Singer J Balvin spotted wearing a Jacob & Co

J Balvin, the Colombian reggaeton artist whose visual identity is as carefully curated as his music, was recently spotted with one of the most mechanically extravagant timepieces available on the market: the Jacob & Co Astronomia Tourbillon in 18k rose gold. The sighting, captured with the watch prominently displayed on his tattooed wrist, places Balvin firmly among a small global circle of collectors who treat haute horology as wearable sculpture.

The Jacob & Co Astronomia Tourbillon — reference AT100.40.AA.SD.A — measures a commanding 50mm in diameter and houses one of the most elaborate movements ever contained in a wristwatch. The caliber JCAM09 is a manually wound, triple-axis tourbillon that rotates on three independent axes: 60 seconds, 10 minutes, and 20 minutes per revolution. The movement operates at 18,000 vph and offers a 60-hour power reserve. Four arms extend from the central axis, each carrying a distinct element: the tourbillon cage, a differential gear, a time display sub-dial with Roman numerals and blue steel hands, and the signature Earth-Moon complication.

The dial itself is a 25mm-high domed sapphire crystal over a deep blue aventurine field designed to replicate the night sky. The Earth globe rotates on its own axis once every 60 seconds, while the Moon is represented by a 288-facet, one-carat diamond — a detail that straddles the boundary between watchmaking and jewelry. The 18k rose gold case amplifies the warm tonal contrast against the midnight blue aventurine.

From a collector's perspective, the Astronomia Tourbillon occupies a rarefied tier. Jacob & Co produces this reference in extremely limited numbers, and ownership signals an appetite for maximalist complications over conventional horological restraint. It sits alongside pieces from Richard Mille and MB&F in the category of watches that reject subtlety by design. The secondary market reflects this: verified examples rarely surface, and when they do, premiums above retail are standard.

J Balvin's affinity for statement pieces — he has previously been spotted with Richard Mille and Audemars Piguet — makes the Astronomia Tourbillon a coherent addition to his collection. At a retail price north of $500,000, this is not an impulse purchase; it is a deliberate declaration.
