Hello everyone, I have a bit of beginers question that'd a appreciate a bit of help with. I just picked up an old Longine from early 20th C and would love to get it running. As it was missing a stem I sourced one on ebay and was hoping to give it a wind just to see where I'm at but am having problems inserting the stem. I turned both screws below the level of the stem in the photo but neither allowed me to incert the stem further. Am i missing something, ie. should i try another screw or might there be another reason why i can't get it in.

Apologies in advance if this is an obvious one, I am very new to watch repair and tinkering.

Thanks in advance

Jean

   the stem may be rusted on the crown gear inside.

Iam sorry but most responses seem to be about removing the stem but correct me if iam wrong OP said it was missing a stem and he got a new one from eBay. The stem in the picture I will assume is the new one he is trying to put in. The screw HSL mentioned is the correct screw but if after a couple turns you can’t insert and/or it won’t stay in after screwing that screw back in then I will assume the keyless works are locked and to unlock them you will need to take the dial off.

Many thanks for all the help and apologies for the delay in responding. I managed to get the appropriate sized screwdriver and did as vinn3 suggested to great effect. This allowed me to slide in the stem and lock it. I was now able to move the hands. However...

when i try to wind  the stem it immediately springs back the exact amount i have wound.

Also the lower screw in the photo [with the arrow around it] has come loose, I presume i over did it when i opened it previously and have now dislodged the connecting part.

If anyone has any suggestions I'd love your feedback, as a novice i do not wish to damage this watch so if you think it best to begin on a lesser models and leave this to the pros i would happily hear this too.

If the mainspring unwinds back through the stem then the click may have failed. On these earlier longines the click spring is concealed under the barrel bridge. 
 

Loose screw - most likely you loosened the bolt screw to far and it has fallen out. Remedy - remove dial to reveal bolt (aka setting lever and hold static while you reinsert the stew again).

      Unfortunately I'm not that lucky. I started on the train side and after I noticed the binding I pulled everything out except the driving wheel to rule everything else out. It still binds. I'm going to double check that the pinion is fully seated on the staff first, then if no joy I'll push the bridge jewel up a fraction of a mm. Fingers crossed!

      Thank you for the advise!! It worked. The setting screw was a lock/unlock to remove the rotor.

      I have that French tech sheet too, it is a little different than the English one (eg, it doesn't have the auto works diagram). BTW, it looks like you are looking up the case number in the 1979 ABC supplement. The 1974 ABC catalog does have the 3093 case. As you determined it takes the 1222-5 crystal.  When I serviced my President 'A' (which also takes that crystal), I was able to fit a 29.8 crystal from my DPA crystal assortment. Those are, in my opinion, a great deal. The assortment comes with 10 sizes each from 27.8mm to 32.4mm in 0.2 increments. I pretty much use them for any non-armored crystal that takes a high dome crystal. I think they no longer make them but Cousins has still has some in stock but when I bought them they were around $40 for the set and now they are around $100. Still, at 40 cents a crystal it's still a good deal. For the large driving wheel, I remember I once assembled the keyless/motion works first and when I placed the large driving wheel it was interfering with the setting wheel on the dial side as the teeth were not fully meshing and it wouldn't fully seat. If that isn't the issue I got nothing and am looking forward to see how you solve it 🙂

      Not sure, but just looking at it, it seems like the screw on the right may be a fake? The one on the left may not be a screw in the regular sense at all, rather a 2 position device, I think you need to point the slot towards either of the 2 dots and one will secure and one will open. Like I said this is just my best guess looking at the pictures.
