''Lost Knowledge'' in Astrolabium watch!

A talented independent watchmaker Christiaan van der Klaauw began its steps in the watch industry in 1974, began the creation of his unique and highly complex time meter. A passion for astronomy, Christiaan embodies his passion in watches, which have acquired astronomical specific. It is no accident that the master is not deprived of the attention of such astronomical device as the astrolabe, artfully placing it on a watch.

Astrolabe is the ingeniousAstrolabium mechanical device for determination of time by the Sun and stars. In Greek "astrolabe" means "taking the star." Throughout history there have been developed various types of this tool, but the most famous is astrolabe, in which a starry sky is displayed in the form of a rotating disk. About the principles of this method of projection there is a mention, dating back 150 years before Christ. Astrolabe shows a picture of the starry sky in a certain place at a certain moment. Firmament is indicated by symbols in a way that is easy to read. Astrolabe is also widely used by astrologers, who used it to determine the position of the planets to create horoscopes (before the ephemeris). It is believed that the creator of an astrolabe is a Hipparchus - the greatest Greek astronomer, although some scientists are inclined to consider the creator of the astrolabe Ptolemy. Usually, the astrolabe, the diameter of which was about 15 inches, is made of brass. The history of the astrolabe began over 2000 years ago, when, according to some, Ptolemy laid the foundations of the astrolabe in writing form. Astrolabe first appeared in Greece. It is known that in 200 BC. the projection of astrolabe was extensively studied by the Greeks. First mention of the device, which looked like the astrolabe, can be found in works of Mark Palliona Vitruvius (26 BC.). However, knowledge of the astrolabe was lost, and only thanks to Arab sources astrolabe has been restored. The astrolabe was introduced to Europe through Spain in the 12th century by the Moors of Andalusia and was soon restored by the surviving Arabic manuscripts. For over 500 years, the astrolabe was the most important astronomical instrument until the middle of the 17th - century the role of astrolabe was assigned by other tools.

CK astrolabium CKAL1166 watchAstrolabium watch is a true masterpiece and pinnacle of human thought and skill. In creation of Astrolabium watch a skilled craftsman Christiaan van der Klaauw drew inspiration from the age-old tools - astrolabe. Flawless and colorful design, high quality materials and, most importantly, the ingenious mechanism make this watch masterpiece in a desired attribute. Astrolabium watch has already gained a status of legendary watch. This watch is able to "tell" about many things, rather than just the time. The watch indicates the date, the local solar time, the position of the Sun and Moon on the ecliptic, position of descending and ascending node of the lunar orbit (pet dragon), and eclipses of the Sun and Moon. On the dial, the time and place where the sun sets, is marked in the intersection of the solar hand and the outer periphery of the ecliptic. In addition to local solar time, the solar hand indicates the current date. The Moon, as the Sun moves along the ecliptic. The intersection point of the lunar hand with the outer circumference of the ecliptic ring indicates the position of the Moon on its orbit of Earth. If the point of intersection was on the western horizon, so at the moment the Moon is rising. The distance between the Moon and the Sun indicates the phase of the moon at the moment: if the Sun and the Moon is completely covered - this is a new Moon. If they are diametrically opposed to each other - this is a full Moon. The third hand is a "Dragon's hand." The Moon and Sun are in the same plane of the ecliptic. However, the Moon moves around the earth at an angle of 5 ˚ to the ecliptic. The Moon has two points of intersection with the plane of the ecliptic. Intersection points, also called nodes, are marked with head and tail of "dragon hand." When the moon is full and it is on one of its nodes, so it is an eclipse of the Moon. When the Moon and the Sun are completely intersected at one of nodes, so it is an eclipse of the Sun.

The model of watch - astrolabe CK astrolabium CKAL1166 is a unique and unrepeatable creation. The flawless round case with diameter of 40 mm is made of pink gold. The tri-color dial with black indexes and blue blued hands, and case back is covered with durable sapphire crystal with anti-reflective coating. The clock is provided by a modified self-winding CK 1198 with built-in astrolabe. The blue strap is made of alligator leather and is equipped with a secure clasp also in rose gold. The watch - astrolabe by Christiaan van de Klauw – is a real find for collectors.
