Hi all, I have a Carrera Automatic Chronograph CV2014.BA0794. I was looking at getting a leather strap for it and was just looking for advise on the below. 1. Will a leather strap fit? 2. Tossing up between the red lining or standard black. What do you think? 3. What's the likely cost including the buckle? 4. Will it detract from the authenticity of this model? Thanks in advance.
