Great watch. This is my 3rd Eco Drive. First one is over 25years old and still runs perfect, so I wouldn’t put much stock in the “only good for 4-5 years” review. I love the size and the readability. It’s a little different to set, but once you read the instructions and figure it out, it makes sense. I like this model better than the other two because you change the mode with the crown. The other ones used the buttons and sometimes if you were working on something it would end up in chrono mode. The citizen eco drive is a solid watch that has served me well. Recommend this to anyone. Titanium is nice because so much lighter.
