William Harrison Pocket Watch
This very unusual and visually appealing dial configuration is called a “pendulum watch.” The faux pendulum was intended to entertain its owner, show that the watch was running, and perhaps was a reminder of the seemingly magical technology within. The effect is caused by modifying the shape of one of the oscillating balance arms to give the appearance of a free-swinging pendulum.
The full-plate, gilded-brass movement is signed “William Harrison London” on both the dial and within a cartouche located in the center of the movement’s fully engraved back plate. The movement has four divided Egyptian pillars that are topped with decorative crests, and a divided fusee stop-work foot.
The sterling silver pair case has a maker’s mark “CC” with a coronet above likely for Christopher Cutting (Priestley). It has a split bezel. The case measures 59mm in diameter.
