Hi guys,just wanted to share the results of the test I did today.
Since we had the first snow for this winter last night I decided
to test my g's (and myCitizen Nighthawk) and see if they would fog
under the crystal.
So I took each of them out and put a pinch of snow on the
crystal.The watches in question are G6900B,GLX5600,Mudman 9000
and my only one(so far)froggy-gw200ms1 All 200m rated.....and guess which ones fogged
and which didn't.Well the results were a little surprising to me,because
they all fogged..including the frogman.And since even the frog (which
we all know is ISO certified) fogged I assume that under the same conditions
pretty much any watch will fog.This is the condensation test that any ISO6425 certified watch
must pass : Condensation test. The watch shall be placed on a heated plate at a temperature between 40°C and 45°C until the watch has reached the temperature of the heated plate (in practice, a heating time of 10 minutes to 20 minutes, depending on the type of watch, will be sufficient). A drop of water, at a temperature of 18°C to 25°C shall be placed on the glass of the watch. After about 1 minute, the glass shall be wiped with a dry rag. Any watch which has condensation on the interior surface of the glass shall be eliminated.
I assume that the frog will pass that test ,but my test was a bit more stringent because my "drop" was more like 1-3 °C instead of 18-25.
The fog stain was no more then 2-4mm in diameter on all watches including the frog,maybe a little bigger on the Mudman
and disappeared within 20-30sec. The same with the Nighthawk.I'm not worried at all about their WR because I've
showered and swum with all of them and never had a problem.
But I was wondering if any of you guys have done similar test with other ISO certified watches so we can see if the frog is
