Patek Philippe 5130 World Time Watch
The functionality of today’s mechanical watches is gradually diversifying. Even the most basic hours, minutes, and seconds have been made by design masters ‘unrecognizable’ and other auxiliary functions are even more. The most commonly used timing tools have surpassed the original concept, giving designers who are eager to mechanical watches a wider stage to show their original and innovative ideas. The 24 o’clock display is the most frequently used function in the watch. Below I will give you a detailed introduction to various forms of the 24 o’clock function.
This function of the mechanical watch uses the principle of division of world time, that is, the division of longitude. Its definition is the angle between the point on the earth and the poles and the plane where the 0 degree meridian is located. The longitude of the original site of the Greenwich Observatory in London, the capital of the United Kingdom, is defined as a 0 degree meridian, and then extends left and right.
In fact, the longitude is the angle between the planes of the two meridians, so that each region on the earth can be distinguished, and the time zone of each place is divided by this. Every 15 longitudes differ by 1 hour. This division method can Each major city in the world is arranged side by side in a circular manner according to every 15 longitudes, that is, an hour difference. They are made into a circle on the surface. There are many brands with this time zone display function, and Longines has so A mechanical watch is more classic.
Recently, Zenith launched a more complicated mechanical watch with this function. The feature of this watch is that the dial is printed with the name of the main city of each country in the world, and the inner side near the dial is Set a 24 o’clock circle that can be quickly adjusted, set the gear through the crown, and then according to the time of a city at this time, align the time number displayed on the 24 o’clock circle with this city. Driven by the core’s own gear, you can always know the exact local time in these cities, which greatly facilitates people who need to know this information, which is also in line with the breath of the current information age.
