Bulova 11AC extra part help needed

[lxt123]

After taking out the movement from the cleaning basket I found an extra part. I've tried to find the tech sheet for this movement but I had no luck.

I guess it was stuck under some other part and got loose in the cleaning process.

Any help id-ing it, is very much appreciated.

As you can see 1.75mm OD and o.73 ID

Thank you,

George

That looks like the inner ring of the crown wheel.

Must be the crown wheel ring. Try to see if it would fit in here.

The inner ring it was.

Thank you.

Always important to learn from your mistakes like always look for the inner ring before dismissing. Always remember to tighten the dial screws they don't have to be supertight but they have a habit of coming out when you're cleaning the watch depending upon how you doing it. So I think both of these for one of the first things I learned when cleaning watches. Which of course is why we all knew what the ring was instantaneously.

Yeah. And always check your cleaning jars and baskets carefully for small parts hiding somewhere after every use.
