    Cause for concern? Doing some pressure testing.

    I had my EZM13 submerged in my pressure tester at 6 ATM for about 45 minutes. Removed it, warmed it with a hair dryer, and then put some ice water on the crystal. There was condensation under the water droplet, but it dissipated quickly once I wiped it dry.

    The copper sulfate capsule is still a very pale blue, about the same as it's always been.

    Should there have been any condensation at all if my seals are intact? By comparison, I performed the same test with my Seiko PADI turtle and had no condensation at all.

    Iím no watchmaker but ANY condensation inside of a watch is not good under any circumstances. The moisture will cause components to rust. The fact that your capsule is still the same color kinda furthers my sneaking suspicion that the cooper sulphate an AR gas filling is not much more than marketing gimmicks.

    Iím sure somebody with more knowledge than I can chime in but I would send the watch in for a service.

    Yeah, I didn't think so. Fortunately it's still under Watchbuy's warranty. Thanks.

    Unless your watch was sealed in something like a nitrogen-only atmosphere in a glovebox, the air trapped in it will contain the same proportion of water vapour as was in the workshop atmosphere that day, to which you can add the watchmaker's respiration and perspiration.

    I suppose these places are generally air-conditioned, so there shouldn't be much water vapour content, but cooling the watch down enough will definitely condense that vapour. It will evaporate as soon as the temperature of the watch goes up again.

    Well, it is an EZM13, so that's exactly how it was supposed to be manufactured, i.e. nitrogen-filled.

    Yeah.... that doesn't sound good to me. I would expect the nitrogen inside to have purged any water as you've said. If it were me, I'd send it in, ESPECIALLY since it's under warranty still.

    Cause for concern? Doing some pressure testing.

    Oh man, Iíve been contemplating getting an EZM13 and this kind of scares me. Is the technology they use in that watch really significantly better than the one found in my $245 turtle?
