Por qué es dificil localizar ese tipo de Reloj?
si analizamos la historia de la marca Junghans, vemos que sobre todo se hizo muy famosa a raiz de la segunda guerra mundial, ya que uno de sus modelos, en concreto el Junghans J30E fue utilizado por los Barcos de Guerra de la marina Alemana, el reloj muy preciso, tenía una autonomía de 8 Días.
El reloj que nos muestra en la fotografía posiblemente data de los años 50, fecha en la que la firma posiblemente adopto muchas de sus maquinarias para relojes de Oficina, Despachos, Colegios...
Los relojes anteriores al año 1.936 son los clásicos relojes de pared muy al gusto de la Sociedad Alemana de la época, y los relojes de Sobre-Mesa, más a la Moda Francesa, y que incluso trascendieron a la clase media Española de la Postguerra Civil.
Posiblemente de esa fecha sea el reloj que nos muestra, y posiblemente también proceda de esas maquinarias usadas en la Postguerra de la Segunda Guerra Mundial
Junghans monto maquinarias para relojes en los Mercados Europeos de la época, y realmente ese tipo de relojes son fáciles de localizar.
La Historia de Junghans que te podemos ofrecer (Ante cualquier duda, con gusto le ofreceremos la traducción)
The German Junghans Company, started in 1860, really owes its success to American mass clock production - although clock making was well established in the Black Forest region of Germany, by about 1860, competition from the American factories had become so intense that Erhard Junghans of Schramberg decided to abandon his business of making straw hats, and concentrate on making clocks to the American system . His younger brother Xavier had been to America, and had worked in a clock factory there, and it was he who persuaded his brother to form the company Gebrüder Junghans, first to make clock accessories, and eventually complete clocks in 1866.
Xavier arranged for American machines to be shipped to Germany so that the 'modern' production methods could be used. Xavier was in charge of the case shop, Erhard managed the business activities, and a professional clockmaker was employed to supervise the making of the actual movements.
The company prospered, and after the death of Erhard Junghans in 1870, the business was carried on by his widow and sons Erhard Jr. and Arthur. Various members of the family visited America, and followed the American pattern of manufacture very closely, often with the imported tools and machinery. The style of the clocks produced was identical to the American versions, and apart from the trademark, it is often difficult to tell whether a particular movement is German or American.
The first Junghans trade mark in 1877 was an eagle with outspread wings, above a furled flag. In 1882, this was changed to a star with two eagles and a flag; in 1888, the mark was a capital 'J' in an 8-pointed star, and after 1890 this became a 5-pointed star. The Remembrance trade name was used from 1901 on their wall regulators in celebration of the wedding of Junghans’ daughter.
As well as making clocks for all price ranges, Junghans also made watches. In 1906 they became the first company to make a pocket watch with an alarm that was affordable by general public. In 1907 Oskar Junghans made the company the first company to use Radium to produce luminous dials in the clocks and later in their watches.
Like their American counterparts, most of the many thousands of clocks produced by the company were of fairly low quality, with stamped brass plates and paper dials. Because of the cheapness of production, pinions were usually lantern pinions, assembled by hand. Arthur Junghans devised a method of producing these mechanically - the pinion ends were fitted to their arbors, then placed in a metal box containing a large number of the short pieces of wire for the pinion leaves (trundles). The box was violently agitated, and eventually every pinion would have the correct number of wires in place.
In 1909, Junghans and Haller took out a joint patent (No. 4812) for a 'a clock of the kind which the movement is built into the pendulum so as to oscillate with it...'. This sort of clock became known generally as the 'Swinging Diana' clock and was very popular in the USA with many makers making versions of it.
In 1911 they modified their pocket watch to have a 7 jewel movement to improve it's accuracy. The model was available to 1924 when it was again upgraded.
The success of the company prompted other firms to follow suit, advertising 'American' clocks. One of the most famous was the Hamburg American Clock Company, formed by two of Junghans' original workers, and they became intense rivals. Eventually, after a few years of collaboration, the two companies merged in 1930 under the Junghans name. Other companies were also absorbed, including Resch Brothers (1901), Gustav Becker (1926), Lenzkirch (1928) and Thomas Haller.
About 1930, Junghans started to design wristwatches that were to be added to the product range. Four years later they had 4 different calibres on the market. In 1936, they issued their first wristwatch catalogue. Between the two world wars, Junghans rebuilt it's capacity, and even provided wristwatch movements for us in Ingersoll watches in the UK. These watches were always marked with 'Foreign' as the country of origin.
After the second world war, again Junghans, under Helmut Junghans, had to re-establish the company on the world market. The company came out with some very interesting wristwatch designs during the first few years after the war. In 1949 they showed a 14 Ligne column-wheel chronograph, in 1951 they showed their first automatic and also their first alarm wristwatches. In 1952, Junghans decided to also get into the top quality precision wristwatch market and they introduced their first Chronometer wristwatches with official rating certificates. These were very popular and sold 7,000 within the first 2 years.
In 1956, the Diehl group took made a major investment in the company and took a large shareholding. During the next 5 years over 800 patents was taken out by this company. At this time Junghans used the designer, Max Bill, to design most of their clocks and watches.
To keep ahead of the market, Junghans was one of the first companies to launch Quartz regulated clocks in 1967 with it's 'Astro Chron' and in 1970 it was one of the first with mass produced Electronic/Quartz wristwatches. Junghans stopped producing their own mechanical movements in 1976 and then used bought in movements when required.
The company was taken over by Diehl in 1985, and is one of the largest in Germany. In its latest productions, Junghans has become well known for its range of radio-controlled clocks which they launched in 1986, for their 125th anniversary
In 1990 they introduced the radio controlled wrist watch to their range. Also in this year, Diehl took over Ruhla which then came under the control of Junghans and was renamed Eurochron in 1991.
In 1999 it released it's 'Carbon' model of Radio controlled watches
Junghans and it's items. subsidiary, Eurochron, have been owned by the Egana Goldpfeil Group since 2000. By 2001, the only manufacturing done by Junghans is their radio controlled clocks and watches. Other clocks are made by Eurochron. The range still included 2 mechanical wrist watches among all the other quartz controlled
