Rolex

According to foundation documentation, the Rolex, SA company can never be sold, nor traded on any stock market. In the Southern Hemisphere:. In fact, it is a foundation initiated and originally funded by Hans Wilsdorf and the Aegler family. So, in the Northern Hemisphere:. Rolex, SA, the current company name, is not a public corporation. With the solstices (peaks) are used as the middle of each season, as is in Jieqi and East Asian countries, the longest day of the year occurs in the middle of summer, and conversely the shortest day of the year in the middle of winter. Even the self-winding mechanical design is often replicated using standard, high-quality swiss-made movements (most often those of ETA[1]), resulting in fakes that laymen will find difficult to distinguish from the originals. In the conventional American calendar, the following dates are considered to be halfway through a season:.

By some accounts, over 75% of all fake watches produced annually are copies of Rolex designs. See below, using solstices and equinoxes as mid-days. In July 2005, in Rome, it was possible to buy a replica Datejust for 20 Euros. This is very close to the British & Irish definitions of seasons. These fakes are mainly produced in China and Taiwan — and retail anywhere from $5 to an upwards of $1000 for replicas fabricated with solid gold. The Korean, Chinese, and Japanese calendars are based on a lunisolar calendar, where the solstices and equinoxes mark the middle of each season. Like many high-priced, brand-name accessories, Rolex watches are often counterfeited and sold in markets around the world that cater to tourists. This definition is also followed in Australia.

The primary types of Rolex bracelets include the Jubilee, Oyster and the President. Conversely, for the Southern hemisphere, meterological summer begins on December 1, autumn on March 1, winter on June 1 and spring on September 1. The third line in the Rolex empire is the lesser expensive, but high quality, Tudor brand. This definition is also followed in Denmark and former USSR. Dressy designs usually fall under the sister brand called Cellini. In meteorology for the Northern hemisphere, spring begins by convention on March 1, summer on June 1, autumn on September 1 and winter on December 1. Most Rolex watches have a case design called the Oyster. The Irish calendar uses almost the same reckoning; Spring begins on February 1 / Imbolc, Summer on May 1 / Beltane, Autumn on August 1 / Lughnasadh and Winter on November 1 / Samhain.

Among modern Rolex watches are the Air-King, Datejust, GMT Master/GMT II, Submariner, Sea-Dweller, Daytona Cosmograph, Day-Date, Oyster Perpetual and Yacht-Master. Accordingly, midsummer and midwinter are, as their names suggest, the middle of summer and winter. In the early EON production Bond films, Commander Bond was seen to wear a Rolex Submariner. In the United Kingdom, the seasons are traditionally considered to begin about seven weeks earlier: spring begins on Candlemas, summer on May Day, autumn on Lammas, and winter on All Hallows. On the more glamorous side, Ian Fleming's James Bond character wore a Rolex Oyster Perpetual in the series of spy novels. By this reckoning, summer begins at summer solstice, winter at winter solstice, spring at the vernal equinox and autumn at the autumnal equinox. The Explorer and Explorer II were developed specifically for explorers who would navigate rough terrain — such as the world famous Everest Expeditions. In the United States, the seasons are often considered to begin at the astronomical solstices and equinoxes: these are sometimes known as the "astronomical seasons".

Another is the GMT Master, originally developed at the request of Pan Am Airways, to assist pilots in transcontinental flights. The date at which each season begins depends on how it is defined. This watch featured a helium release valve, co-invented with Swiss watchmaker Doxa, to dispense helium during decompression. In later winter, the first faint wash of light briefly touches the horizon (for just minutes per day), and then increases in duration and pre-dawn brightness each day until sunrise in February. Sports models include the Oyster Perpetual Sea Dweller 2000 in 1971. Eventually, for the weeks surrounding 21 December, nothing breaks the darkness. Rolex has also made a reputation in watches suitable for the extremes of deep-sea diving, aviation and mountain climbing. For a few more weeks, "day" is marked by decreasing periods of twilight.

The watch survived and tested as having kept perfect time during its descent and ascent. Eventually, it does go below the horizon, for progressively longer and longer periods each day until, around the middle of October, it disappears for the last time. Wilsdorf even went so far as to have a specially made Rolex watch attached to the side of the Trieste bathyscaphe, which went to the bottom of the Mariana Trench. In the weeks surrounding 21 June, the sun is at its highest, and it appears to circle the sky without ever going below the horizon. Rolex was also the first watch company to create a truly waterproof watch — another milestone from novelty to functional timepiece. The sky (as seen from Alert) has been showing twilight, or at least a pre-dawn glow on the horizon, for increasing hours each day, for more than a month before that first sliver of sun appears. This not only made watch-winding unnecessary, but eliminated the problem of over-winding a watch and harming its mechanism. However, mid-February is not first light.

