Hi all,
I've allready asked this Q before some time when I was waiting to finally get my Core Y/B.
Now after 3 months of intensive use I can proudly say that I'm very satisfied with it, alti-baro mode is very good and precise |>, compass is correct and finally I've manage to get it after pool test to real sea diving test.
So how deep can it go? Well, I'm sure that it can go up to 10 000m but the only problem is that it (probably) won't work yafter that never more :-!
First I've take the watch to some shallow snorkeling (7-8m) and the measurments was fast and correct. Great job Suunto guys.
It was time to go to the watch limit of 10m that was bothering me trough last 3 months.
In that dive I was carefully monitoring the depth meter and with great scepticism at 9.6m I didn't expect that I'll get any deeper measurments.
But it did!!!
I've stoped at 11.6m and I was SOOOO happy that I can go deeper and that watch will still be correct in measurements.
But than I was suspicious again cause I didn't know how much deeper can I go and still get the depth data.
So I went again.
Everything went fine untill 12.00m.
The display instead of numbers have shown only " - -!" lines and that was it. I continued to go for 2 or 3m deeper and hoping that it will show again the depth. But it didn't....
So when I get back at surface in upper display was "MAX DEPTH 12m" and that was it, U can't get any measurements under 12m.
Now I know what this watch can do and I will still go diving with it up to 20m and I hope that it won't leak.

I was sad but still with this minus i can warmly recommend this watch to everyone.
:thanks
