Well I wore a Casio Pathfinder until about a week ago when the battery went dead and I tried to replace it myself and it didnt go so well. I thought that I wanted a Luminox but when I went and tried one on the thing was so small comparied to my casio. I watched a video on youtube that said the Luminox colormark was the same size as a Pathfinder. Not so in my opinion. So I'm still looking.
