Cal 354 escape wheel help

Hi, I'm struggling well reassembly after a service. The top post of the escape wheel is now to low and not seated in the jewel. I can't tell if the escape wheel was damaged disassembling or if another issue.

The bottom post is in the holed jewel, hopefully supposed to be a holed? And possible going to far down now?

All the other gears line up in the bridge.

The escape wheel doesn't appear damaged. Both ends are straight and it's an S/S part. I don't think an end just sheared off looking at it.

Any help with the jewel position would be helpful before I spend 75 on a new wheel.

Sounds like I need to invest in a microscope.

Would/could an ultrasonic cleaning cause a jewel to move?

I'll report back with pics

Unlikely - most probable that the pivot has been snapped off.

They were always a pain. Others fine. Escape was always a little tougher to get it.

Take the bridge off and check the pivots

A broke escape wheel pivot would be extremely difficult (if not impossible) to see with the naked eye, or even low magnification. With a 15x-20x loupe it is obvious.

If you don’t have those and want to check right now, a very tight zoom on an iPad or high quality smartphone camera might get you there. For even more zoom, you can press a loupe up against the camera. This a pallet fork I photographer from my 2020 IPad mini 6 with a 20x loupe against the camera lens;



And here’s one taken with only the iPad camera at full zoom;



FWIW, I’d put my money on a broken pivot. I also recommend taking a look in the pivot hole on the bridge/main plate to make sure it’s not stuck in there. You shouldn’t need much magnification to see that if you hold them up to a light.
