JACOB & CO ASTRONOMIA SKY

To truly appreciate Jacob and Co. 's latest wrist watch, one must first realize its predecessor. “After the 1st version [Astronomia], we decided we wanted to connect the watch for the stars, ” explains Luca Soprana, watch development expert at Jacob & Co. who launched the part in 2014. This tremendously complicated watch features a moment display and a tourbillon, together with representations of the Earth and also Moon spinning on spokes around a central axis : all visible under a great expansive sapphire dome. This timepiece bucked the trend among fresh timepieces, and while attracting stalwarts from the Swiss watchmaking market, it also encountered some critics in its early days.

Jacob and Co. quelled a lot of judgments with its new Astronomia Sky. It incorporates a sidereal real-time display that trails the movement of the megastars with zodiac indications. Number of features stand out more than the sidereal time complication, a feature that only one of the most complicated and prestigious watches have ever attempted. "The reference in these displays will be the planar sky map made by Patek Philippe and Vacheron Constantin, " Soprana mentioned. Planetarium, where all the actors and planets are re-writing. "

The star guide of the Astronomia Sky is found below the inverted dome on the movement, with moving ovals indicating stars above the lat. of Geneva. The cupola rotates imperceptibly, about a single degree per day, to are the reason for Earth's orbit around the sun, differentiating a sidereal day (23 hours, 56 minutes, several. 1 seconds) from a solar power day. Soprana had to generate special planetary gears to be able to accurately represent large decelerations, but it was Arabo's horological industry method, which Soprana claims allowed him to create a superstar dome that reminded the dog of the work of the plumber Giotto. “The great thing concerning working with Jacob, ” he or she says, “is that he has not a watchmaker at all. He has concerned with the aesthetic top quality of the piece and requirements things that a technician could not ask for. He demands an entirely different approach.
