Caravelle 11DP (citizen 0241) Stem falls out.


Recommended Posts

I serviced my first watch a Caravelle 11DP. Its running good but I am having a continuing  problem. As soon as I install the movement into the case and add the "movement ring adapter" the stem can be pulled out without pushing the release button. I removed the movement, adapter, hands and dial to see wheat the problem is.

I found the setting lever had moved inwards away from the notch in the stem which holds the stem in place.

I dissembled the key less works and re lubed and reassembled. Everything was perfect.

Until I put the movement in the case and added the adapter ring. I looked and could not find anything interfering with the setting lever.

I do have a parts watch that I could replace the setting lever and see if that helps.

Oh and the hole where the setting lever sits in the main plate is super clean as I checked that first.

Any ideas?

Just to make sure, the setting lever has two notches in the post that goes into and through the mainplate. The spring (which has an orientation) which holds the setting lever down goes into the top notch, not the lower one. It's also possible that if that spring isn't providing enough tension to keep the setting lever engaged with the stem, when you case the movement and insert the stem it might push the setting lever out of position. I don't think you need to push down on the setting lever post from the train side before inserting the stem on this movement but maybe try so if you haven't yet. Before putting in the stem, look and make a mental note of where the setting lever post that engages the stem is sitting and when you insert the stem make sure the notch in the stem is lined up with that.

Also, are you sure the stem is long enough?

Are you rotating the stem as you gently insert it to make sure the square part of the stem is lined up with the square opening in the sliding pinion?

When it is in its case are you sure the stem is pushed right home. A common cause is if the button is screwed to far onto the stem it is not right home. So try a little longer stem if you have one, or a button with a longer pipe.

The spring has a small 'V' shaped bend in it. As shown below, the bottom of the spring rests on the mainplate, so that the spring has a slight activation to push the setting lever down.

This is what I found. The pin on the left is what came out from the watch. The other is from another movement. I had the spring in upsideddown. The curious thing I noticed is the pin from the spare movement only has one slot or groove. Do you know why they are different? The dials and hands are different also.

I'm not sure why there are two different versions of the setting lever. I've worked on a handful of these and have only seen the one with the two notches. Is it working correctly now?

    • Thank you for this post. Adding on to it, I've done a little digging trying to get the most bang for my buck. So I really wanted a set that had a base. You can buy the screwdrivers for around $33 usd 10 Piece Screwdriver Set. The base is around $32 usd Rotating Screwdriver Base (Grey) plus $20 in shipping, with tax you are looking at about $90 which is an excellent deal for what you get but I still didn't want to spend that much. I saw that they had the 9 piece set w/ base for $59 usd 9 Piece Screwdriver Set W/Base and I had a 'welcome discount' and got a matching 3mm screwdriver for 99 cents. 3mm Screwdriver. (without the discount the screwdriver is $6) With free shipping my total was $66.55 usd. So, I saved about $24 to go without a slot for a 3mm screwdriver. I'll take that! I hope this helps anyone looking to save a buck or two. Also, this corrects the issue of the orange 1.8mm screwdriver. 😉
    • No hex wrench needed there. Screw driver in case of AS1475 or just push the poinst down in case of Poljot2612.
    • Well, what is written here can't be explained with the wear of the winding/sliding pinion. Probably it is some kind of delusion from You side. But it prevented the people from pointing the reason of what is happening. Otherwice, this kind of wear is one of the common problems of winding works in watch movements. It meets often in old or cheap movements, or particulary in negative stem system pocket movements where not proper adjustment of the sleeve that guides the stem is done.  
    • Well I started with the rotor, then I couldn’t find how to let down the power so I removed the balance then found the click and let down the power.  After that I took apart most of the watchmaker side with the exception of the hour wheel which was still held by the cannon pinion and the hour wheel bridge which I put back when I realized the above.  I then went to the dial side and removed the cover plate. There were a few flat part which I had no idea what they were or where they should go as they got stuck to the plate by lubrication. Luckily I found an assembly video of that movement by the watch smith and he explained that those parts are part of the quick date setting system.  So I put them back in place and took a picture before continuing the disassembly  One thing I keep hearing in video or seeing in forums is that Chinese movements are often not lubricated. WellI can tell you the one I have is drenched in oil. Everything is stuck by capillary action on the dial side and I see pools of oil under each wheel.  Quite a bit of lint stuck to the oil too Just realized there were 3 screws, 2 holding the yoke maintaining plate and 1 holding the setting lever jumper.  I hope they are the same because I mixed them up and I can’t tell them apart.    Done with the disassembly and done for the day. For the reassembly I have a video to follow which is great because the dial side is quite complicated and I couldn’t take good pictures of the components position as several got stuck on the plate by lubricants as I lifted it so I never saw where they were supposed to be. 
    • I have one, but I don’t have the hex wrench to remove the stems. Does anyone know where I could get these in USA? Thanks in advance for any advice kind people!
