19”’ | Hand Wind | Swiss Lever | Small Seconds |

Remarks:

• Savonnette = hunter movement
• Hahn registered another very similar model no. 63 in 1905
• The specific form of the setting lever spring of this movement was registered by Hahn only in 1921. So the movement shown here seem to be a late variant of model no. 63
