Did anyone try diving on drysuit with a Polar bluetooth H7 heartrate monitor and Polar Loop activity monitor worn on the wrist ? I was wondering if it works . . .
 
Iit's more a question of: how long will it work or how deep will it go before it cracks?
 
everything is worn inside the drysuit, it has to work, only way to find out it to give it a try

To me, it's more of a question of "Why bother?".
 
Even in a Drysuit it's subjected to pressure. You might want to check the manual to see if it's rated for any level of water resistance, but you are right - there's only one way to find out for sure.
 
Some of the Polar models are rated water resistant to 30m which really only means that they're rated for swimming.
It's mentioned it will be worn inside the dry-suit - so unless you have transparent panels in your dry-suit I assume that means that you can't see it during the dive and it's only for logging purposes.

Note that the problem with a watch under these circumstances is more likely to occur on ascent. The seals that I have seen on this type of watch (metal backplate with 4 screws) are usually fine while the external pressure is higher than the internal. However, the air under pressure inside the dry-suit is quite likely to penetrate into the watch during the dive (seals are better at keeping water out) leaving the watch pressurized at depth.
Then as you ascend the internal pressure will exceed the external pressure causing loosening of the fixing screws. The watch may no longer be water resistant after the first dive.
