The one on the left is a Viceroy and the one on the right is a standard 1163. I know very little about these watches so someone might be able to answer your question about the bezels.

And thanks so much Arno for taking the time to answer my question

So are both of these pictured Viceroys? Arno's post says that the
: Viceroy was based on the 1163MH but with the Siffert Tachy
: bezel. Both of these have the Tachy bezel. Or was the 1163
: available with the T bezel but with black/white dial?
