It’s well known that the Patek Philippe World Time has been a mainstay in the brand’s catalog since the mid-20th century, which is complex to build and also much easy to use. The Patek Philippe World Time ref. 5230G, the most update version of the famous watch, let’s go ahead of it now.
Today we may take it for granted, but the concept of standardized time zones did not appear organically in the past. On the contrary, it had to be formalized. Actually, it was only in 1884, at the International Meridian Conference in Washington D.C., when diplomats agreed to adopt a single Prime Meridian (located in Greenwich, England). This made a great contribution to the standardization of global time zones.

It’s until in 1931, Swiss watchmaker Louis Cottier announced a complication capable of displaying the times of the 24 time zones. Cottier’s world times mechanism smartly used a rotating bezel inscribed with 24 major cities, each represents a different time zone. After not long Patek Philippe was interested in Cottier’s world time complication. In 1937, Patek Philippe finally released their first world time replica designer watches: the round, yellow gold ref. 1415/1 HU (Heure Universelle) and the rectangular, pink gold ref. 515 HU due to Cottier’s movements.
As a successor to the previous World Time ref. 5130, Patek Philippe introduced the World Time 5230 at Baselworld 2016. The case of the ref. 5230 measures 38.5mm in diameter and 10.23mm thick. Normally Patek makes this Word Time watch in either 18k rose gold or 18k white gold, while the new version ref. 5230G is in white gold.
The size of the case (which is actually 1mm smaller than the ref. 5130) is just right, and elegance of the watch is emphasized without crown guards. Even if all the city names around the periphery, the design of the dial makes it super easy to read.

There’s a gray hand-guillochéd section at the center of the dial, housing the applied white gold hour markers and center hands. Note the shape of the pierced hour hand, which adds an intriguing design touch to the watch. Following the gray center is the 24-hour disk, and day hours (silver) and night hours (black) are fittingly split into color-coded.
How to set the Patek World Time watch rightly? At first make sure that your corresponding city is positioned at the top of the dial. You can switch through cities by just pushing the button on the side of the case of the 10 o’clock location. When your city is in position, then you can set the local time via using the winding crown to turn the center hands, at the same time please make sure that the appropriate day or night numeral on the 24-hour disk are positioned right below your city at 12 o’clock.

It’s rather easy to read all 24 time zones once local city and time are adjusted. Additionally, if you travel at another location, simply push the button at 10 o’clock to change the city at 12 o’clock accordingly.
You’ll view the fake Patek Philippe Caliber 240 HU via the sapphire casevacs when flip the watch around. In true Patek form, the movement is intricately hand-decorated with different finishes. Its well-known mini-rotor craft in solid 22k yellow gold along with the Patek logo engraved, which is a striking contrast to the predominately silver-tone of the movement. The automatic movement beats at a frequency of 21,600 vph and supplies a 48-hour power reserve for the World Time ref. 5230. In summary, the Patek Philippe World Time 5230G is rather excellent and functional.
