Jacob & Co. Astronomical Triaxial Gravity Tourbillon

Jacob & Co. Astronomia Triple Axis Gravitational Tourbillon - A replica watches online with a stunning starry panorama and a triple-axis tourbillon. In 2014, the brand has launched an astronomical tourbillon equipped with a three-axis tourbillon. This year, it was decided to add a three-dimensional sidereal time indicator to the astronomical combination, adjacent to the sky chart and day/night indicator. The dial of the astronomical sky, made in the form of a firmament, makes one revolution at intervals equal to a sidereal year (a sidereal year is the time the Earth takes to make one revolution around the sun relative to the star). Made of titanium, for completeness, it is decorated with 18-carat white gold stars and hand-engraved zodiac signs.

Just below the dial is an indicator, a map of the stars in the northern hemisphere. The sub-dial makes one revolution in an interval equal to one sidereal day (one revolution of the Earth on its axis takes approximately 23.560916 hours).

The dial is covered with a glass hemisphere, under which the four-axis modular design is evident in all the details. At the center of the structure is a hand-carved painted titanium sphere. Protected by a tinted sapphire glass dome, the ball rotates on its own axis, symbolizing the change of day and night. The spin rate of the ball is one full revolution every 20 minutes.Jacob & Co.

The modular design itself rotates at the same speed, with a three-axis tourbillon at one end. The speed of rotation of the tourbillon on the different axes is as follows: 60 seconds around the first axis, 5 minutes around the second axis, and 20 minutes around the third axis.

The upper part of this space composition is occupied by a subdial with hour and minute indications. Thanks to the differential system, the hour markers are always placed vertically, which allows the user to read the hour indication accurately in the usual clockwise direction.

Earth's third "satellite" is an unusual watch ensemble, the orbital seconds hand - a skeletonized titanium wheel that completes one revolution on its axis in 60 seconds. The fourth is an orange Jacob Cut sapphire with 288 facets that wraps around its axis in 60 seconds and the dial in 20 minutes.replica Grand Seiko Sport Watches

This micromechanical marvel can be handled by a special ring mounted on the back of the watch. The first ring is designed to set the time and day/night indicator, the second to run the movement. You can adjust the sidereal time and the view of the star map using the gears, which are also located on the back of the model.

The in-house calibre JCAM11 with manual winding is responsible for coordinating all the functions of this watch. The 40mm-diameter movement consists of 395 titanium parts mounted on 42 jewels, with a balance frequency of 21,600 vibrations per hour and a power reserve of 60 hours.

The Astronomia Sky case is made of 18k rose gold and has a diameter of 47mm. On the front, the case is covered with a domed sapphire crystal. The case back is also rose gold. The case is water resistant to 30 meters. The watch comes on an alligator leather strap with a rose gold folding clasp. This model is limited to 18 piece numbers.replica Breitling SUPER CHRONOMAT Watches
