Unlocking watch

It's not just on a second longpress - double-tapping any button (without the light button) will unlock the screen.

True, but still is bothering.

can happen in training at least to me

What training do you do that can double click that fast on the same button?

I think that it is a brilliant feature, impossible to do by accident and quick when you want to unlock.

It was in crossfit exercises and it doesn't have to be the same key... its just need to be quick. Press down button and then up-menu button and it will happen.

I dont say that it happens all time but it did and i thought i should mention it.

Wich FW Version are you on? The way you describe it, it was handled in FR945, Fenix 6 generation. 
On FW 7.2 and above, it only unlocks when you push the HotKey again or double tap fast. 
if I push the same button once fast and then once long, mine will not unlock. 

Epix Gen 2 FW 7.24. Try to push down button and fast the up-menu button when device is locked.

Create a Hotkey using two buttons eg Start+Up. That should get around any tendency to push against a button

Unfortunately that doesn't help. You can still push two buttons (any) quickly in sequence to unlock.

at least it does vibrate and show take some time to unlock - but you are correct - a double press shouldn't work, as watch states it should be long press only - I suspect it is something to do with the torch double tap on the light button.
