Eberhard & Co. launched in the 1990s as part of their "Edition Antiquité" the reference number 34000, this is the Edition Antiquité No.. 9. This special timepiece features a Zenith caliber 146H ratchet wheel based on the Martel 749 or Zenith 146M caliber. At that time, Eberhard & Co. acquired a remainder of old original Martel column wheeled movements that were limited to 850 units in a limited edition, namely the Ébauche Les Ponts-de-Martels. The installation of particularly outstanding works has been a tradition since the company was founded. Even Georg Eberhard had collected rarities and built technically unusual and particularly outstanding works in Eberhard chronographs.
