Jacob & Co Astronomia Solar replica Watch



This article provides a comprehensive analysis of the Jacob & Co. Astronomia Solar watch series, a landmark piece that deeply integrates astrophysics with haute horlogerie. First launched in 2017, it has since spawned several limited-edition versions.

Design Inspiration and Core Concept

Inspired by founder Jacob Arabo's long-standing fascination with celestial bodies and space exploration, the watch aims to recreate the rhythm of the solar system on the wrist through a purely mechanical structure. At the center, a 288-faceted Jacob-Cut citrine (approximately 1.5 carats) symbolizes the sun; the eight planets surrounding it are represented by different gemstone cabochons (such as white granite Mercury, rhodonite Venus, and jasper Mars); and a hand-painted magnesium alloy globe rotates every minute. The entire central platform completes a 360° clockwise rotation every 10 minutes, while the base simultaneously rotates counter-clockwise in a 10-minute cycle, creating a zero-gravity visual spectacle.

Jacob & Co. Core Movement and Complications

Equipped with the JCAM19 manual-winding movement, comprising 447 parts, 43 jewels, a frequency of 4Hz (28,800 vph), and a 48-hour power reserve. Key functions include:

A one-minute flying tourbillon, creating a double-axis effect with the rotation of the platform; An off-center hour and minute dial with a patented differential, ensuring the dial remains vertically readable regardless of platform rotation; A globe that rotates once every 60 seconds and revolves around the sun once every 10 minutes.

Wearing and Collection

This watch is an absolute work of art and a mechanical marvel, suitable for formal occasions or high-end watch events. Due to its relatively large size (21mm thick), it is not particularly comfortable for daily commuting. As a limited edition, its complex mechanical structure and unique cosmic-themed design give it significant collectible value, but maintenance costs are high; official after-sales service from the brand is recommended.
