Hello. I've read some reviews of both the Mudman 9300 and Rangeman 9400 in which claims are made that there is water intrusion or condensation in these watch at a higher rate than other G shocks. Has anyone heard of or experienced this phenomena? If there is truth to this, what could be causing it; maybe the sensors? Maybe people are working the buttons while submerged? Or, maybe this is untrue. I'm thinking about a Rangeman 9400-1, so any info will be of aid. Thanks.
