Need advice for this Rolex lady cal.1160

[Oyster]

Hi everyone at the forum.

I just service this lady Rolex cal.1160 and the reading is very good both dial up , dial down, after putting together ( i attached some pic. ) but then for couple hours the rate jump like crazy and the timegrapher can't even read, when it does read the rate goes crazy around +400 sec/day and the watch run 15 sec fast every minute.

Its sounds to me that the hairspring could still be dirty, you need to demagnetize the whole watch or it could be both.

The watch now stop, must be shaken to tic again, I Put the balance in the plate and in the washingwashing machine, I also clean the jewel cap and everything, but I noticed the KIF is broken, this might be the problem ?

Yes that will cause a problem. You need to fix that first.

You say you just serviced the watch and all was fine to start with. Check the hairspring for oil contamination and any coils binding together.
