied functions include:

Hours
Minutes
Central seconds
Date
Day
Month
Week indication

Automatic winding allows normal wrist movement to replenish the movement’s stored energy during regular wear.

If the watch has remained unworn for an extended period, it can be manually wound before setting the time and calendar indications.

Mechanical accuracy may vary depending on regulation, power reserve, temperature, resting position and individual wearing habits.

Central Seconds Display

The movement provides a central seconds hand, keeping running seconds integrated with the primary hour and minute display.

This configuration avoids the need for a separate small-seconds sub-dial, leaving more dial space available for the Weekly Calendar indications.

Multi-Scale Calendar Layout

The 5212A uses multiple dial scales to organize its calendar information.

The day, month and week indications are distributed around the dial rather than concentrated in several conventional calendar windows.

This arrangement gives the watch a distinctive technical appearance while preserving the round architecture associated with the Calatrava collection.

Because several pieces of information are displayed simultaneously, correct alignment of the calendar indications is an important part of the overall presentation.

Sapphire Crystal with Anti-Reflective Coating

The dial is protected by a sapphire crystal with anti-reflective coating.

Sapphire provides high resistance to everyday scratches and excellent optical transparency.

The anti-reflective treatment helps reduce surface glare, which is particularly useful for a watch with multiple calendar scales and relatively detailed dial information.

Strong direct impacts against hard surfaces should still be avoided.

Leather Strap

The watch is paired with a leather strap.

Leather complements the classic round case and provides a more traditional appearance than a stainless steel bracelet or rubber strap.

To maintain the strap, prolonged exposure to water, sweat, perfumes and aggressive chemical cleaning products should be avoided.

If the leather becomes damp, allow it to dry naturally away from direct heat.

Pin Buckle

The leather strap uses a traditional pin buckle.

This straightforward closure system allows the strap to be adjusted according to wrist size and maintains the restrained styling of the overall watch.

The buckle and strap holes should be checked periodically for excessive wear.

100m Water-Resistance Specification

The supplied TW Factory specification lists the watch with 100 meters of water resistance.

Actual water resistance depends on the condition and assembly of the crown, seals, crystal and overall case structure.

A stated water-resistance specification should not automatically be treated as confirmation that every individual watch has been independently pressure tested to that depth.

Because this configuration uses a leather strap, prolonged water exposure should also be avoided.

Professional pressure testing is recommended before swimming or intentional water exposure.

Wearing and Care Advice

When adjusting the Weekly Calendar indications, operate the crown and any calendar-setting mechanism gently.

Avoid forcing the calendar mechanism if unusual resistance is encountered. Calendar adjustments should also be performed carefully around the movement’s automatic date-change period.

Clean the stainless steel case with a soft microfiber cloth and avoid abrasive polishing compounds.

Keep the leather strap away from prolonged moisture and chemical cleaning products.

Protect the Cal.26-330 automatic movement from heavy impacts and strong magnetic fields.

Professional pressure testing is recommended before intentional water exposure.
