5 3/4 x 7 1/2”’ | Hand Wind | Swiss Lever | No Seconds |

Remarks:

  • In the Quick Fit catalog from 1961, the GP 73 is one of the very few calibers that is not based on a movement from another manufacturer. It therefore appears to be either an in-house development by GP or an exclusive development for GP
  • Swing-out balance guard (covers the hairspring stud)
  • Setting lever spring defective
