My Cal. 52

Dear Masters of the Clocks :)

I dug up an IWC cal.52 1917 with movement 665683 h6 and case 470539.
Unfortunately the piece is running really slow, being slow by about a minute per hour.
Now, I know that one can tinker with Jones (though not exactly sure how you go about that per se) and adjust the slow/fast issues, but I have a feeling that a minuter per hour is a bit much and that something is mechanically wrong with the piece.



Now I would love any advice or estimate what could be wrong and how much will it cost me to fix it.

thanks! :)

There's nothing wrong with your watch, that a good cleaning and oilling wouldn't fix :-)...Any qualified watchmaker can do that for you, and the price will be negligible.

Agree 100% with Jimmy.

You have a very nice example there in a beautiful niello case.
