Jacob & Co. Introduces Minimalist Astronomia Régulateur Watch
The Astronomia Régulateur reinterprets Jacob & Co.’s iconic Astronomia line with a minimalist aesthetic, featuring a 43 mm rose‑gold case and a sleek black dial. Separate hour, minute, and seconds sub‑dials orbit the face, driven by a high‑speed carrier that completes a revolution every minute, while a double‑axis flying tourbillon and a large seconds disc rotate in opposite directions. Powered by twin mainspring barrels, the movement employs a rapid remontoir that fires six times per second, delivering precise torque to the escapement and ensuring consistent balance amplitude despite the intense energy demands. Technical specifications include a manual‑winding JCAM56 movement with a 28‑hour power reserve, 21,600 vibrations per hour (3 Hz), and water resistance to 30 m. The watch is limited to 18 pieces, each presented in vibrant color versions originally, now refined to an understated black dial paired with an alligator leather strap and a rose‑gold folding buckle. A differential mechanism keeps the hour and minute displays upright as they orbit, combining cutting‑edge engineering with refined wearability.
Buying Time Analysis: The Astronomia Régulateur marks a pivotal evolution for Jacob & Co., showcasing groundbreaking mechanical innovation and a minimalist aesthetic that redefines high‑horology while highlighting the brand’s commitment to pushing the limits of kinetic watch design.
