Hello all.
I recently picked up this Flieger 3706 chronograph and had a question regarding regulating.
All is well with the movement--the amplitude is good and the movement is in beat, but it loses about 18 seconds per day.
Looking at the Triovos regulator I'm used to the friction versions where gross timing is done with the index and fine regulation is done with the screw but on the IWC version the index has gear teeth that mesh with the screw so moving the index isn't possible.
Can I bring the watch into better time keeping with the screw alone? About how many turns would I need to make with the screw to make it gain 20 seconds?
Any advice would be greatly appreciated.
