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. 

William Harrison apprenticed to Richard Blundell from 1692/93 to 1699 (Loomes). This watch was made circa 1702.

Having both the balance and fast-slow regulator on the front of the watch movement freed up the entire back plate to be artistically engraved.

Most false pendulum watches have the automation on the back on the watch, a design that utilized a standard verge and fusee ébauche and was therefore relatively easy to make. The downside was that the owner had to open both cases and swing out the movement to see it. A particularly nice example of this configuration is by Jacobus Vand Hegge. In contrast, watches having a dial-facing pendulum required that the balance and regulator be located under the dial and therefore utilized an ébauche specifically designed for this purpose. It was therefore more expensive to make (and also to repair) and is seldom seen

Notice that the fast-slow regulator is set through the dial, located next to the number 4. The catch to release the movement from the case is located next to the number 7.

Early English Hallmarks

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.
