Nel lontano 1932, Vacheron Constantin fu la prima casa d’orologeria al mondo a presentare un orologio in grado di raffigurare sul suo quadrante tutte le ore del mondo, dando inizio a quello che è stato poi il primo capitolo della storia dello sviluppo della complicazione del tempo universale, chiamato anche tempo internazionale.
E così, dopo i vari modelli sfornati negli anni, alcuni dei quali sempre con lo stesso criterio nel quadrante, ecco che nel 2013, in occasione della fiera Only Watch 2013, l’ormai prestigiosa casa d’alta orologeria Vacheron Constantin lancia il nuovo segnatempo Patrimony Traditionnelle che, grazie appunto alla tecnologia World Time, con sole 3 lancette riesce a rappresentare sul suo quandrante l’ora in ogni parte del mondo nello stesso momento.
Il nuovo Vacheron Constantin Patrimony Traditionnelle World Time si presenta con una cassa dal diametro di 42,5 mm in platino 950, distinguendosi sul mercato grazie all’elevata cura nei dettagli e gli elevati standard manifatturieri della Maison.
Il design del quadrante di questo nuovo segnatempo, è stato perfezionato e reso ancor più unico e inconfondibile dall’artista Anita Porchet, che ha contribuito alla perfetta smaltatura.
Per capire il suo meccanismo, basta sapere che il quadrante è diviso in 4 parti:
– La zona centrale è in oro e reca incise onde ricoperte da smalto translucido e opalescente, con una cartina dell’Europa ricavata con smalto a champlevè. La città di Monaco è raffigurata da un rotondo diamante.
– Una parte in metallo con i nomi delle città delle ore del mondo dipinte. Le scritte dei 24 fusi UTC sono in nero, quelle dei 13 parziali che differiscono di mezz’ora o un quarto d’ora in grigio.
– Un elemento in zaffiro con indici a 24 ore, con settore della notte in rosso e del giorno in bianco.
– Infine un anello di metallo con segnati gli indici circolari dei minuti intervallati da quelli applicati in oro 18 k in corrispondenza delle ore.
Come tutti gli altri orologi presentati alla fiera Only Watch 2013, anche il Vacheron Constantin Patrimony Traditionnelle World Time sarà battuto all’asta in un evento dedicato che si terrà il prossimo 28 settembre.

A longstanding part of the Vacheron Constantin watchmaking heritage, the World Time complication is making a noteworthy comeback to the collections from the Manufacture. The Patrimony Traditionnelle World Time model houses the new Calibre 2460WT bearing the prestigious Hallmark of Geneva. Developed and manufactured by Vacheron Constantin, this new mechanical self-winding movement is distinguished by its capacity to indicate the world’s 37 time zones, including those offset from Universal Coordinated Time (UCT) by a half – or quarter-hour – an exclusive mechanism patented by Vacheron Constantin.
The new Patrimony Traditonnelle World Time by Vacheron Constantin marks the return to the collection of a complication inextricably bound to the history of the Geneva-based manufacturer. The latter is also interwoven with the theme of travel, since Jean-Marc Vacheron and his successors have constantly circled the globe delivering their exceptional timepieces. A pioneer in the development and production of innovative watches, the Manufacture Vacheron Constantin has displayed the same approach in being resolutely open to the world at large. Created in 1755 in Geneva and able to look back over more than 255 years of uninterrupted activity, Vacheron Constantin soon began exploring the four corners of the earth. It established a presence in the United States in 1832 and in China in 1845 – well before the International Meridian Conference held in Washington in 1884 which divided the world into 24 time zones, taking the Greenwich meridian as the longitude 0 point of reference. This new approach became indispensable in keeping step with the development of international travel and of railways.
