Oris 292EW

 Well this one sure was a pain. I didn't realize what I was getting into.

This Swiss made Oris movement has a pin escapement, no pallet stones - weird.

The 3rd wheel oddly has two pinions. The lower one is not used. It engages nothing.

The parts are all quite crudely made too. The plates appear to be alluminum.

Solid balance wheel, no timing screws.

There are a couple of divots made to true it at the factory.

This was a pain. The lever has it's own bridge. That's fine except that the train bridge, the part that says "Oris" in this image, extends under that lever bridge so that the screw hold both. The train bridge is warped. It doesn't sit flat without being secured. So I had to install the pallet and its bridge while holding the train bridge and keeping the train pivots in place.

Here is the extra exposed wheel and the shaft that carries the sweep seconds hand. This design is typical. The shaft passes through the center wheel shaft which is a hollow tube. The extra wheel goes on the 4th wheel, where the second hand would be on an watch without a sweep second hand.

The shaft inserts from the back and is held in by a flimsy piece of bent brass. The top of the 4th wheel pivot is sticking up. The extra wheel goes there.

The setting mechanism was pretty difficult to assemble. The setting spring, at the left in the image, is actually on the other side of the plate, between two riveted pieces.

This part is pictured upside down. It goes on the movement flipped over so the round parts hold the gears. The task was to somehow move the spring up to it will press on the pin on the left of this part, line up all the gears on this part, and get the screw in. Oh, and this part also holds the minute wheel, not shown, so that's floating around while assembly is attempted as well.

The stem barely works, nice dial and hands though.
