About the Epic X family

Epic X was launched in 2015 and was the collection that made Jacob & Co. a full watchmaking brand. It is a sporty, skeletonised watch with an X-shaped motif in the movement, a large case and often a rubber strap, and the line was later revised with chronometer-certified versions.

The catalog lists many references, including Epic X Chrono models, in steel, ceramic, gold and gold with ceramic. The open movement makes condition easy to judge, so check for dust or marks, and confirm the reference against the case material and strap.