The rich history of World Time at Vacheron Constantin – In keeping with the same pioneering spirit, and driven by a wish to demonstrate that the multiple time-zone watch could be further perfected, Vacheron Constantin introduced its first timepieces endowed with an international time mechanism in 1932. This movement was the work of a brilliant Geneva watchmaker, Louis Cottier, who had imagined and developed a mechanical movement indicating the 24 time zones from 1 to 24 by means of a disc rotating around the central dial and the outer bezel bearing the names of the world’s major cities. This first Vacheron Constantin World Time “Cottier system” watch (reference 3372) enabled simultaneous read-off of the time in 31 cities around the world. It marked the start of a rich and longstanding relationship between Vacheron Constantin and the World Time complication. In 1936, Vacheron Constantin presented two new versions of its World Time model with a 31-city dial (reference 3650) and a 30-city dial (reference 3638) without Cairo. In 1937 and 1938, the Geneva-based Manufacture unveiled six table clocks with a mobile dial featuring 67 locations, including summer and winter time in Paris. From the 1940s onwards, Vacheron Constantin attributed the reference number 4414 to a world time model with a 41-city dial and a day/night division of the mobile 24-hour disc. During the 1940s and 1950s, many famous customers were captivated by this useful and ingenious mechanism, and contributed to spreading the fame of this new complication.
In 1957, Vacheron Constantin wrote a new chapter in its history of World Time watches by introducing the first World Time wristwatch, reference 6213, ordered by an Egyptian dignitary. It was the first of a long line of models incorporating this remarkable complication and that earned it an outstanding reputation among connoisseurs and collectors.
A patented new World Time calibre – Eager to make a major new contribution to the history of this complication, the Vacheron Constantin master-watchmakers and engineers have sought to create a mechanical movement capable of indicating not only the full time zones, but also the partial ones, so as to reflect the exact temporal reality in the 37 time zones. A number of countries have indeed adopted a half-hour or quarter-hour difference from UTC, and the Calibre 2460WT by Vacheron Constantin takes account of these specific characteristics. By way of example, it provides the correct time indication for Caracas, since Venezuela decided in 2007 to switch from a full time zone to a half time zone (GMT – 4:30).
The indication of the 37 time zones as proposed by Vacheron Constantin in its Patrimony Traditionnelle World Time is as complete as one could wish for. The display consists of three dials: a sapphire dial with a unique day/night shading; a metal dial with a “Lambert projector” type map; and a metal chapter ring. Beating at a frequency of 4 Hz (28,800 vibrations per hour) and endowed with a 40-hour power reserve, mechanical self-winding Calibre 2460WT drives displays of the hours, minutes, central seconds and World Time. It enables simultaneous read-off of the time in all regions of the world, along with the day/night indication provided by the central world map. All indications are adjusted via the crown, thus considerably simplifying the use of this highly technical watch. In light of these exclusive developments, a patent has been filed for the new Vacheron Constantin Calibre 2460WT bearing the prestigious Hallmark of Geneva.
Appreciable user friendliness – Despite its complex construction principles, the new mechanical World Time movement is extremely user-friendly. The wearer chooses the reference time and places it opposite the black triangle at 6 o’clock. The time in the reference location can then be read off either by the hour hand, or by the 24-hour disc, while the time in the other 36 time zones is simultaneously readable. The cities shown in black represent the full time zones, while the cities in red indicate half-hour or quarter-hour zones.
Incorporating all the signature characteristics of the collection – a slender bezel, a knurled motif on the case-back, a screw-down sapphire crystal case-back, and dauphine hands – the new Patrimony Traditionnelle World Time comes with a 42.5 mm diameter 18K pink gold case that is water-resistant to 30 metres. It is fitted with a brown alligator leather strap secured by an 18K pink gold folding clasp.
Due to the modern nature of this useful complication, along with the major innovations provided by its Calibre 2460WT, the Patrimony Traditionnelle World Time is destined to become an iconic model within the collection, and to perpetuate Vacheron Constantin’s pioneering role in the development of multiple time-zone watches.
