I just got a Pathfinder PAW 1500T and the book I got with it is marked Module No. 3070 (B). I don't know how often Casio changes their printing and most everything on my watch is in the book EXCEPT for the Tide chart. This little wave is at the bottom of the watch and part of it will flash every second in sync with the flashing counting seconds as well as a traveling around the dial second small square. The wave will change in part due to the time of day and I assume has some real meaning. I live about 400 miles from the ocean so it is more of a conversation piece for me.
Also I don't see any real battery indicator as is shown in the book.
Any thoughts would be appreciated. Thanks, Tom
