Vacheron Constantin successively launched the ultra-high-complex watch in 2010 last year. This year, in 2011, the goal was to increase the diversification of medium and complex models, as well as to continue the spirit of brand development. Patrimony Traditionnelle, which holds three patents, has inherited the classic World Time watch. Vacheron Constantin started from Jean-Marc Vacheron in 1755 and continued in 1819 when another founder Fran & ccedil; ois Constantin joined. He expanded the brand’s works to markets around the world through travel. The Chinese market, and the successors are inspired by watchmaking. With the establishment of the Greenwich Meridian as the starting point of longitude in the International Meridian Conference held in Washington in 1884, the world was divided into 24 time zones. The industry has set off a wave of craftsmanship that can track time in multiple places.
In 1932, Vacheron Constantin launched the first international time zone functional watch ‘Cottier System’ (model 3372). The movement was made by the Geneva watch genius, Louis Cottier, and displayed a mechanical movement with 31 time zones. In 1936, two world time zone pocket watches continued to be introduced. By 1937 and 1938, the brand introduced six table clocks with a mobile dial design that could display the time in 67 regions, including Paris’s summer and winter time. In the 1940s, the world time zone pocket watch model number 4414 was introduced. The dial can display 41 city times, and the 24-hour moving disc can be divided into two areas: day and night. Created the brand’s prestigious and superb achievements in the world time zone timepiece technology at the time. In 1957, Vacheron Constantin opened a new chapter in the history of world time zone timepieces. It was the first brand to apply the world’s time zone complications to watches. The model number was 6213, which was ordered by an Egyptian nobleman.
At this stage, most of the world’s time zone watches are 24 time zones, and Vacheron Constantin developed the Cal.2460 WT automatic mechanical machine in order to show the cities in the half time zone and the quarter time zone due to the influence of borders and political factors. The core, cast with the Geneva mark, covers 37 imaginable time zones in the world (patent pending); and when a city cannot represent its time zone, it must be replaced by adjusting a single part on the movement and Just replace the city name on the dial to keep the watch up to date. The display area on the dial is composed of three parts: the uppermost day and night indication (patent pending) inspired by the flight monitor, and with the assistance of the automotive glass supplier, the sapphire crystal dial is rendered bright and dark The day and night display is displayed, and a 24-hour display ring is engraved on it. The middle metal plate is painted with the Lambert Azimuthal Equal-Area Projection in the same color as the nautical chart, and 37 city names; the purpose is to want the watch to look like an instrument. At the bottom are the hour and minute metal rings. In addition, the hollow triangle decoration on the hour hand is the same as the clock on an airplane.
Although the movement of the Cal2460 WT is complex, it is extremely easy to use and operate. With a single crown (patent pending), the time zone and time can be adjusted. The wearer only needs to select the name of the city where he is located, adjust it to the black triangle mark at 6 o’clock, and then adjust the local time of the hour hand or 24-hour dial. The cities shown in black represent the entire time zone, and the red city names represent the half or quarter time zone. Patrimony Traditionnelle inherits the classic series of world time zone watches with practical and excellent complication display. It is a collection of innovation, exploration and superb craftsmanship, as well as a long and long history, which explains how humans roughly estimate time and read from the sundial. Timepieces that can read the accurate time of 37 cities at the same time, so that business or tourists have more convenient tools for travel.
