I have the Rip Curl GPS watch and found it too hard to read especially at night. So I changed back to my old trusty old Seiko Divers Auto watch. It can be read in the middle of the night in bed and never needs a battery charge or charge up.
I go surfing to escape technology

No, the steam-in-the-shower is a myth.
The damage comes (on the long term) from the temperature changes, by contraction/expansion of the pieces and joint, and promoting local (tiny) condensation in some places inside the watch on cooling.
Granted, this also happen in normal use by getting in and out cold water during sessions, there is just no need to also add stress by hot showers.
This is similar on why you do not let dry a wetsuit in the sun, even hough they are exposed to the sun while SUPing.
How is condensation produced?