The first self-winding Rolex watch was offered to the public in 1931, powered by an internal mechanism that used the movement of the wearer's arm. For example, at the military and weather station called Alert on the northern tip of Ellesmere Island, Canada (about 450 nautical miles or 830 km from the North Pole), the sun begins to peek above the horizon in mid-February and each day it climbs a bit higher, and stays up a bit longer; by 21 March, the sun is up for 12 hours. Although Rolex has made very few quartz models for its Oyster line, the company's engineers were instrumental in design and implementation of the technology during the early 1970s. At progressively higher latitudes, the periods of "midnight sun" (or "midday dark" for the other side of the globe) are progressively longer. Another little known fact is that Rolex participated in the development of the original quartz watch movements. What does happen is that any point north of the Arctic (or south of the Antarctic) Circle will have one period in the summer when the sun does not set, and one period in the winter when the sun does not rise. To date, Rolex still holds the record for the most certified chronometer movements in the category of wristwatches. This is true only in the immediate region of the poles themselves.

Among the company's innovations are the first self-winding watch; the first waterproof watch case; the first wristwatch with a date on the dial; the first watch to show two timezones at once; and most importantly the first watchmakers to earn the coveted chronometer certification for a wristwatch. A common misconception is that, within the Arctic and Antarctic Circles, the sun rises once in the spring and sets once in the fall; thus, the day and night are erroneously thought to last uninterrupted for 183 calendar days each. It was later changed to Montres Rolex, SA and finally Rolex, SA. Curiously, a study of temperature records over the past 300 years (David Thompson, Science, April 1995) shows that the climatic seasons, and thus the seasonal year, are governed by the anomalistic year rather than the tropical year. The company name was offically changed to the Rolex Watch Company during 1919. However, many regions (famously the northern Indian Ocean) are subject to monsoon rain and wind cycles. Wilsdorf was said to desire his watch brand's name to be easily pronouncable in any language. In the tropics, there is no noticeable change in the amount of sunlight.

It is thought this change was part of a drive to popularize wristwatches, which at the time were still considered a novelty largely for women (pocket watches were more common). When it is summer in the Northern hemisphere, it is winter in the Southern hemisphere, and vice versa, and when it is spring in the Northern hemisphere it is autumn in the Southern hemisphere, and vice versa. The company name Rolex was officially registered on 15 November 1915. The cycle of seasons in the polar and temperate zones of one hemisphere is opposite to that in the other. From that time to the present, Rolex has been headquartered in Geneva, Switzerland, though the company owns facilities in other cities (Bienne, etc) and continents (North America, Asia, Australia, etc). The result is that the South Pole is consistently colder during the southern winter than the North Pole during the northern winter. Wilsdorf wanted his watches to be affordable, but taxes and export duties on the case metals (silver and gold) were driving costs up. The North Pole is in the Arctic Ocean, and thus its temperature extremes are buffered by the presence of all that water.

The Wilsdorf & Davis company moved out of Great Britain in 1912. For example, the South Pole is in the middle of the continent of Antarctica, and therefore a considerable distance from the moderating influence of the southern oceans. One story, which was never confirmed by Wilsdorf, is that the word "Rolex" came from the French phrase horlogerie exquise, meaning exquisite watch industry. These effects vary with latitude, and with proximity to bodies of water. The word was made up, but its origin is obscure. In the temperate and polar regions, seasons are marked by changes in the amount of sunlight, which in turn often cause cycles of dormancy in plants and hibernation in animals. Hans Wilsdorf registered the trademark name "Rolex" in La Chaux-de-Fonds, Switzerland during 1908. Seasonal weather fluctuations also depend on factors such as proximity to oceans or other large bodies of water, currents in those oceans, El Niño/ENSO and other oceanic cycles, and prevailing winds.

The earliest watches from the firm of Wilsdorf and Davis are usually marked "W&D" – inside the caseback only. 2 and Month ranges of seasons (below)). These early wristwatches were then sold to jewellers, who then put their own names on the dial. At any given time, regardless of season, the northern and southern hemispheres experience opposite seasons (see Fig. They originally imported Hermann Aegler's Swiss movements to England and placed them in quality cases made by Dennison and others. This exposure alternates as the Earth revolves in its orbit. Wilsdorf & Davis was the original name of what later became the Rolex Watch Company. 1).

Contrary to popular belief, Hans Wilsdorf was neither Swiss, nor a watchmaker. Thus, at any given time during the summer or winter, one part of the planet is more directly exposed to the rays of the Sun (see Fig. Alfred Davis. The cause of the seasons is the fact that the Earth's axis is not perpendicular to its orbital plane; it deviates by an angle of approximately 23.5 degrees of arc. Hans Wilsdorf and his brother-in-law, Mr. . The Rolex, SA company was founded in 1905 by Mr. In some parts of the world, special "seasons" are loosely defined based upon natural events such as a hurricane season, tornado season, or wildfire season.
