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

Remarks:

• The movement is also marked with a logo (PP with star). The PP matches Pierre Petignat.
• Pierre Petignat registered another work in 1896 under the number 3467, again as model No. 1.
• There are also movements by Jacques Petignat fils, e. g the 506 model No. 3. However, 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.
