TY for the clarification. I can read what folks write, but I cannot read their minds. 
And, yes, diving to depths of 175 feet does require that the watch one wears when doing so have a WR rating of minimally 100 meters to ensure the water pressure won't adversely affect the watch. The reason I cited the things that impair a watch's WR abilities is that those things are in play no differently for a watch having 100 meters worth of WR than they are for one having, say, 300 meters or more of WR. For example, the drying out and cracking of gaskets and seals will happen at the same rate regardless of the WR rating the watch has.
FWIW, I've never had water/moisture enter any of my watches either, aside from when the glue that secured the crystal gave way on my Movado. It's not a diver; it's merely a water resistant watch.
That experience led me to inquire of several other watch companies whether they too use glue to secure the crystal. Every one of them did -- although several of them told me they use "this or that" special glue that will hold up better than "garden variety" glue. I presume most watch companies still use glue.
All the best and dive safely. |
Haha thanks for the kind words and detailed reply back. You're totally right about the activities I mentioned being at sea level of course, but I also live by the assumption that 200m water resistant means better seals, gaskets, and glue then a 10m water resistant watch. There is quite a lot of pressure under 600+ feet of water! That is "heavy water"
That is, albeit in my opinion, a much more hostile environment for the watch than a hot tub at sea level.
