same watch, different colour

[Ozmira]

I've found a watch that im thinking about buying but i'm stuck. i'm currently looking at 2 christopher ward c13s. c13swt and c13skk. i'm thinking about just getting both but would like to know if anyone else has been in my position before and what have they done about it.

any help would be great.
