Cheers mates..
Have just cleaned and oiled and put toghter an ETA 2872 yesterday. The movment started just fine , but after a while it started to run like h......it when like 5 min gain in one hour.
And when I tried to adjust it with the speed stud while I had in he timegrapher, I did not get any change, nor either when I tried to adjust the beat error stud.
The timegrapher just show dots all over the screen, and sometimes the timegrapher did not show the imput on the screen, but I can hear the beat sound from the watch all the time. ( have tried it with other watches, so there is no error with the timegrapher)
Where to start adressing the problems??? Help!!
