deniz21 Posted January 1, 2010 Report Share Posted January 1, 2010 hi guys, i did today a litle bit of greasing the rotor of my swiss eta movement. cause the rotor was very noise and loud and also how can i say this clapping when in motion or what ever then i found in the garage a wax that i think fit for this, so i openend the caseback, and the magnetic cover, and with a toothstick i gave the rotor bearing a little bit of lube:) and what should i say the noise is gone but i have alittle question now, bevore i did this i was hearing the rotor was spinning but now..nothing, i also was trying first to tighten therotor screw but noting it was tight. but now to the question is it correct when you turn the wach 360 and look at the rotor that it flows with your motion, what i want to say the rotor is not to tight now right? i mean he flows with my motion when i slowly turn the watch from one side to another, this is correct, i hope i damaged nothing Quote Link to comment Share on other sites More sharing options...
TeeJay Posted January 1, 2010 Report Share Posted January 1, 2010 It sounds like you've done it just right Quote Link to comment Share on other sites More sharing options...
krpster Posted January 1, 2010 Report Share Posted January 1, 2010 I don't think you can prevent the rotor from spinning by over tightening the screw. Worst case you may damage the screw or the thread receiving it. However, if you really put some force while tightening the screw I suppose it may be possible to damage the auto winding module. Chances are good that you are OK. My only curiosity is that you lubed an ETA rotor? Typically this is unnecessary as the real deal has what it needs. There should be some noise coming from your rotor esp if 7750 as they are notorious for their sound. Cheers Quote Link to comment Share on other sites More sharing options...
deniz21 Posted January 1, 2010 Author Report Share Posted January 1, 2010 ok thanks guys puuuh i hope so teejay yes it was a eta rotor, i looked at pics of this movement it was exactly the same, with the engraving on it and stuff.. but krpster, yes but mine was loud imho, when i slowly touchd the rotor and moved it a little bit he was swinging back and forward after the little touch and there he makes some noises, like clapping to metal things togethere, but after the lume in the bearing the noise was gone, when i rotatet it slowly there was no big noise but when it was swinging there was the noise.. maybe normal? i dont know. but its history i only think the bracelett is clapping know when i shake the watch, but this i maybe do later, need a dry wax for this.

mikellem Posted January 1, 2010 Report Share Posted January 1, 2010 Good guestion? What is the answer? MM Quote Link to comment Share on other sites More sharing options...
deniz21 Posted January 1, 2010 Author Report Share Posted January 1, 2010 and i looked again no i think the autowinding is ok cause, when i turn the watch and the rotor moves, the two little gearwheels start to move. all ok the right, i was little bit afraid cause the watch is the first one i ever opend i did something on it i also screwd the regulator screw a little bit cause it runs 10-15 sec a day to fast. hope i didnt turnd do much on the screw. but tomorrow i will know that but its a great feelin to do something on your own much never did bevore Quote Link to comment Share on other sites More sharing options...
r@f Posted January 21, 2010 Report Share Posted January 21, 2010 What grease or oil is the best to use to lube the rotor ? Regards raffo Quote Link to comment Share on other sites More sharing options...
theflyingdutchman Posted January 21, 2010 Report Share Posted January 21, 2010 and with a toothstick i gave the rotor bearing a little bit of lube:) and what should i say the noise is gone Do you or anybody have a pic of where the lube/grease/oil has to be exactly placed? Thanks! Quote Link to comment Share on other sites More sharing options...
Bike Mike Posted January 21, 2010 Report Share Posted January 21, 2010 What grease or oil is the best to use to lube the rotor ? Regards raffo A very fine oil is to be used on the rotor bearing. A very small amount. Over oiling will cause the oild to spread elsewhere into the movement. This is very easily done if you have never serviced a movement before. A small drop (and I mean the tiny amount on the tip of a fine dip oiler) should be placed on the bearing balls. As the rotor moves the oil will be distributed through out.

r@f Posted January 21, 2010 Report Share Posted January 21, 2010 e tiny drop of wd-40 ? Quote Link to comment Share on other sites More sharing options...
lufcmattylad Posted January 22, 2010 Report Share Posted January 22, 2010 if the rotor spins (over excessively in my case) and the movement is not charging correctly i.e the watch stops regually during normal wear, but does charge a tiny amount with an over excessive shake of the watch... is this a rotor screw issue or a movement issue? additionaly, what type of screwdriver do i need for rotor screws?
