I'll get some pics tomorrow if you don't mind, I'm working all day and at night this week! Got a deadline to meet....
If I was going to rely on one watch to do all, near the sea....I doubt that I'd rely on a rep. I'd get an automatic gen like a seiko diver, steinhart, used oris etc. Watches that have actually been tested to destruction that you won't have to worry about ruining or falling apart in some way. I only see reps as bit of fun,I don't expect them to perform or last like a gen.
Just my 2 cents,of course
