Vacheron Constantin Patrimony Traditionnelle Worldtime

One of the oldest houses in Europe watch Vacheron Constantin has a long history creating watches with world time display. However, for the past fifteen years, this complication in the regular catalog factory was absent, and the space was needed to fill. Admittedly, the long-awaited Patrimony Traditionnelle Worldtime in its conception and execution exceeded the most optimistic expectations.
Unfortunately, often trying to understand the device any time and complexity once again casting doubt on its practicality and applicability, we forget that behind every module is an invented story of the progress of our civilization that any complications are closely associated with the discoveries, changes in consciousness and lifestyle. Watch complications - is well-preserved members of human history.



Time and roads
By the middle of the XIX century watchmakers have achieved considerable success in the issue of timing, but the overall global time system was in chaos. Each state some arbitrarily sets its own local time based on the position of the sun, and in each city it can vary. In truth, this is unlikely at that time could even be called a problem, but in 1825 in England, built the first railroad in the world of general use, and further development of transport could not face the question of creating a single temporal system. Of course, the first decade of modest length of roads and the small number of trains allowed to ignore these inaccuracies, but when in 1880 a Canadian inventor and engineer Sir Sandford Scottish Flemming took the design of the Canadian Pacific Railway, which have had to go through eight time zones, to ignore the problem became too dangerous. Neither of which a single schedule of trains and the safety of their motion to speak in such terms was not necessary.
According to legend, the idea and determination in her incarnation came to Sir Fleming in 1876, when, due to inconsistencies in the local time of two towns in Ireland he was late for very important for a train. Three years later, speaking at the Royal Canadian Institute in Toronto, he put forward a proposal to divide the planet into 24 time zones of 15 degrees, each with a single universal time for each zone, that is, as would be placed in the center of the Earth's common hours.
Such an initiative for several reasons adopted by rather cold and met with considerable resistance, but all the same in 1884 in Washington at the International Conference meridian 25 nations reached an agreement and chosen as the prime meridian of Greenwich London suburb. One can guess that France, without the slightest excitement greeted this decision in favor of his eternal rival, especially since the Paris Observatory, was three years older. Not served as a convincing argument, even the paradox of our time the fact that the sun was rising in Brest on 50 minutes later than in Strasbourg. So in 1891, the French government has set a single for the whole country Paris time, which differed by more than 9 minutes from time to time in other European countries. In exchange for the adoption of standard GMT French demanded that the British decision metric system, which was invented in France in the late XVII century. While in Paris in 1911 still synchronize its time with the pan-European, London, its part of obligations never fulfilled.



 According to an old British tradition of day in GMT standard did not start in the usual midnight and noon. Fix this "fad" was only in 1928, when instead of GMT coined the term UT (Universal time). The last significant change was effected in 1972, when the standard was adopted by UTC (Coordinated Universal Time), based on atomic time.
Neutrality against the world time
In addition to establishing a single standardized time system, Sir Sandford Fleming joined the hour-long history as the initiator of the construction of the world's first watch with indication of all 24 time zones. Even before the adoption of a uniform standard, he ordered in 1880 at the London studio of some pocket watches Cosmic Time, showing the time in each zone on a single dial. It was the first WorldTimer in the modern sense of this function, although it is known about the earlier copies of pickpockets displaying the local time of different cities.
Today, the Earth was still divided into 24 time zones, each of which in theory should occupy 15 degrees of the surface, but a variety of geopolitical circumstances make this an ideal system of their practical correction. For example, China, occupying the area four zones, uses only one. For political reasons, India, Iran, Afghanistan, Myanmar, and Venezuela and other states have moved their local time by half an hour from the time of their local time zone, UTC, and in Nepal and on the coast of New Zealand's local clock is a 45-minute difference from the other states of the same meridian. So really working time zones on Earth for more than 24. But more on that later.



Despite the introduction of a uniform standard in 1884, for a long time watchmakers for many reasons in no hurry to create tools to display world time (no particular need, then there is insufficient demand, perhaps, be called a key factor). For another legend, creating an additional obstacle of class hours WorldTimer was a famous Swiss neutrality: the need to designate on the face of "capital" each time zone has been associated with the risk of offending other state in this zone. So up to 30 years of XX century, world time clock with virtually no set up, and their invention of the modern familiar to us as connected with the name of the outstanding kabinote Louis Kote. The rapid growth as their popularity was due to a jump of communications and international air and rail links.
This WorldTime
The family had a long-Kote and close relationship with Vacheron Constantin. Father Emmanuel Kote, also a watchmaker, had a shop in the suburb of Carouge in Geneva and at the beginning of the XX century house known for collecting automatons and clocks, so the choice of profession for his son was not really very complicated issue. Survived even a letter dated 1930 the year in which Louis Kote shortly after the death of his father wrote to Charles Constantine's desire to get a job at the factory, and in a postscript he added: "Among the things my father I found very original mechanism without hands, which may be of interest to you."

However, gaining momentum the Great Depression 30's not allowed to become a member of St. Louis factory. Nevertheless, the cooperation of families continued, and soon it became Vacheron Constantin caliber first base for the invention of Kote, made ​​him famous in the history of watchmaking. The essence of it is very elegant: display local time, the two central arrow was associated with a 24-hour ring rotating counterclockwise. Fixed on the outer ring of the dial was located, indicating the reference cities each time zone. In "12:00" was a reference point - the local town owner, while the ring was synchronized with the time indicated by the arrow, so you can optionally specify doobedenny or afternoon period of days in this city. Thus, at each time clock shows the time in every time zone in one neat dial.

