Hello 

I can imagine that I have to tilt the movement including inner stem into the case, after pushing the outer stem and crown into case. But I can´t "hook" the inner stem to the outer stem, even if they seem to be in corect lengths.

Kind regards

Sorry, it's difficult to understand you. What exactly you can't manage to do, and why? Please refer to stem sections as inner and outer.

Hi Jdm

I have now reformulated my first post. Let me know if it makes sense. Thank You.

I understand. The two parts are supposed to hook by pushing firmly when aligned. You could try this with the mov't out of the case.

However, I had the same problem, it seemed to me that the force needed was excessive, and I didn't want to risk breaking anything. So what I did was to remove the crown, join the stem and insert mov't in case.  Then applied locking agent and screw in the crown. It could not be really tightened it, but in my case it's a watch which not being used.

Do You mean, that I should put inner and outer stem in level and push horizontally? Because It doesnt get in level if I try to tilt as in shape of a roller coaster movement.

With the movement out of the case I would first check that the stem pieces do actually clip together correctly.

This might be easier by removing the female part of the stem from the movement and holding it in a vice whilst you then apply the male part of the stem with crown. Do they clip together as expected?

Yes? Now put the female part of the stem back in the movement; check it is properly  engaged / secured before proceeding.

Now place the movement in the case. Look along the case tube ... is the stem nice and central? Put the case flat on your workbench and try engaging the male part of the stem with crown. You must push evenly along the axis of the stem; do not push at an angle. What happens?

Hello Watchmaker

It worked! I really appreciate your time in describing it step by step as easy as possible.

      Gamblin Gamsol for cleaning?

      By joelcarvajal · Posted

      Thank you all for the replies!  Very informative! True enough, the Gamsol took some time to evaporate and does leave a residue. So not all naphtha are created equal!  Need to find alternatives then. i was able to try Hexane recommended by Alex and it seems great.  I wonder what the cons are?

      Yeah, I saw that in the tech sheet but I don't see how it can be adequately cleaned with the friction pinion still in place. I've accidentally pulled the arbor right out of the wheel once when I used a presto tool to try and remove it. Mark shows how he does it with the Platax tool. Those are a little too pricey for me so I got one of these from Aliexpress and I just push down on the arbor with the end of my brass tweezers. That usually gets it most of the way out and then I just grab the wheel with one hand the and the friction pinion with the other and gently rotate them until it pops off. Probably not the best way but it's seemed to work for me so far.

      Movement inserted from crytal side

      By Zedster · Posted

      Thanks, Jon Sounds like a plan. Obviously I'll have the face on so do you think gripping with the holder will create any problems, but I will check in the morning to see how feasible it is but I assume it only needs to be lightly held. As for holding the movement instead of the holder won't be possible in this scenario as one hand will be puling on the stem while the other pushes the spring down. That was my initial concern is how the hell can I do this with only one pair of hands. All the other times I've had to remove the stem hasn't been a problem, apart from the force required to release the stem from the setting lever, but now I need to fit the face and hands its sent me into panic mode. If it had the screw type release things would be a lot simpler but that's life 😀   Another thing I will need to consider is once the dial and hands are fitted and the movement is sitting in the case I will need to turn it over to put the case screws in. I saw a vid on Wristwatch revival where he lightly fitted the crystal and bezel so he could turn it over, is this the only option or is there another method?

      Main spring

      By nevenbekriev · Posted

      Hi Jon, do You think that relation spring torque - amplitude is linear? I would rather guess that the amplitude should be proportional to the square of the torque. I had once idea to check it, but still haven't.

      I did not. I thought about it, but I had cleaned it in my ultrasonic, and the tech sheet shows lubricating it in place already assembled, so I figured discretion was the better part of valor. Although since I have to depth the jewels anyway, maybe I pull the pinion off to rule it out 100% as part of the problem. Do you know if there's a safe way to do it? I don't want to use a puller because it would push down on the plane of the wheel, and that seems like a Bad Idea. I thought about using a roller table remover, but I don't think I have a hole stake pointy enough to push it down.
