Is This The World’s Oldest Watch? A Peter Henlein Mystery From 1505

Posted by Magnus Ejlskov on

It’s a story that could have come out of a thriller novel, and it’s about one of the oldest known watches in the world, which has is thought to have been made in 1505 by Peter Henlein. .

This is not the famed Nuremberg Egg (Nürnberger Ei) that was previously thought to be Henlein’s first confirmed work. This watch we are talking about here has been dubbed the Pomander Watch (Bisamapfeluhr) and it was confirmed as the oldest known watch at a press conference that took place on December 2nd 2014 in Nuremberg, Germany.

The committee included Hermann Grieb (of Grieb & Benzinger, most likely the foremost vintage watch expert in Germany); Dr. Peter Mikitisin, physicist, appraiser and specialist for industrial computer tomography; Frank Fox, expert for micro and macro photography; and Dr. Georg von Tardy, horological specialist for metallurgy and metal processing.


This apple-shaped watch (or small portable clock) first surfaced in 1987 thanks to a watchmaker apprentice, who found it at a London flea market in a box filled with spare parts and metal bits. He had bought the entire box full of items for 10 pounds and only discovered the unusual timepiece among the objects later.

In 2002 he sold it. After a specialist for renaissance timepieces declared it a forgery or a copy of the original, the next owner sold it too. The nagging question of its authenticity remained with its latest (anonymous) owner, though, causing him to engage in further research.

And it was a good thing, too: as it turns out, he was in possession of what may be one of the world’s earliest known portable timepieces.


The evidence of the oldest watch

The shape of the case was attributed to Henlein through documentation of previous work. The copper and gold plating of the case was examined using a laser micro spectral analysis, which provided the time period.

Inside the case, under the dial, an engraving was found displaying the letters M, D, V, P, H, N. This has been interpreted as “1505” (MDV in Roman numerals) and “Peter Henlein Nürnberg” (PHN).

As Peter Henlein, who was born between 1480 and 1485 in Nuremberg, had not yet become a master locksmith (watchmakers did not officially exist yet), the formal guild rules of the time forbid him to sign any work he did. Therefore, he apparently hid his signatures.

And this leads us to one of the most important points of the findings: the inner case had been fire-silvered. Underneath the layer of silver, the researchers found microscopic “PH” signatures, which could not be recognized with the naked eye. However, they almost form a background pattern on all components of the watch

The research examinations of the individual elements have led the researchers to believe this Pomander Watch was also most likely Henlein’s personal watch.

It should be noted that there are still many who find the results inconclusive and continue to debate as to the creator of the Pomander Watch (Bisamapfeluhr).
