c.69 is normally a calibre of lepine watches. In the IWC archives there are c.69 savonettes from 1897 with the description 159901-160200 Sav.c.69, 18 Lig. Mod. 1894. I am not sure, whether anybody has seen one of these savonettes.
All other c.69 watches are lepines.
The watch I show is built in 1903, movemment Nr. 289627, in the archive that should be a lepine, but as you can see it is a (half)savonette, probablay withw a hidden second-hand. It is a Peerless case, the movement has 16 Lig.
I have discussed that watch with Ralph E., he is sure that it is unique c.69. I wonder what the forum means?!
