Removing movement from the case?

Can anyone give me any pointers on removing this movement from the case? I thought it was a breakaway stem but I don't think it is now?

I'm confused.. in the piciture I see the mov.t removed from case, and the case upside down with the dial reversed inside.

I have come back to this watch as I need a project for the weekend. Anyone have any ideas on how to remove this movement form the case? I have flipped the movement ove and removed the dial but long term I need to get it out and back in!

any direction or suggestions would be very much appreciated!

 

thank you in advance!

That is a strange one? Two piece stem? Looks like the setting lever has a screw? So it can't be lift to remove ? Maybe the movement is only a tight fit in the holder? What does it say on the movement? Any numbers or name?

Looks like a normal straight forward removal to me.  This lever is held with the screw I have circled which can be loosened from the movement side which allows you to remove the stem. A bit confused with the pics

Gary has already stated that the movement is still in situ in the case back, therefore there is no access to the stem release screw.

The photo is not particularly clear but from what I can see it has to be a split stem. The stem is held in the movement by the set lever which appears to be a standard design as CB has suggested. It would be impossible to tighten the set lever screw with the movement in the case back, therefore the inner part of the stem must be in place before the the movement is installed and the outer part of the stem has to be installed after installation.

I would be inclined to dismantle the keyless works as far as possible to clear the decks and see if it is possible to get a clearer view of the stem where it goes through the case.

Hi E veryone,

I will try to take better photos this evening. Marc is correct. the movement is flipped in the case still in there. The dial was loose and I was able to remove it so we are seeing it in the case just flipped. I tried pulling the stem as I have a Wittnauer that has a split stem but it didn't give. I will try it again or take photos and post. 

Thank you for assisting me with this one. I need to work on it this weekend! Will post more photos tonight.

Tried to take better photos and tried pulling hard in case it was a break away. No luck 

 

! Seems I will have to resize my images. Bear with me!

I don't understand why you can not access the other side. Some watches the crystal is set in it's own ring which also opens like a snap on case back. I presume this how you have got this far. The back will also open either via a snap back or screw action.

Front like this

Gary, the case construction is the same  as a Roamer watch that I service a couple of years ago.  It will be a split stem that has to be separated to remove the movement.  These can be very stiff to separate with a straight pull and leverage may be required.  This was the case with the Roamer.

You might be able to turn the stem to a position that will allow the stem parts to slide apart as you to gently prise the movement out.

two piece (split) defiantly requires leverage.  I use tweezers under the crown for the slight more leverage,  if the 2 pieces are rusted together - use penetrating oil and heat.  a well worn 2 piece stem comes apart too  easly.   vin

    • As far as I know, the only time an epilame treatment has potential drawbacks is when something is rubbing on the treated part w/o lubrication in between creating abrasive dust. That is, I don't believe in the method of "running the watch to make a groove through it first in the pallet stones where the lubrication is then placed". So, I think the rule would be; do not epilame treat parts where rubbing is going on without lubrication. Other than that I don't think we have anything to worry about. That said, I'm not an expert, and I'm always happy to learn more. Has any other repairer than Alex suggested or explained the "making-a-groove" method? My impression is that it's just something he constructed in his mind. I have not perceived it as a generally practiced method. Again, I could be wrong!
    • Post some pictures , some good close ones of the parts you've described. 
    • Ive never used epilame H only information i have read and mentally stored about it mostly from Nicklesilver here and elsewhere ( the fork horns thing ), maybe the residue powder that is removed has some grinding effect ? So probably a good idea to limit its application areas to only the absolute necessary. Yes as far as i know epilame rubs off relatively easy, the technique of running the watch to make a groove through it first in the pallet stones where the lubrication is then placed. This i understand creates the barrier for the lube to sit up to. If i can find a good balance of pros and cons of its use then thats one process i can avoid by using a thixotropic lube on the stones. The epilame i would say allows for a more fluid lubrication to be used that would increase amplitude on low beat movements. The stearic acid powder is extremely cheap, the problem is the fuming process to coat parts, is not selective , the whole part has to treated in this method. If epilame residue can cause wear then thats not good, if I remember the conclusion was not proved entirely just a general assumption between watchmakers. The thread is out there somewhere, the same discussion is also old on a facebook group.

    • Following on from my question about identifying screws in the AS2063 movement that basically fell out of the case in bits, I’m pleased to report that I’ve got it all back together, and the movement is running pretty well.    But… There’s something wrong with the keyless works and hand setting. It’s fine in winding and quickset date position - these work - but in hand setting position winding the crown turns the whole gear train.  I don’t really understand how it’s meant to work. It doesn’t have a traditional friction fit cannon pinion.  The second wheel is unusual with a pair of smaller pinions on it, which seem to interact with the barrel and the motion works.    Could this be the problem? I must admit I just cleaned it and popped it in place when reassembling the gear train. I’ve lubricated the pivots but didn’t do anything to the extra bits on the second wheel.    Does this make sense and is anyone able to figure out what I’m doing wrong? Thanks in advance, as always.    ETA - the parts list calls it the Great Wheel, not second wheel. 
    • You're thinking metal to jewel in general I guess. Maybe it would be a good idea to peg the pallet staff jewel hole on the main plate after the epilame treatment. I think that could work as it is my impression that the epilame doesn't sit very hard, but I could be wrong about that so feel free to educate me. I didn't remember that 9501 was thixotropic (thanks for the link). That would mean it's even runnier during impact (lower viscosity) so perhaps it's time I get some fresh grease as mine seems a bit too runny. What I have seen is a whitish surface after washing but it goes away if I scrub the surface with a brush in a degreaser (Horosolv). I don't think it embeds itself in the metal but sticks very hard to the metal. I don't worry too much about the cleaning solution. I just want perfectly clean parts and my solution can be replaced for little money (ELMA RED 1:9). Anyway, I quite often need "to strip back and rebuild" and scrubbing parts by hand isn't exactly the most stimulating part of a service. Just got confirmation that Moebius 9501 has a lower viscosity (68 cSt at 20° C) than 9504 (305 cSt at 20°). The viscosity of Molykote DX is 285-315 cSt at -25° to +125° C. I was surprised to see that the viscosity of Moebius 9010 (thin oil!) is higher (150 cSt at 20°) than my 9501 grease!
