Apple Watch Blue tooth connection issue

[skideeppow]

Question, I had an Apple Watch Ultra and when I used it in the water when kiting or winging, my blue tooth headphones would disconnect when it went in the after. 
On older Apple Watches, when the watch came out of the water the headphones would automatically reconnect. 

This would not happen on the ultra, I would have to unlock the watch and the manually reconnect the blue tooth headphones.  I ended up returning the watch because this became such a pain the a$$. 
Does anyone know if there is a setting to allow automatic re connnections with blue tooth accessories, or is it only the older Apple Watches that automatically reconnect.

I would like to purchase a watch that allows me to reconnnect in the water without have to manually do it. 

My wife has the second version of the Apple Watch, it is very old but it automatically reconnnects.

Thank you for your help
