Jacob & Co. Astronomia Tourbillon
This article provides a comprehensive analysis of the replica Jacob & Co. Astronomia Tourbillon, including its background, core design, classic/popular models, and technical highlights, perfectly catering to your exploration of the watch’s story and details.
Background and Inspiration
Founder Jacob Arabo has a long-standing passion for celestial bodies and space exploration. He initiated concept development in 2014 and officially launched the first model in 2015, aiming to condense the laws of astrophysics into a mechanical solar system on the wrist. Completely breaking away from the traditional planar tourbillon framework, it utilizes a multi-axis rotation + satellite-like four-arm structure to create an “observatory on the wrist,” a highly performative masterpiece of 21st-century haute horlogerie.
Core Design and Mechanical Structure
Four-Arm Satellite System: The iconic four suspended arms each house a three-axis flying tourbillon, a diamond-encrusted “moon,” a blue-painted “Earth,” and hour/minute sub-dials; early versions completed one rotation every 20 minutes, later iterations reduced to 10 minutes, then 5 minutes, and the latest Revolution series achieves a full rotation in 1 minute.
Multi-Axis Tourbillon Breakthrough: The initial generation achieved a three-axis flying tourbillon (each axis completing rotation in 60s, 18s, and 15s respectively); in 2025, the world’s first four-axis tourbillon (Astronomia Revolution Four-Axis) will be launched, with rotation speeds of 60s, 18s, 15s, and 60s for each axis, coupled with a high-frequency constant force mechanism to ensure accuracy. fake watches for sale
Transparent Case and Starry Sky Dial: The case resembles an observatory dome, featuring a large domed sapphire crystal (fully transparent top, sides, and case back); often uses aventurine as the dial to simulate the night sky; materials are mostly 18K rose gold and white gold, with some jewelry models pavé-set with baguette diamonds (Jacob & Co.).
Manual Winding Movement: A highly complex in-house movement with over 300 parts, requiring extremely high precision in assembly and adjustment; power reserve is typically around 48 hours.
Size and Water Resistance: Mainstream sizes are 50mm (classic model) and 47mm (Revolution series); water resistant to 30 meters, primarily for dress/collection, not suitable for strenuous exercise.best fake watch

Differentiating itself from other brands in the same category
Unlike Richard Mille’s lightweight, high-tech materials and Greubel Forsey’s understated precision, Jacob & Co.’s Astronomia emphasizes mechanical performance and visual impact, using “celestial motion” as its core narrative. It is a combination of watchmaking and art installation, suitable for collectors who seek uniqueness and are willing to showcase their individuality on their wrists.
