Hello,

I've made a silly mistake!

I was taking apart a watch I've not worked on before, and rushed it.

On removing the date wheel, the little brass coloured gear wheel on the right of the picture fell out, and I've no idea where from?

It has a raised square edged centre on one side with a hole through and a smaller raised cone centre the other. This side also has a small pin set at approx 1/2 the diameter of the wheel. It has a course tooth edge which I cant seem to match up with anything
Can anyone advise?

Thank you
Matt.

Thank you, most useful.
Mine appears to be missing the pin on which this gear sits !
Not sure how I'll fit another, it's so small. May have to replace the movement from a donor.
Thanks for your help (y)
