This is coming up again and again (reps and swimming)...
New members please note that the WR claimed by the dealers is just a "promise" that is not to be taken to the bank!
remind yourself where and most important how this watches are made and put together!
Out of the BOX i would not submerge any >REP! Common sense applies... thing to do would be open the piece geese the O rings and the test the watch at a watchmaker for WR.
If you are unable to do the greasing and checking the seals are in place at least go do the WR test TO AVOID disappointment later!
