Use a screwdriver instead of a pointy tweezer to depress the setting lever as this will prevent you pushing it too far. Pushing too far can cause the yoke to slip over the clutch wheel and then you need to do some dismantling to resolve that.

Yup, a 1.20mm screwdriver will ensure you don't push the button too far down.

I changed a canon pinion and a winding pinion on a 2804, and I only removed the barrel bridge. After removing the stem and the pinion I had trouble putting them back. So the next time I did that I pulled the stem out from position 2. This way, when putting all back, the winding pinion just stayed on the yoke instead of me having to push the yoke back for the winding pinion to find it's place (I hope you know what I mean).

 

 

p.s. @Mark, any more videos on the way? It's been more than a month since the last one. Personally I check your youtube channel at least twice a day.

Thanks everyone all done now

Mark has been snowed under with work of late, hence no recent video uploads.

Putting the watch into hand setting position helps to get it back in without getting everything jumping out of alignment.

I believe there is actually eta tech doc recommending this.

Thanks for this. It helped me (after making that exact mistake several times).

I know that many people have had this happen to them, but strangely, even very strangely, I never have. I always get a lot of weird things that nobody else gets. Anyway, I always use the tip of brass tweezers to remove the stem. I pull the crown out and while I keep pulling the crown, I gradually press the button harder and harder until the stem releases. Maybe the next time I'll get in trouble, so knock on wood. I got used to using tweezers as I couldn't get it to work with a screwdriver the first time I serviced an ETA 28XX movement.

I haven't had the problem either but I've been amazed just how hard I had to push.

I would say it does depend on how the keyless works are set up, i have had it happen once before. Pulling the stem  to time set mode can also be a problem, that puts the yoke or setting lever under tension from it's spring and without the extra stability once the stem has been withdrawn and the set screw being loosened the yoke can flick over it's spring or something else.

I find that happens from time to time usually its something cheap Rich, and force myself to stop pushing, I've broken a set lever more than once doing this. Dials tight up to the set lever cause this , cheap Smiths are renowned for it. Too much depth in the stem slot as well,I've shortened quite a few yoke bends to make the last job of entering the stem easier at the casing up stage.

I always pull the stem out either one or two clicks. In doing this the clutch has a little more stability engaged against the date setting wheel and is less likely to flip. It's a design fault ETA should have sorted out by now. The ETA 2892-2 doesn't have this problem!

Also when the stem is out don't give the movement any hard jolts, as this sure to flip the clutch and then the yoke comes out of the notch of the clutch. You can sort it out by removing the barrel bridge and reseating the clutch and yoke, rather than removing the dial and hands, etc.
