Recently picked this guy up, and took it apart for cleaning tonight. Looks super clean inside as far as wear and tear goes, but there are puddles of oil everywhere! Hopefully a good cleaning will bring the amplitude back up. I did learn that the automatic bridge is spring loaded, which you can see below in the yard sale of wheels and gears all over the place. Sorry in advance for all the pictures and if some aren't in perfect focus. I take a lot of progress pictures through my microscope, and I figure if someone is here looking for help, they might be useful to them. And this is where I stopped, since I got into the wine.

I recently bought this but not on ebay. I figured if I want something Japanese I better check Japanese auction sites since these don't seem to pop up on ebay. I paid 83 € plus shipping & taxes. I think it was pretty reasonable for a complete set in good condition.

The 11AN/11AO family is probably my most worked on movement (working on one right now). I've had the auto bridge spring into the ether myself. Bulova tells how to wind down the mainspring in their tech sheet but I've never had success following their instructions. There are definitely some quirks with the movement: oiling the upper sweep second wheel pivot and the dial side pivot of one of the auto works wheels which is inconveniently placed between the spokes of the escape wheel. the Date Corrector Setting Wheel has to be placed in the exactly correct orientation or the quickset date change will not work. the setting wheel that interacts with the sliding clutch goes chamfer up. I've made my own 'tech sheet' for it and shared it in case it's of use to anyone. Bulova 11AOACB.pdf
