Product Details
Jacob & Co. is on a mission to explore every existing horological complication, and to create new functionalities. One of the rarest and most prized ones is the automaton. Animated sequences of figurines on the dial is a classic endeavor in clock-making, yet infinitely more complex in wristwatch format. Jacob & Co. has modernized the concept and set it in an intense universe. Oil Pump is a three-dimensional, animated depiction of an oil well with watchmaking parts.
The rig itself is the star in Oil Pump. It bobs up and down and recreates the way an actual derrick works. It's coupled with a drill-head, symbolized by a downward-facing twin-axis tourbillon. Around them, Jacob & Co. recreated the physical environment of an oil well, complete with barrel, piping and manifold. Oil Pump is a large format expression of creativity. A demonstration of horological expertise. A showcase of Jacob & Co.'s unique ability to craft meaningful narratives.
