Product Details
The Jacob & Co Epic X is a modern evolution of one of the most traditional forms of watchmaking. The open-worked, or "skeletonized" timepiece allows the movement to be visible both through the dial and the back of the watch, with as much metal removed as possible without compromising functionality. The goal of the watchmaker crafting an open-worked watch is to achieve the highest level of transparency possible; the challenging combination of visual lightness with structural integrity.
The Epic X case is bold and elegant, yet robust, so it can truly accompany you through your day, to the office, out for a casual dinner or even to an elegant party.
