    I am working on a dive watch. It's a one-piece case (open through crystal) and it looks like the seals leaked at some point and there is rust on the movement.

    I removed the crystal and I was able to lift the dial up enough to release the dial screws and remove the dial, but the rest of the movement is stuck in the case back.

    Any suggestions on how to get this movement out of the case. Of course, I want to salvage as much of the movements as possible (as well as the case!).

    Thanks,
    Chris

    You can always try Naval Jelly. It will break down the rust but shouldn't attack the metal.

    Frankly, I wouldn't try that- I suspect that Naval Jelly will attack the plate and bridges of the watch...but then, you may have more experience than I have.

    If it were me, I would try ultrasonically cleaning the watch in kerosene- that should not harm what is left of the watch.

    Thanks for the tips... I think I'll start slowly and move up from there. I'll put it in the ultrasonic with just water and then try some L&R Ultrasonic solution. If those don't work, I'll put out the bigger guns.

    Thanks again,
    Chris

    I've had similar experience with a dive watch. Soaked it in weapons cleaning fine oil over night, then cleaned in zippo lighter fluid. All the rubber gaskets do swell up from the oil, but they were probably faulty anyway. I have also used penetrating releasing oil with success.
