Sorry guys, I had posted this question on another thread but I think my question was just buried with other responses pertaining to the main thread.
My question is about the GMT watch. Some have a 2 colored bezel and some don't. For example one half is blue and one half is red. Or Black and red. Is a 2 part colored bezel used for anything or is it just for looks? I have heard that it can be used to tell day from night. If that is the case then can someone provide instructions on how that is used?
