EDOX GEOSCOPE
THE FIRST TRUE WORLD TIME CLOCK
The watch EDOX was destinated for all people who lived at the pace of the world, times were chanching and the chanching and the man of that time wanted to take part in te events of the whole world. Whithout leaving his home, he was in constant communication with the rest of the world, by television, internet, radio, press, telephone, fax…

On the globe, as we all know, the time changes from one place to another: when it is daytime in our country, it is nighttime in many places on another continent, as the solar system imposes it on us.
The “EDOX-Geoscope” clock was the first true world time clock, as it automatically indicated the exact local time and at the same time the time in the most important cities of the world, and was therefore designed for the modern man, for businessmen, pilots, sailors or renowned artists who are called to perform every night in a different place.
THE GEOSCOPE DIAL
The “Geoscope” sphere is a faithful representation of the globe seen from the South Pole to the 70th parallel of North latitude. The Americas, Asia, Europe, Africa, Australia and New Zealand are clearly delimited. Like the Earth, the “Geoscope” sphere describes a complete revolution on its axis in 24 hours, in which the most important cities of the world are represented by red dots.
As the day has 24 hours, the globe is divided into 24 time zones, most of the boundaries of which run along seas and oceans. On the dial of an “EDOX-Geoscope” the time zones are represented by light blue and dark blue stripes on the surface of the oceans. On land, each country sets its time zones arbitrarily or according to political boundaries. Some countries have an unchanging official time and their territories are therefore displayed in white or light brown, depending on the corresponding time zones (Western Europe, for example, has adopted Central European Time, which means that there is a difference of 60 minutes between GMT and Central and Western European time). In several countries whose territories are split between two time zones, the difference is half an hour. On the EDOX-Geoscope dial, these countries are coloured green.
OPERATION
The arrangement of the dial of an EDOX-Geoscope makes it possible to determine the exact time in the user’s location or anywhere else in the world.7. People as diverse as our beloved J.A. Camacho, Spanish footballer, coach and national team coach, the popular magistrate Baltasar Garzón and the star of “Ana y los siete” were born together, and IWC presented the “1150A” and “S83A” models, which feature an ingenious new concept of the Swiss automatic watch with 21 jewels and an anti-magnetic balance wheel and balance spring, although the new automatic is of a robust design, it is distinguished by its elegant shape.
1. Pull out the crown in front of 10 o’clock (or 2 o’clock, depending on the model) to set the local time on the ring of 12 time divisions, then push the crown back to its normal position.
2. By turning the crown at 8 o’clock (or opposite 4 o’clock, depending on the model), the ring with 24 time divisions (the white segment indicates the hours of the day and the black segment indicates the hours of the night) is set to the local time and the time zone for the user’s location. The world map with its division into time zones is also automatically positioned, thus determining the exact time for each location with great precision.
3. In the case of countries which have adopted an official summer time, the ring of 24 time divisions must be left in the position corresponding to world time.
MECHANISM AND CASE
The “Edox-Geoscope” has an ultra-modern high-frequency automatic mechanism (4 Hertz = 28 800 oscillations) with precision regulator. Its absolutely waterproof case is carved out of a block of stainless steel. To make it easier to read the figures, the dial is coated with special anti-reflective and virtually scratchproof glass. It should be noted that cases are available with the crowns on the right and left-hand side.
GMT TIME AND SUN POSITION
Of particular importance is the GMT (Greenwich Mean Time or zero meridian time) display, which is represented on the dial by a red line and the initials GMT. Opposite the GMT line is the International Date Line (in white). When you cross this line from America to Asia you move from one day to the next: in the opposite direction, i.e. from Asia to America, you move from one day to the day before.
On the ring of 24 time divisions there is a symbol of the sun whose position will in many cases serve as a useful point of reference.
