Was an old Casio customer since Casio F-5 model came out around (maybe) 1980 up until September 2010.

I started to need a watch with larger numbers so when I was out on missions :-) I was able to see the numbers under intense desert sun light. I was not sure about purchasin a SUNTO however the SUUNTO watches had so many unnessesary features for me based on my military work.  After long search found this one and starting with the HYDRATION, COMPASS and being able to track 3 diferent time zones it set this watch apart since the price makes perfect sense.
