I'd prefer that it automatically display the surface interval too, but I really don't miss it that much (especially considering the price of the watch.) I just "listen to my body" to sense when I'm relaxed enough for my next dive. If I'm doing deep dives (for me that's ~70-100') then I give myself ~5 min. surface interval. The watch has a countdown timer, but I haven't messed with that.
Your body will lie if there's some fish action down there
