The Jacob & Co. Astronomia Sky is a timepiece from the Jacob & Co. Astronomia collection. Inspired by the cosmos, its design combines intricate mechanical craftsmanship with celestial elements, showcasing a unique visual effect and exquisite watchmaking artistry.



Here is a detailed description:
Case Design: The case design resembles an astronomer's observatory, featuring a large sapphire dome at the top. A streamlined gold bezel surrounds the entire sapphire crystal, its transparency providing a vast, galactic view. The case diameter is typically around 47 mm, and the thickness is approximately 20 mm, making it relatively large and eye-catching when worn.

Movement and Functions: It is powered by the in-house JCAM11 manual-winding movement, a three-dimensional structure with a central vertical axis. The movement comprises 395 components, 42 jewels, and vibrates at a frequency of 3 Hz (21,600 vph), with a power reserve of approximately 60 hours. The movement features a rotating platform with five satellite elements, including a 1-carat Jacob Cut® diamond, a blue magnesium lacquer globe, a rotating dial, an orbital seconds hand, and a tourbillon. All these elements rotate around a central axis, completing one revolution in 20 minutes. Below the platform, the Astronomia Sky displays actual sidereal time on a meticulously crafted blue rotating base.

Appearance Decoration: The movement plates are made of mirror-polished blue titanium and engraved with constellations from the night sky, echoing the watch's cosmic theme. The center of the dial is made of aventurine, creating a starry effect, while small white ceramic spheres rotate on the dial, adding to the watch's playfulness and visual appeal.

Limitation: The Astronomia Sky is typically released in limited quantities, and its unique design and complex craftsmanship make it highly collectible.
