Casio Duro MDV-106 "Marlin" Diver Style Watch. A Complete Collection (Almost)

The Casio MDV-106 "Duro" Diver Style watch was first released in 2011. It&a tough, very affordable watch which fits within the Rolex Submariner Homage category, even though it&a quartz watch. And people love the Duro, which is also called a "Marlin" because of the fish illustration on the face and also on the back case cover. But there&also a new version (without the fish) which seems to be essentially the same. It&the MDV-107. But wait! The MDV-107 appears to be an International release which is just a bit harder to find if, like me, you happen to be in the USA. ANYWAY, I decided to buy all of the versions of the MDV-106 I could find now, just in case they were all discontinued in favor of the MDV-107. Granted, I have no definitive information which says the MDV-106 is being phased out. But, just in case that happens. I decided to get them all.
