  1. Thank you all, it's really nice to come back after a long while and find such a helpful welcome back!!
  2. Hello all, I'm trying to service a nice Bulova 11 BLACD movement. I accidentally (yes I'm still a beginner, it happens sigh) lost a washer, it's the one that fits over the hour wheel. Part n.86 in cousinsuk dyagram. Question: do I have to search for this specific part or is it possibile to use a third party washer since they are basically standard components? TIA Giuseppe Itlay
  3. My very first movement disassembly and servicing, despite advice given on this forum, was a 7750. I did it, incredibly everything went fine, but was definitely difficult and sometimes frustrating. I'd recommend something a little easier.
  4. via ´╗┐the fine adjuster, the one with + and - sign
  5. Definitely ETA. Actually it's an Omega version installed in a Speedmaster Reduced. Top grade with glucydur balance wheel.
  6. I'm having some unexpected behaviour from a eta 7750 that I'm trying to regulate after servicing. I went through service procedure using correct lubricants. Everything went fine. Actually I have some doubt on lubrication of incabloc wich I'm not sure I did correctly since I'm afraid that too much oil was placed in one of the two stones. The fact is that when I finished I wasn't brave enough to clean and lubricate it again ... shame on me but I felt that task to be very very difficult. Anyway after reassembling the watch I had it at my wrist for a week and it showed a great consistency at -10 sec a day. It'a stop grade movement and resting at night in DU, DD 9UP and 3UP positions always showed something between -14 -6 I was very happy with that result and I thought that a little regulation would have brought it to a very fine time keeping. Then I reopened the caseback and slightly moved etachron arm, that was resting in a nearly neutral position, in the + direction. Nothing happened (measuring with timegrapher open source app) Did it again, another slight push. Nothing ? ok I must have gone the wrong direction, then pushed all the way toward - Nothing happened. Ok this is annoying, all the way toward + nothing here I am, what I'm I missing? How come moving the regulator arm from - to + does not make any variation? I'm lost
  7. What a great place is this! Thanks everybody for your help, special thanks to watchmaker for such a crystal explication!
  8. Haven't tried yet buy I think that Is the way to go. Is Just that I Haven't seen anything likes this in any video tutorial so I'm a bit araid of Messing up things.
  9. Yes, sorry I was missing the riht term. Clasp, I mean a C shaped clasp. So it must be removed in order to dismantle the winder? it seems aplied to the stem and does not move when pushing the push down bolt.
  10. Yes it is, it'a PC (auto module + date) 17 j unadjusted. I've alredy checked Ranfft database and in that image there is the same misterious (to me at least) component!
  11. Hello I'm starting to service a vintage zenith with 2572PC movement in it. First problem is I can't seem to find a way to release the winder. This apperas to be the simplest type of relese system as a push down bolt is easily spotted. The point is it just doesn't release and this is where doubts come in... Am I missing something? In the attached image I'm trying to show what is unexpected to my unexperienced eyes. TIA Giuseppe
  12. Hello everybody, I'm in need of some advice because I don't know if a red gasket (case back gasket) should be lubricated with some silicone before fitting or if such procedure is recommended only for smoother rubber gaskets. In genearl would someone kindly explain the correct approach with lubrcating casback gaskets? Thanks! Giuseppe
  13. Thanks Joe, I was wondering if a bit of Loctite would do good but I was afraid to share this thought !! Thanks again.
  14. This is the reason why I'm asking if that sign of wear can compromise how the screw will stay in place. Despite of those signs I see enough space for the screw to make pressure to the bridge and hold it in place. And the slot on the lower bridge where the screw fits shows no sign of wear. I lack in knowledge here and I'm definitely afraid that the screw might fall apart again. To my eyes the rest of the movement is in perfect condition. Thanks for answering!
  15. Hi, in order to buy appropriate spares in my attempt to service an Omega 175.0083 (7750) I need some advice: 1. I've already been suggested to replace MS: Barrel is Ok and I'm thinking of buying a new MS and moebius 8217 for barrel lubricating as I don't want to spend money on recommended Kluber 125 grease. Should I consider instead buying a barrel complete (assuming Barrel complete (180.1) comes with MS installed) wich supposedly comes prelubricated ? 2. Attached image shows automatic device bridge with evident sign of wear from where, to my understanding, the problem orginated: a screw came off I cant find original part. ETA part is different from Omega in that the Omega is larger and partially covers hammer two function and the chronograph cam. Beside that and since the watch has no crystal back case I think those parts are perfectly interchangeable. Do I need to replace the bridge or are there alternative aproaches to this problem? TIA Giuseppe
