Hello everyone.

I need to 're-assemble the date wheel works on a 2836-2 ETA, and also a day and date wheel on a 2824-2.

Can anyone reference a video or instructional link.

Thanks in advance.

The calendar gear is slightly different on the 2836-2, and 2834-2 to that of the 2824-2 movement, the 2836-2 has a small flat hook spring which needs to be carefully locked into place on the underside of the calendar gear, and ensuring its the right way too otherwise the midnight date change will not function correctly.
