I used my non-waterproof Leitz Trinovid 7x35s for many years in all kinds of weather without any issues whatsoever, though I never dunked them in a stream or lake. I guess the question is, is the dunkability issue worth an extra $1,000 to $1,500.00?

Of course you could buy a pair of Zen Ray EDIIs and have great optics in a waterproof package for less than the cost of a pair of SEs.
