Edward Korfhage and Son, Buer, Germany, c. 1950's.

Three train with hour and quarter hour count wheel strike. Combined cast iron flat bed with plate and spacer construction. Graham deadbeat escapement with adjustable pallets. Planet and ring gear maintaining power on all three trains. Movement is equipped with a 60 second, differential type, gravity driven train remontoire and is designed to be both electrically and manually wound. 38"w x 55"h x 30"d. For more information on remontoire see Wagner.

Based strictly on a manufacturing level, this is one of the more 'over-engineered' clocks I've seen. The Vulliamy style bushings have very long journals. The fit and gauge of the wheel works are robust. Frame includes cabriole legs, a style favored by several manufacturers in the United States, but quite uncommon in Europe.

The normal mode of operation was for the clock to be periodically wound by an electric motor. However the design allows for manual winding at any time. Built in the 1950's this clock represents the end of the era of mechanical tower clock movements. In fact at the time of it's manufacture it was already obsolete. Movements that were strictly electrically wound, or more commonly, dials that were purely electrically controlled via servo motors were already becoming common. Within a decade the use of a mechanical movement to power tower clock dials would be extinct. It's amazing that at the end of the mechanical era this company chose to produce such a complex and surely expensive 'tour de force' of mechanical engineering. This is an incredibly complex clock with 579 individual parts - 50% more than that of a normal three train tower clock. A similar sized, manually wound, three train version can be seen here.

The Korfhage machine tool company is still in business today but does not manufacture clocks.
