Having just acquired a 1952 Patek Ref 1491 'Scroll Lugs' Calatrava with 12-120 Movement.....
I find that wearing it daily....it loses between 15-20 sec a day.
I intend to open the back and adjust the screw thread which moves the lever on the adjustment scale....
Any advice as to what tool to use to do this?
And any idea of how much to move the dial to make up this deficit?
Any help would be most appreciated?
