Abel's Flightmaster had the same issue with a melted gasket . . .
. . . which was resolved satisfactorily initially. My watchmaker cleaned the residual goop by hand; unfortunately, he didn't have the tool required to remove the GMT crown, so when he was ready for final assembly he placed the case with the crown attached in his ultrasonic cleaner, removing the original blue paint. I had to find correct paint at a hobby shop to restore the crown to correct condition.
I don't have pics in my files, sad to say.
