This was just after I purchased it new in about 2008 or 9. I was stopped in a large country town in New South Wales (Dubbo) it as about 40deg Celcius and I jumped into a pool to cool off, glanced at my new watch and the crown was unscrewed and there was water on the inside of the crystal. I managed to find a watchmaker in the town and he dried it out for me. No problems after that, it has since had 2 services and there have been no problems with discoloration or corrosion and been no mention about water damage inside.

There are a lot of better places to visit in Australia.
I'd think the hydromaniac shock was probably the cause.
Anyway it survived, I'm actually wearing it today.
Hello! I also have a doubt, if for example you forgot to screw the crown and go into the sea or take a shower with unscrewed crown, can something happen? Or does it have extra protection? I am referring to the Omega Seamaster 300m.
So, this question comes up frequently, so here's some photos for the you. Starting with a freshly serviced watch:
Standard pressure test using vacuum and pressure. -0.7 bar vacuum, and +10 bar pressure:
With the crown screwed down, of course it passes easily:
Let's unscrew the crown now:
Test it again, and it passes:
Here you can see that the crown is unscrewed:
Now let's pull the crown all the way out to the time setting position, so pulled out as far as it can be pulled out:
Test it again, and it passes:
The gasket that is inside the crown doesn't leave contact with the case tube, no matter what position the crown is in. No one is suggesting that you should intentionally leave the crown unscrewed on the watch, but if you do and the seals are in good condition, then most likely you will be fine.
There are some people on watch forums (this one included) for whom water resistance is a topic that can't be thought about in any rational fashion. They will tell you that getting your watch wet will result in doom and chaos, but these watches are designed to resist water, and if they are in good condition (this is the key) then they will be fine.
Cheers, Al
I’ve always been curious about water resistance as it pertains to Omega screw down crowns. Based on what you’re saying, the act of screwing down the crown itself does not contribute to water resistance - correct? If that’s the case then I wonder why Omega doesn’t openly state that, similar to how they state the He valve is WR to 50m if left unscrewed.
Would either the 300m or Planet Ocean (non chrono) be water resistance to their full depth rating if the crowns are left open?
Only a stopover on the way to an even more remote place...
But Dubbo apparently has the best pies in Australia (along with the hundreds of others who make that same claim)...
It was pretty tasty...
"hydromaniac shock" there's a lot of that going around on watch forums mate. 😉
