Hello, Nice watch very comfortable to wear. It is waterproof, enough anyway to support swimming and diving jumps (the "shock" at the time of entry into the water can be fatal). No not under a hot shower problems. Note that the nylon strap will take longer to dry than a conventional plastic or metal bracelet. This is a very slight wrist watch and all is forgotten easily that it is very "flat". Chance or not I do not know, but the precision of mine does not vary more than a second per month. Its only flaw? It causes! I am not a hyper-sensitive to the "leaf", but surprise! Even while driving in my old diesel 4x4 I hear! tick, tock, tick, tock! Even the watch 3m asked me as I watch tv bother me! I had read this critique and I was also told "there .. They exaggerate." Oh no! It really is his only fault, I love but do not wear it because of that. I therefore advise only if you think the noise will disturb not ticked you, because believe me .. because it !!
