5 October 2000 the company introduced the world Patek Philippe pocket watch "Star caliber 2000", one of the most sophisticated mechanical watches of all time. Hardly six months have elapsed, the Geneva plant fired into being the new hours "Grand Complication", but now in the form of wrist watches. "Sky Moon Tourbillon", model 5002, is the most complicated wrist watch, ever, and is the first model of bilateral wrist watch, which represent a complete picture of the night the vault of heaven on the back side. This new masterpiece reflects the natural movement of the stars, the orbit of the Moon, phases of the moon, as well as hours and minutes of stellar time.
Symphony features
So as with the development of astronomical clock "Star caliber 2000 ", the purpose of Patek Philippe in the development of a model" Sky Moon Tourbillon "was not in the recruitment of an increasing number of features combined in one clockwork. The real aim is to conclude in a small body watches the most remarkable and rare functional mechanisms: perpetual calendar with retrograde date hand, minute repeater, turbiyona, stellar display time and display the night sky with the motion of stars, the orbit and phases of the moon. This creation has become an excellent piece of art and technology, because the display card sky (as it is seen from the northern or southern hemisphere) requires a minimum of space in order to demonstrate the motion of stars quite clearly. The solution chosen by Patek Philippe, was taken from the pocket astronomical clock, made by a company - a moving celestial body diagram on the back of the clock. The mechanical module, created by Patek Philippe for hours "Star caliber 2000, was again redesigned specifically for the model of" Sky Moon Tourbillon ", which received a Swiss patent CH 688 171 B5. Minute repeater as a heraldic symbol of the Third Millennium Acoustic indicator of an hour, a quarter hours and minutes (minute repeater), of course, remains one of the most attractive features, which may be a wristwatch. It is necessary to press the lever on the left side of body clock, as the repeater first starts to beat the number of hours of low tone, then a double shot of low tone - a quarter of an hour, and finally, the single high tone strikes the number of minutes that have elapsed after the last quarter of an hour. Musical arrangement in this model, hours of "Sky Moon Tourbillon" is executed in an unusual and remarkable manner.
A small amount of modern building watches extremely difficult task is to reproduce a clean and rich timbre of the sound. Several years ago, after intensive searches in conjunction with specialists in the field of acoustic and steel, Swiss Federal Institute of Technology Lausanne city, the company Patek Philippe was able to develop a special alloy for the gong, which could produce a net resonant sound. Currently, the formula of the alloy goes further adjustments. The sound of a minute repeater hours "Sky Moon Tourbillion" called "church bells", as he recalls the battle chime in cathedrals.
Turbiyonu not afraid of the earth's gravity force
Old Vintage ClocksAny mechanical clock, equipped with balance beam, are the so-called positional error, if they are kept in an upright position as the center of gravity of the spring actuator deviates from the axis of rotation. This error can be offset mechanism turbiyona, which is a rotating suspension, which includes the anchor mechanism and the spring balance beam, and which usually turns around its axis once a minute. This rotary motion of the center of gravity of the spring actuator also moves around the axis once per minute, and thus compensates for positional errors. The model 5002 hours turbiyon, balance beam and fourth gear are on the same axis. This configuration is the most difficult to execute, but the best use of the principles of the mechanism turbiyona. Turbiyon Hours 5002 is truly amazing: made of steel tiny device is of not less than 69 parts, with the weight of barely more than 0.3 grams - this shows how much filigree and microscopically small part.
perpetual calendar with retrograde date hand
perpetual calendar clock Patek Philippe has a legendary history. The model "Sky Moon Tourbillon" added to this calendar retrograde arrow. It displays the date in the position of the arc equal to 270 degrees on the dial. Every day, the arrow moves the date forward by one position and at the end of the month (28, 28, 30 or 31 number) is automatically moved back to the first day of the month. Unlike conventional solutions, this mechanism is based on the retrograde date patented mechanism gear with dogs, which provides extremely high accuracy, regardless of the location of the hand. At a time when the needle dates back to the beginning of the end of the scale, the mechanism prevents the undesirable jump in second or third number. Thus, the beginning of each new month of the date of the arrow will inevitably meet in the "1".
remaining indicators perpetual calendar has four additional clock face: the day of the week - in the 9 o'clock position, "leap year" - the situation in 12 hours , a month - in the "3 hours" and the lunar calendar - in the "6 o'clock". All indicators are synchronized and do not need to be adjusted to the year 2100, provided that the arrangement of hours will keep podzavoditsya.
Astronomical functions on the back of the clock
At the back of the clock "Sky Moon Tourbillon" is something that is extremely unusual for the watches. This is a map of the northern sky (or on request from the southern) hemisphere, which rotates counter-clockwise under the sapphire glass back cover of hours, which shows the movement of stars and the moon, meridian passage of Sirius and moon, as well as arriving and departing phase of the moon. In addition, the two arrows emanating from the center show sidereal time on the 24 hour scale. Elliptical contour shows the portion of the sky, which could be foreseeable to a certain location. Fascinating presentation of the breath provides a unique mechanism (patent Patek Philippe).
Star clock mechanism "Sky Moon Tourbillon" Patek Philippe production company has reached unparalleled heights of accuracy in the mapping of astronomical targets.
moon day is considered period of time that flows between two successive moon passing through a particular meridian. The average duration of 24 hours, 50 minutes and 28,328 seconds. Moon (the time between two full lunami) lasts an average of 29 days, 12 hours, 44 minutes and 2, 82 seconds. Star day is considered the period between two successive passage of a particular star (like Sirius), through a specific meridian. Its duration is an average of 23 hours, 56 minutes, and 4.09892 seconds in units of solar time. Geographical longitude of specific locations can be calculated using the sidereal time.
there are basically the difference of deviations from the true solar time, affect the accuracy of astronomical targets in relation to each other. Some of these relationships negatively affect the accuracy of the testimony phase of the moon relative starry day, while others - the accuracy of the star of the day in relation to the lunar cycle. In general, there are 25 trillion possible combinations of varying relationships. This unimaginable number of combinations company Patek Philippe has been the best option, which allows you to achieve the lowest error for all indices. The result of theoretical calculations has surpassed all expectations:
For lunar day error is 0.05 seconds per day, 18385 seconds in a year or 30 minutes and 38.5 seconds per century, for the star of the day deviation equals 0088 seconds for the star day, 32,139 seconds in a year or 53 minutes and 33.9 seconds per century, and for lunar phase error is 6.51 seconds for a period of one lunoobrazovaniya.
Masterpiece perfect
mechanism with manual factory progress is a masterpiece of precision engineering, which consists of 686 individual parts, each of which is done manually. Facets of polished steel parts and each denticle of each gear mechanism polished manually grinding disk of solid tree. This perfection is not an end. Polishing reduces friction at the ground contact of teeth shesterenok that significantly improves the accuracy of the testimony of time and durability, which the company and Patek Philippe watches are truly legendary reputation. Fee and perpetual calendar module is finished on both sides of a special method of engraving, which is known as the "circular method of granulation. Ears for hours of bracelet decorated using engraving, known as the "Geneva filigree. Due to the extremely labor-intensive production processes and operations required for testing the accuracy of the watch, for the creation of each mechanism is required for several months. The result is a perfect and precise engineering product worthy of the Geneva brand on his body - the highest official mark of quality which is attributable to mechanical clock. Hours of "Sky Moon Tourbillon", model 5002, equipped with certified chronometer COSC, as well as other watches Patek Philippe, a mechanism turbiyona.
