ETA Movement Replacements

[Tim]

I bought a brand new DJ from one of our dealers. The movement has problems and I would probably need to get it serviced for it to work right. The DJ from our dealers are listed as having a 2836-2 ETA Day Date movement. I suppose they are doing the day date model movement because it is more efficient to work with a fewer number of movements.

I was thinking however that I have a bunch of junk watches with 2824-2 ETA Date movements in them. I bought the watches because they were only $30 and I was hoping to use them to get movements that I can practice with since while I am learning anything I touch I will obviously destroy.

My question is are these 2824-2 movements a drop in replacement for the 2836-2. Will the date wheel from my 2836 fit on the 2824 and will it be in the same position?

Thanks for the info.

Maybe I'm wrong, but datewheel position is the same in both movements.

The 2824 and 2836 are different heights so the stem/crown is in a different place.

Yes, by .25mm, doesn't sound much but could cause problems esp. with a screw down crown.

Though it's not a whole lot thicker than the 2824, he 2836 has the stem position further from the dial, which as posted earlier could cause alignment issues. For example, in a genuine DJ case, the 2836 won't work because the stem won't line up (too far from the dial), but thte 2824 fits perfectly.

This is correct, in fact the datewheels are interchangeable. However, the 2836 datewheel is a little different in that it has a lip and is a bit thicker. You'd have to see them side by side to understand. Adding a 2836 datewheel to a 2824 will create some thickness.

Tim,

Have a search on the ETA tech page...each movement has a cross reference for interchangeability of parts.
