10 1/2”’ | Hand Wind | Swiss Lever | Indirect Sweeping Seconds |

Remarks:

• The manufacturer of the Shock-Resist shock protection, Erismann-Schinz, was not registered until 1963. The movement therefore appears to be a newer version of the Felsa 300
• The dial side is marked with the Felsa logo and 294. The 294 is the basic version of the movement with small seconds. The Felsa 300 differs from the 294 only in the sweeping seconds, hence the same plate
• The setting lever spring on the movement shown is defective
