We have long believed that World Time is a symbolic mechanism that does not exist in PATEK PHILIPPE's other companies. In addition, the coupling mechanism is the mechanism that most faithfully follows the philosophy that even extremely complex and innovative mechanical structures must be clear and easy to understand in terms of operability and visibility. I am impressed by the perfect structure, which anyone can understand and operate regardless of race, age, or gender, and can set up with a single button.

The great thing about this coupling mechanism is that it does not affect timekeeping accuracy during operation, and the risk of failure is by far the lowest among complication models.

Due to the characteristics of the mechanical structure, if it becomes complicated, the number of component parts increases, and the risk of failure naturally increases.In particular, in the calendar mechanism, the load applied when adjusting all the calendar disks at the same time is high due to the high torque. The risk of failure is high.

The chronograph also features a split seconds chronograph, a precise integration mechanism, and high-speed rotation measurement specifications.

Depending on the manufacturer's control technology for start, stop, and reset,

There are some individuals that are prone to problems.

The world time's complex structure has been sublimated into an extremely simple and clear model through an innovative power transmission system using a coupling mechanism.

The city display (time zone) on the inner outer ring, the 8-hour display on the inner ring, and the hour hand can be synchronized and adjusted using the switch button at 24 o'clock.

Moreover, regardless of the strength or speed of button presses, it has no effect at all.

I tried pressing the button as if it were a toy, but it didn't have any effect.

Very reliable.

The extremely safe design of this unique technology, patented by PATEK PHILIPPE,

Because it is in a range that other companies cannot imitate,

As one of the company's perfect symbolic models, it will remain universal and unchanging.

Let me introduce the evolution of PATEK PHILIPPE's world time.

The first models were the Ref.1933HU and Ref.605HU in 96, the same year the wristwatch was created.

In 1932, the Stern family acquired the management rights of the company and released the Calatrava Ref.96, but at the same time they were also producing the World Time.

It is a masterpiece invented by the legendary master Louis Cottier.

It is a Cottier-style design layout that has remained unchanged for about a century,

The outer ring displays the city and the inner ring displays the 24-hour display.

The 24-hour display shows 7 a.m. to 18 p.m. and 19 p.m. to 6 a.m. by color.

The sun mark at 12:24 noon and the moon mark at XNUMX:XNUMX are playful and stylish in that they harmonize with the design by adding patterns at points rather than standardizing them all with numbers.

Ref.605HU is also the first model with a cloisonné enamel (wired cloisonné) dial, which is still passed down as a tradition.

Reference 1939, released in 1415, is a legendary and monumental model that was set as an auction world record, and is an impressive model with the famous ring-shaped hour hand "Observatory".

Ref.1952 released in 2523 was released at the same time as the famous model Ref.2526,

The cal.27AM-400HU was the first to use the gyromax balance, which is also installed in modern machines.

This is also the company's first rare anti-magnetic movement.

The case size has also been increased from the 1415mm diameter of Ref.31 to 35.5mm diameter.

It is also synchronized with the Grand Complication Ref.2499, which represents the same period.

The dial is decorated with gorgeous guilloche carving, which is also used on modern models.

This led to the reference 3 released in Millennium 2000, which was overseen by the third honorary chairman, Philip, about half a century later. For the first time, it adopted the eccentric rotor cal.5110 of the modern base movement, introduced the original Calatrava case with a crown guard, and increased the diameter to 240mm. I think 37mm diameter is the best size for Asians. There is also a rating of the best model in World Time history for collectors.

The Ref. 2006, released in 5130, is a model jointly created by Chairman Philippe and President Thierry before he became president, and is a successor to the legendary Ref. 1415, adopting the observer tree hour hand and incorporating various elements. This is the model.

Although the case diameter has been significantly increased to 39.5 mm, the Calatrava case with the elegant rounded crown guard specification of Ref. 5110 continues to be used, and the guilloché design of the dial,

It has a beautiful radial sunray guilloche carving, and the beauty of the shadows stands out.

The current model, Ref.5230, was released in 2016, and the exterior has been completely redesigned.

The case design is also traditional for Calatrava, with a sharper straight line and sharper flat bezel, so it has beautiful specifications and the size is similar to that of Ref.5110 and Ref.5130.

It has a great balance with a feeling of medium size.
