What is this wheel for?

[Lc130]

This is an AS 2066 and I'm a beginner.  What is the purpose of this wheel?   Not seen this before.

 

Thank you

It's the equivalent of the canon pinion, that's where it slips when you set the time. Needs to be disassembled and cleaned and greased when servicing.

How do I disassemble it?

The C clip looking thing just prys off.

But inside a plastic bag or you’ll likely never see it again if you’re not used to doing it! Or a big blob of rodico at least...

Good advice.  Though,  as a beginner, I decided not to risk it and cleaned it assembled.

Well that didn't work out.  I did need a clean.  I removed it in the plastic bag but still lost it.  Amazing.  The part sheet calls it a "great wheel, assembled".   Is "clutch wheel" here the same http://cgi.julesborel.com/cgi-bin/matcgi2?ref=AS_2066

How do you get that clip back on?  How do hold the wheel steady?

Thanks

If you look at the PDF provided above and I snipped out the image the parts you need as a number. That if you go to the website they indicated you just find the number which I did and that's the part you need. Then you can click on the part and get the link that I have below at least there's more than one watch using it which increases your likelihood of possibly finding it.

Then a note regarding the numbers you find on the link below This number is the bestfit number  203/145 That's unique for the part. Then we get the description  CENTER WHEEL, OFFSET. Then this part number itself is not unique in other words the 200/1 unless you add in the watch caliber number. That's because you could find a 200/1 for another caliber and it be entirely the wrong part.
