Foggy amphibia? Oh no! (Good ending and interesting rotor pic)

    This is a cross post from the WUS forums - basically how I'm now interested in finding out how to disassemble mechanical movements (tiny screws are fun!):

    Hey guys,

    So Tuesday morning - after a nice hot (but not that hot) shower I check my lovely blue GMT amphibia and to my horror I see a smudge...on closer inspection the "smudge" was on the inside of the crystal and reflecting all the rays of the rainbow back at me. Identified as condensation I immediately broke out the toolkit.

    On disassembling the watch and fearing for the worst I was greatly relieved to see that there were no identifiable water ingression marks on the main seal nor on the movement. The crown (which, as a diver I always remember to screw down) did show signs of rust though. Luckily the rust only entered as far as the outer stem...it seems to me that minor moisture had made it through into the watch and an airing out will suffice. Considering the stem had rusted but the movement seemed to be in perfect shape was a big relief.

    I wrote to Dimitry at Meranom and he was very apologetic, I explained in order to save us both time and expense that a new crown with new seals would be all that I need (vs shipping the watch back to the factory and waiting for it to be returned to me). A win-win situation that Dimitry was kind enough to agree to.

    Of course this post wouldn't be enough without photos so for your viewing pleasure - a(nother) disassembly of a Vostok amphibia:

    Pretty condensation:

    The bits and bobs (see partially rusted stem/crown):

    Amphibia's secret sauce - big seal vs normal puny seal (which sheared by lateral force on the watch I removed it from...something else that doesn't happen with Vostok's design):

    Additionally I have a Meranom SE plain amphibia - inside you find the newer/nicer Geneva striped rotor:

    The rotor also turns easier than the one in the GMT but the second hand is nowhere near as smooth as the GMT one.

    Lovely little watches and I wear them in rotation constantly :)
    Great communication by Dimitry also!
