Product Details
When launched back in 2015, the original Epic X collection was instrumental in making Jacob & Co. the full-fledged watchmaking brand it is today. A complete work of watchmaking, the epic X V2 was ahead of the trends that went on to define the sporty, high watchmaking, skeleton watch as a hero of the 2020s. It later became the blueprint for the Epic X Chrono and Epic X Tourbillon, and this second generation design.
When released, the Jacob & Co Epic X was also a uniquely designed piece. It was one of the rare instances where the inside and outside of a watch were in actual symbiosis. The X figure that gave the collection its name is to be found on its pairs of lugs. They're interconnected through the vertical bridges of the skeleton movement, creating a continuous shape throughout the entire piece.
