I am looking to branch out from servicing / repair of mechanical watches to quartz. I have serviced and fettled 2 x ESA 9154 and a Citizen Cosmotron and I like the electronic aspects. What would be a good, serviceable, quartz movement to start with? -
Well I would think that depends on many factors. This was the same Potence clip my father made when he attended the Bulova School after WWII, so maybe it's just that different places teach differently -
I said it was a learning effort...I learned a TON!!! It was a great learning effort. Your time was much appreciated and led to a much deeper understanding on my part of many many things. I'm sorry if what I said gave a different impression. When I said it didn't work out, I meant in the sense that I wasn't able to repair the problem on the pocket watch I'm trying to service! More later... 😁 -

Here are the photos of the mystery watch. Grateful for any help with identifying it. Thanks everyone. Your knowledge is invaluable -

Checked already it is 1.9mm. Meanwhile I came also to the same conclusion that the MS I am looking for is numbered as 2230 which is 2.05 mm in height (and made in different strengths), that's the reason why I double checked.. maybe it is the correct height. The barrel lid is actually not the press in type but the one which sits on the top so maybe the 2.05 what we are looking for. I put the barrel arbor and lid together and I think the gap and the 1.9mm adds together to 2.05mm: 2230 here which is for size 0s & 3/0s: https://pocketwatchdatabase.com/reference/mainsprings
