The X-ray technological examinations by Fraunhofer EZRT revealed that the movement dates back to Peter Henlein's time by type, but the watch itself was assembled only in the 19th century. Thus, it is a "compilation" of older and newer components.

Objective

Clarify the actual age of the clock through accurate nondestructive evaluation of its internal components.

 

The Henlein pomander watch is a mechanical clock with a mainspring and fusee, housed in a box-shaped case.

On the inside lid of the clock, there is a forged signature of Nuremberg clockmaker Peter Henlein together with the year 1510. If the engraved date were correct, the Henlein clock would be the oldest small-format portable pocket watch in the world.

X-rays by Fraunhofer EZRT revealed that the clockwork mechanism dates back to Peter Henlein’s time, but the clock itself wasn’t added until the 19th century. This makes it a “compilation” of older and newer components.
