JLC Polaris Chronograph in the water

I own a JLC and I wouldn't go swimming with one, regardless of the WR rating.  I'm just not that brave.

Firstly, I am an Advanced Certified Open Water Diver. No sport diving takes place below 135'. Not if you want to dive any more.

Secondly, watches rated at 100m already (supposedly) greatly exceed that depth. If one were to wholly believe that your watch can and will withstand pressures at that depth, then you should be willing to splash around the pool or the beach with nary a worry.

Lastly, it is your (and only your) decision whether you decide to venture into the water beyond your shower. If your watch is precious and/or valuable enough to sway your decision then by all means, do what you think is in your best interest. 

Also, you could ask your local dive shop if the watches they sell (or recommend) actually hold up under the diving environment 

There is only one way to find out the WR claim😜. I have several watches and on every vacation I only  take my reliable and waterproof watch - Apple Watch.. 

For the love of all that is holy, don’t take your watches into the shower!  As bad as water is in getting into watches, steam is 100x worse.  It invariably WILL get past the seals and gaskets in your watch.

I would not take that watch in the water, ever.

I assume you're talking incidental water, not dedicated diving.  If so, yes you should be fine and no don't use the pushers.

That said, I tend to take far less expensive watches on my vacations that I intend to do something reasonably outdoorsy and if I find myself with a pricey watch, I just leave it in the hotel safe regardless of stated specs.

Takes a braver man, or dugong than I am to take that swimming, but you do you. Just remember not to use the pushers underwater or pull/unscrew the crown and you should be good.

That said...

Brush up my fake shark fin and wind up the cassette for 'Jaws' theme 

😂😛

Great opening sentence! Ha!

Great watch. Not sure I would take it in water. 

I always read their manual about what they are telling, in the manual they indicate that it is safe to swim as far as you keep your watch checked regularly once every two years for its water resistance. But also in the manual as far as i've seen the crown is not a screw-down one. While wearing during swimming you should be careful to not catch the crown to your swim suit or shorts etc. I made it to a citizen and it was already dead when i've realized it. 

But anyways, pool water and sea water will start to remove the shine of the watch and somehow causes a lot of micro scratched. Are you sure you want to wear your over 10K value watch while swimming?

I think the critical issue would be water or steam 'under pressure'. Wearing your watch in the shower or into the steam room (in my opinion) would not necessarily be enough pressure to breach the crown, seals, gaskets or the pushers on most watches. I will claim ignorance here and defer to experts who have more experience in this matter - perhaps I am categorically wrong. 

I wear my dive watches (with screw down crowns) into the pool, fishing, into the surf at the beach, in the shower, in the steam room and have had no problems. But that's just my own experience. Others may differ.  

Thanks for all the responses! If I buy this watch and wreck it swimming I'll be sure to let you all know. 😄
