Hello *,

I was trying to service my first ever travel watch and during re-assembly I noticed that the head of one screw is missing. I have not removed this screw before it went for cleaning and I have no idea where the head is (not found in the cleaning liquid), not like it matters now. Is there any way to remove the remain of the screw?

Best regards,

Lui

If you remove every screw from the movement plate you can put it in alum . There is several threads about it on the forum. 

Thank you. I tried to search first but i was not sure what the methods are. Never heard of alum but I am going to learn about it now.

Will you post a pic of the other side? You may find the other end of screw sticking out so you could grip it. You are going to strip down the movement anyway. Use of penetrating oil always helps unscrew the broken piece, sometimes by a needle or screwdriver, not to mention special removal tools. 

Chemical disolution is the last resorts,  you need to know the plates metal type or alloy to avoid it's distruction by alum.

It was not sticking out, however I was able to gently push the edge of the remain with a small 0.6 mm screwdriver just by the fraction of a mm at the time. Took about 20 mins but managed to get it out. What a relief. :) Thanks for the comment.

      Typical and max diameter of faceplate for 8mm WW lathe?

      By mbwatch · Posted

      I will email them to ask for an accurate measurement; they held an in person lot viewing a few days ago that I could not attend. There is so much I don't yet know, I could not assume that no 8mm lathe exists with a spindle height >50mm.

      By the way, I opened my watch, looked under a magnifying glass, there is simply no grease, the screws are without traces, the slots are intact.I think it's just a matter of maintenance.there are no rotor marks on the body. And to remove the strap from yours, just press on the 1st side,and slightly move the strap, then on the other side and it will come off.

      Hi My name is Chris. Just started trying to learn about watch and clock repair as a result of repairing my fathers old 1890s police station clock (about a year ago). The clock was Ok, but having graduated to pocket watches and then wrist watches, despite the really excellent stuff on Youtube, I am struggling a bit.  As a retired engineer, I find the engineering exquisite, but a bit on the fiddly side.  I have done a few practice watches with a little success but failed a few, but have had success with Seiko 7005s, 7009s etc, but have just attempted a citizen 5430.  Nightmare.  My wife thought I had found religion as I spent so much time on my knees with my eyes to the floor looking for springs.  Got through that and found that the balance is shot.  Trying to source one or something that will fit from the citizen range has me totally perplexed.  Tried Ebay, Cousins etc without luck.  Any advice as to alternatives that will fit or alternative sources would be gratefully received.
