Hello! I just received an old Wakmann aircraft clock and when I opened the package, the two dial screws holding the dial in were loose. It should be a relatively easy fix to screw them back in, but my issue is getting access to the dial. I believe these old aircraft clocks are front loaded. I removed the retaining ring around the crystal/glass, but from there, I'm not able to remove the glass. Any suggestions? I tried to get something in between the glass and case, but chipped the glass and definitely don't want to damage anything further. It should fall right out, correct?

Look on the back side of the case and see if you find any screws which are used to hold the movement in place? Then depending upon what the gasket was made out of the crystal may be stuck you have to figure out some way to pull it out without angling it because that would cause of the ship it be easier if you just push it out somehow possibly when you gently pushing the movement out.

Well done. With something different it always pays to give it a good look over before trying to take it apart. Dirt plays a big part when trying to take some things apart and also glue, many people like sticking things together, they don't think that it could be impossible if another person needs to repair it.

    • Agreed. There are many different automatic winding mechanisms, each with their own quirks wrt. lubrication. Access to the specific service instructions is the ideal. Otherwise, ask here for advice on the movement you are working on.
    • I put the original broken glass (whats left of it) behind the acrylic. This is how it originally looked like. A cheap clock but I like it. Very noisy when the alarm comes wake up guaranteed! 🙂
    • If at all possible, find a service guide for the automatic movements your work on, because the lubrication procedures may have different requirements or rely on oils you would not use in a manual wind train (in addition to the braking grease you mentioned). Some autos like older Seikos do not have a manual wind option, so the procedure of letting down the mainspring without being able to use the crown may require a screwdriver in the ratchet wheel screw and great care. Do you have an auto movement you were planning to start with?
    • I am an amateur, so there's that. I do not get fixated on amplitude, lift angles, and beat error. However, 4.8ms would bug me if it were my watch. But you must judge your own skills to appreciate the possibility of going backward. I suggest, that you button it up let your friend enjoy the watch for now. As your skills progress, come back to it and correct it. I assume that this watch has a fixed hairspring pin. Some modern watches have an adjustable pin along with adjustable regulator. These are trivial to get in beat. I own a valjoux 726 my dad gave me on my 18th birthday (a looooong time ago). I broke the ratchet wheel with an aggressive wind 4 yrs ago. I have been waiting for my skills to progress before doing a service. I am close. Your advice is well placed and I will apply it.
    • I didn’t find any anomaly to the left of the red mark…reflection? this is the balance in its pivot in the inverted assembly. i can’t see any obvious kinks  and the spring is flat as far as I can see. Either the stud screw is missing, or it’s glued in… I don’t know. I’m loathe to fiddle with it. Any further insights? Thanks!