Picture Dial Louis Kotte
It is important to understand that despite the huge number of different engineering solutions and terms in the model name, now existing in watchmaking - GMT, Dual Time, Time Zones and others who are able to display the time in some time zones or choose the city to display other time zones name WorldTimer can only wear watches, simultaneously displaying the time in all time zones.
The first pocket WorldTimer for Vacheron Constantin was founded by Louis in December 1932, but accepted that the earlier hours with the system Kote had ordered from the jeweler named Bezanger Carouge. Therefore, strictly speaking, Vacheron Constantin can not be considered the first clock with world time (although there are serious suspicions that the mechanism of the first few hours of time with the logo of the world Beszanger was actually built as a time for Vacheron Constantin). Over the next 20 years manufactory successfully produced a pocket watch with world time, which enjoyed great demand among the rich and powerful celebrities and royals. Kote system subjected to various refinements and improvements, but the basic principle remains unchanged. In the late 30s Vacheron Constantin released a series of clocks with world time, which were listed on the face of an impressive 67 towns.

In general we can say that a set of cities on the dials are often carried more intrigue and gives an indication of influence and primacy of a political and economic center of gravity. When ordering the factory clock, the client can arbitrarily specify a list of cities he needed, and thus greatly personalize favorite subject, favorite vacation spots indicate the address or frequent business trips.
The world's first wrist WorldTimer, Geneva textiles created for the Egyptian dignitary in 1957, apart from the usual structure contains one major innovation: the first system Kote was supplemented with a rotating disk with the cities, which allowed the owner to change the town if you want local time, for this rotation is complying with the additional head in the "9:00". Also later this option is implemented with a rotating outer welt, which deposited the title. In the modern history of the time aware of the existence of two versions of "world time" from the VC - a model of Phidias (1992-1996 gg.) Limited edition model and Evasion for Japan (2002-2003 gg.).
With this necessarily "have to do something," so in the 80 th anniversary of the debut of the invention Kote Louis Vacheron Constantin presented a model of the Patrimony Traditionnelle WorldTime, which brought world time clock with a new level.
Lambert projection
Three years ago, R & D team led by Vincent Kofman, following the famous motto of the house Vacheron Constantin «Do better when possible, but it is always possible to" set a goal to create the ideal clock with world time. As previously mentioned, a number of reasons really now on this planet there are not 24 time zones, and 37. Thirteen additional zones have a half-hour (Iran, India, Afghanistan, Myanmar, Australia Adelaide, Australia Kingston, Australia Lord Howe Island, Canada St. John's, the Marquesas Islands in Polynesia, and Venezuela) or 45-minute (New Zealand Waitangi, the Australian Euclid and Nepal) deflection. So you create a mechanism would be able to "recognize" is whether the chosen time zone full or fractional time zone - this is for the design meets a set of special dogs and antennae.
Also, designers Vacheron Constantin could not ask a simple question: What would happen if a country decides to change his hour mode, because then the clock will stop correctly display the world time? For such a case the new device caliber 2460WT provides for easy replacement of the control ring on the new addition, of course, need to change and to drive to cities. And very soon this foresight paid off: in the next month after the January presentation at the SIHH in Geneva, a new model of Russian President announced the cancellation of the transition to winter, and thus the Moscow time zone changed from GMT +3 to GMT +4. Ring and face were soon replaced in order to reflect this correction.
After the cancellation of the transition to winter time Moscow permestilas from GMT +3 to GMT +4
In addition to the construction of convenient and thoughtful attention mechanism, of course, was to detail the dial - an essential element of any WorldTimer'a. The dial is composed of three main parts. The first - the metal, with the Lambert map projection centered at the North Pole and city names. According to Mr. Kofman, selection of an option card emphasizes superior manufacturability hours, because the conical Lambert projection is often used in aeronautical maps as Distorting the minimum projection of three-dimensional image on a two-dimensional. Cities are black, are in full time zones, as indicated by the red half-hour and fifteen zones.
The View from Inside
The second part - sapphire, with the shading in the "night" part. This part makes one revolution per 24 hours, gradually covering the darkness of night one part of the map and simultaneously opening the morning light, the opposite. Interestingly, this idea came a member of the Design Department Vacheron Constantin during the flight. Requesting the airplane in the air, he saw a map of the Earth, divided into dark and light part of the night and day, respectively, and decided to take this finding into service in WorldTime. In addition, this glass is engraved with the application of ink-hour mark. The third part - a metal ring fixed to the external applied by means of decalcomania minute scale and overlaid with gold hour markers.
Despite the complexity and sophisticated design Patrimony Traditionnelle WorldTime differs surprising ease of use - all settings are made with a single crown. The owner selects the time zone and puts it in front of the black triangle in the "6:00". In this central part of the dial with a map and cities, respectively, rotate. time in the time zone can be read either by the arrows on either 24-hour drive, while the remaining 36 time zones are also recorded.
The new manufactory caliber 2460WT makes 28 800 vph, has 40-hour power reserve and is marked by the Geneva hallmark, its unique design features patented. Also worth noting housing rose gold - 42.5 mm in diameter at a thickness of 11.5 mm, which is to recognize the ideal settings for today for men's watches.
From the side of the dial: caliber 2460 is equipped with a WT control ring with 37 teeth of various lengths (1), recognizes whether the time zone full or fractional. The wheel is controlled by a system of dogs (2) and antennae (3).
From the side of bridges: caliber 2460, which replaced the automatic chronometer 2450, was originally designed as a "tractor": COSC certified chronometer with a stop-second, where you can build on any modules. 2460 came out in the version with perpetual calendar and a "floating" display for a series of Metiers d'Art. 22K gold sector is mounted on ceramic bearings (4)
Creating such a brilliant both technically and in registration hours will Vacheron Constantin to strengthen its position among the guards of manufactories, and collectors will add a pleasant headache searching for the opportunity to become owner of the first "world time" with the indication of all existing on our planet today's time zones.
