At the turn of the 18th and 19th centuries, in Central Europe, a few watches were produced with movements made entirely of bone (with the exception of a few elements made of brass).
Of this production, one watch is known bearing a signature, that of Joh. Zeidler in Kraslice (German: Graslitz), a town in the Sokolov district, in the Karlovy Vary region of the Czech Republic:
· Antiquorum, Geneva, auction, April 18, 1998, lot 332.
Among the other rare examples that have survived, a few watches, unsigned, are listed:
· Antiquorum, Hong Kong, auction, 4 June 1996, lot 414.
· Antiquorum, Geneva, auction, 21 April 1996, lot 346.
The latter was certainly made as a gift for Empress Josephine, Napoleon’s wife, the cock (balance-bridge) being pierced and engraved with her coat-of-arms. The Zeidler watch has a cock with the arms of the Romanovs, the Russian imperial family.
All three watches have very similar gold cases and suggest that they were produced in the same region.
The watch we are proposing today has a movement of the same kind, with a cock in a “Louis XV” spirit. On the other hand, the case of this one lets us glimpse a German realisation of the end of the 19th century in a revival spirit.
In the second half of the 19th century, a few watches with movements also made entirely of bone were produced in Russia. They were the work of the Bronikoff (or Bronnikov) workshop, which also produced numerous watches in boxwood (examples are now kept in various Russian museums and in the collections of the Patek Philippe Museum in Geneva and the Das Museum der Zeitnessung Beyer in Zurich).
