Hello,

Very new to this so please excuse the newbie question! Have recently purchased a Mira 17 jewel manual wind watch, seller said (I think) an ETA movement? Anyway picture attached. I want to remove the winder stem, so I can take out the movement to clean some dirt trapped on the inside of the crystal. How is the winder stem released? Please describe in relation to attached photo. Thanks, Brian C

Hi The movement is an AS/ST caliber number under the balance rim.  To remove the stem going by your picture from the crown move left there are two screws the small one nearest the stem is the release screw, back it off 1 1/2 turns this should release the stem.

I was unable to determine the brand as I was couldn't find the symbol under the balance (AS ST). Perhaps an Adolph Schild of some sort? It's not an ETA but I wouldn't be surprised to learn it is a fine Swiss brand.

This is likely the setting lever screw. Unscrew it in in small steps (a quarter turn) and the try to pull the stem. On some movements you may also need to push the setting lever screw down a bit while pulling the stem out.

Good luck!

Thank you so much! Job done. Nothing so annoying as a speck of dirt under the glass in my opinion!

    • interesting video nice to see the machine what it can do now I wonder what it costs and I'm sure it's not in my budget. Plus the video brought up questions but the website below answers the questions? What was bothering me was the size of his machine 4 mm because I thought it was bigger than that? But then it occurred to me that maybe they had variations it looks like four, seven and 10. With the seven and 10 being the best because way more tool positions in way more rotating tools. Although I bet you all the rotating tools are probably separate cost https://www.tornos.com/en/content/swissnano   Then as we been talking about Sherline. Just so that everyone's aware of this they have another division their industrial division where you can buy bits and pieces. I have a link below that shows that just in case you don't want to have the entire machine you just need bits and pieces. https://www.sherline.com/product-category/industrial-products-division/   Let's see what we can do with the concept I explained up above and bits and pieces. For one thing you can make a really tiny gear very tiny like perhaps you're going to make a watch. Then another version the center part is not separate it is all machined from one piece. Then fills gear cutting machines have gone through multiple of evolutions. A lot of it based on what he wanted to make like he was going to make a watch unfortunately eyesight issues have prevented that. Another reason why you should start projects like this much sooner when your eyesight is really good or perhaps start on watches first and then move the clocks then local we have from the industrial division? Looks like two separate motors and heads. Then it's hard to see but this entire thing is built on top of a much larger milling machine as a larger milling machine gave a very solid platform to build everything.   Then like everything else that had multiple generations are versions the indexing went through of course variations like above is one version and the one below was the last version. Now the version below I mentioned that previously and somewhere in the beginning to discussion and somebody else had one in their picture. As it is a really nice precision indexing. Then I wasn't sure if I had a the watch photos here is his unfinished watch. No he wasn't going to make a simple watch like none of his clocks were simply either what would be the challenge and that.    
    • Use a Portwest Howie lab coat. They are the biological type so they have tapped cuffs so you don't end up getting the loose cuffs of normal lab coats catching everything. 
    • Some of the Chinese tools ae great and can be purchased at a fraction of the price of Swiss ones, some are complete garbage and some I'm convinced are coming out the same factory as the branded ones.
    • I found this string about this problem. I've not gone through it all, but I believe it also mentions making a spring. If not in this string, the info is online.
    • No, I now realise it’s broken😥 ive looked for one online, but v. Expensive! im going to service as is, in the hope that  one turns up. Thank  you.
