2836-2 Stem Release Button


Recommended Posts

Hi

While casing the movement and sizing the stem on my 2836-2 I pushed too hard on the stem release button and now the stem doesn't lock in place.

So, does this mean I have to take the watch apart again to fix it?

Maybe just the keyless works? Is there a magic word I can say? How about a potion.

Sigh...

i think we have been there before.  no offense meant.  in my exsperience with the push pin or the screw;  if you mess up its "dial off"  at least.   the experts usually don't have this probem.  vin  p.s.  if the dial pin retaining set screws are "rusted it",  - another story.

Not all movements require you to fix this from the dial side but I don't know this movement so you'll have to trust the others... It's sad when this happens, and frustrating, but we've all been there I think...

You may be able to get it back together by removing the auto-winding stuff followed by the barrel bridge. The set lever will be behind the sliding pinion but I think its doable.

Having the stem in the hand-setting position should make it easier when re-moving and installing.

Hi all

Thank you for all the input - BIG HELP...

I was able to repair the problem by removing the dial and day/date dials. The setting lever was completely out of place so I removed and re-lubed everything before reassembly. It works well now.

However, I am having a problem setting the hands because I have been sizing the stem and the crown is quite loose making it impossible to turn the hands forward until the date changes. I am still sizing the stem for the screw-down crown so I don't want to put lock-tite on the stem until it is sized.

Should I size the stem until the screw-down crown fits and then put lock-tite on the stem so I can find midnight by turning the hands until the date changes?

This is probably a kind of stupid question.

Who knew casing a watch could be so difficult?

Hi all, again

Any tips on sizing a stem for a screw-down crown would be welcome. I've never 'done' one before.

Someone suggested that the end of the stem should be basically even with the outside of the screw-down tube and that seems to be where this stem will end up. I've been very careful nipping bits off. The old "cut it off twice and it's still too short" saying comes to mind...

Hi J

I have a calliper and I've used it.

Yes, I watched that one as well as one Mark has on line. My issue is more the spring-loaded crown. Do you measure to the point where the crown is screwed down? I'd imagine you do since this is where the winding has to start.

I was also concerned as to how much pressure the spring in the crown is putting on the stem inside the movement.

Anyway, I'll try the sharpie trick - it's a good one for marking how much to take off. 

Thank you

Place the uncut stem on the crown and insert into movement. Push the stem/crown into the winding position and press the crown in so that it reaches its limit and then measure the distance from bottom of the crown to the case. Add 0.1mm to be safe.

Thank you, J. I think I've got it. Putting the hands on is my bug bear now. It didn't have a wavy washer supplied so I stole one from another watch. I think it needs a spacer for the day/date stuff to work properly.

The watch works quite well. I'm almost there but I'm taking a break because my patience is wearing a bit thin.

I had 2 Innis and Gunn IPA's instead. 

I am having a problem with the second hand. It has a long 'tube' on it and it is just too high and rubs on the crystal stopping the watch when the case is tightened. It doesn't seem to want to get pushed on any further.

Should I try to push it on further - I don't like this idea - or should I try to shorten the tube that goes over the second hand arbour? I have no idea how without crushing it. Everything is working except for this.

Maybe they sent the wrong second hand - wrong case or maybe it's the watchmaker...

The case and hands are all new. I am casing a 2836-2 movement I'd been working on earlier for training purposes.

The hour and minute hands are fine but the seconds hand just seems to have a very long tube on it. I don't think I'll need to file much off before it will fit. 

I don't have a jeweller's file. I'm wondering if fine emery paper would work better.

Thanks Neil

I took some off but I need to take more off. The 'bush' is very long on this thing and unfortunately the only way to see if I've taken enough off is to put it together and try it, etc.

Keeps me busy.

If you have an easy way of reattaching a hairspring stud to the balance cock of a Bulova 6CF I'd love to hear it.

There's lots to learn...

I wrote a detailed posts about fitting crows both standard and screw down, and for some strange reason they have been deleted.  They were pinned to allow easy acces to them.  If you read this Mark, could you please reinstate them please?

    • people be honest.... Swatch is evil for the watchmakers and repairers, BUT not everything in watches from Switzerland is from the Swatch-Group. As far as i know, Selitta got sacked by Swatch as a Movement-Assembler for them and they started to produce Movements in their own Name with slight Modifications. As far as i know, they sell Parts to the Market for their Movements. In most cases, if a ETA-Movement fails, it is a valid Option to replace it with a Selitta Movement, which i consider the Solution for this Mess with the Swatch-Group...... I have no Connection to anybody at Selitta, but being a Swiss-Guy, i still like to have Swiss-Made Watches, but not from the Swatch-Group.   ok ? regards, Ernst
    • Just one more greedy act by Swatch. They started a number of years ago here in the US..cutting off supplies to watchmakers that could build complications that many Swatch houses couldn't even touch. Old school masters who had gone through some of the most prestigious houses in the world. Otto Frei has some statements on their page about it. I tell all my customers to avoid new Swiss watches like the plague,..unless they just want an older one in their collection that still has some parts out on the market, or they have really deep pockets and don't mind waiting months and paying through the nose to get it back. Plenty of others to choose from..IE Seiko,..or other non-swiss brands Even a number of Chinese brands are catching up with the Swiss,..and I think that in time, their actions will be their downfall
    • Yes. If that's not what you are experiencing...start looking for something rubbing. A 1st guess is that one of the hands is rubbing against the hole in the center of the dial. Especially if you now have lower amplitude in face up/ face down positions.
    • Once a movement has the dial and hands put back and it is recased, would you expect the assembled watch to have the same amplitude as when the movement is in a movement holder and is without hands and dial? Thanks
