Bought this watch in August 2012 for use on a trip. The black ion plating and general design of this watch is very attractive and feels very comfortable. I've had many compliments on this watch. The crystal in mineral glass, and is pretty scratch resistant. The back does not have a screw down case, it appears to be a press down type, and it's rated at 50m water resistance. I won't worry about scratches or the watch filling up with water though. Since I had this watch I used it swimming in a pool about 3 times a week, went on 2 camping trips and a couple fishing trips, as well as 3 hikes (one of which was to a waterfall), and this watch shows NO sign of wear or even a scratch. The numbers are silver, and is sometimes a bit difficult to see in direct sunlight, but adjusting the viewing angle usually sorts of the problem. The luminous hands glow really well on exposure to sunlight. To top it all off, this watch has the indiglo back light function, which is a great feature, it is very bright and in darkness you can get the time at a glance! Overall this is a great watch and was an excellent purchase. Highly recommended! See customer photos for the luminous hands and indiglo function!
