The manual was bent like this by the previous owner, and the tin is here, but not the box.






I have no real need for a tide graph, but I am always appreciative of inventions and technology, so I think it is cool. I do like the moon phase info though.
I love the dual stopwatches, I start one when I head out on a walk, then use the other to time specific areas. the watch face shows progress of both in a small window that is really useful for a quick ballpark time estimate. the 1st stopwatch also can use a 5 second lead in with audible tones, great for timing yourself.
I also love how this watch has an indicator for each alarm, not just one overall indicator.
the timer can be one time or repeat, and it has count down notifications, which I love.
the alarms are multi-function, so much more flexibility than my other watches.

Solar/Atomic (Love that feature)
this watch does have a timer, stop watch, alarms but using those features are not as pleasant as on my other watches.
