The only issue I have with the crown operation is the twist fast or slow function. For example, if I wanted to change the 2nd time zone one hour ahead, I have to twist the crown fast. Sometimes its hard to do on the wrist. But overall I like the simplicity of having one crown.
The bracelet is the newer 'professional 2' and is part of the newer Aerospace Avantage. I like the way it looks better than the previous generation.
