17 1/2”’ | Hand Wind | Swiss Lever | Small Seconds | Chronograph |

Remarks:

• Chronograph:
  • Mono-pusher
  • Column wheel actuated
  • Central chronograph seconds
  • 30 min counter at 12H
• Base movement: Valjoux 54
• The movement comes from a LIP Chronotachymètre Savonnette (hunter) pocket watch, in which the pusher in the crown does not activate the chronograph but merely opens the cover. Therefore the movement has a second push-button (at 9 o’clock on the bridge side) to activate the chronograph.
