17”’ | Key Wind | Cylinder | Small Seconds |

Remarks:

• There are also movements by Pierre Petignat, e.g. the 320 / model No. 1, but Jacques Petignat is not the son (fils) of Pierre Petignat, but of another Jacques Petignat! Pierre and Jacques Petignat fils were therefore probably brothers. The movements also suggest a family connection due to their great similarity.
