    Hello All,

    I just started taking apart a Waltham 3/0 that I got for $12. It’s not working. Take a look at the attached pictures to see why....

    I’m not sure what that gunk is, but it has penetrated the entire movement. It appears someone may have decided to squirt WD-40 in the crown hole?

    Anyway, I’m planning to clean the movement and all parts with mineral spirits, but what do I use to clean the back side of the dial? And, what would the procedure be? (I’m assuming I wouldn’t just dunk it in the solution....)

    Thank you!

    Enamel dials can be safely cleaned using Polident. (Don't try this with painted dials!)

    For enamel dials I usually use dishwashing detergent and warm water. Scrub gently with an old toothbrush. I reserve the Polident for dials that have hairlines or prior repairs for chips done with unknown repair products.
