Without these weights, the Grandfather Clock would not operate.

Each weight is different and must be properly hung from the movement (left, center, right) to ensure proper operation.

These brass gears would also make lovely steampunk jewelry charms! This movement is a model 77 and was made for Emperor Clock by Erhard Jauch Uhrenfabrik.

This is a weight and chain driven movement, rather than wind-up with a key and measures about 5" square on the brass side plates. It's marked Made in Germany (rather than West Germany) and is pen engraved with 11-89 09006, but we're dating to the later 1970s as Emperor Clock opened in 1969 and Erhard Jauch Uhrenfabrik closed in 1983.

Raising cable driven weights is accomplished through use of a crank.

Raising chain driven weights is accomplished by pulling down on the loose end of the chain.

As described within these instructions, adjustments to the pendulum to achieve accurate time keeping is easily accomplished.

The three weights provide power to the hour strike (left weight), time (center weight), and chime melody (right weight).

The product information label may be located in several locations: outside the shipping carton, back of door, back of the Grandfather Clock, top of the Grandfather Clock, inside the top back corner of the Grandfather Clock, or inside the Grandfather Clock above the back of the dial.

For easy reference in the future, take a moment to record these numbers.

Gebr Junghans Uhrenfabrik was established by Erhard Junghans with Franz Xaver in 1861 in the Black Forest, making parts for clocks.
