: Looked ok to me. An 1153 is quite a thick watch, thicker than you
: might expect if you've not seen one in the metal. There is a
: sort of extension of the case at the back, then the caseback
: itself and it all adds up. With its piggybacked chrono module,
: the Cal 11/12 isn't the slimmest movement either. Automatic
: chronographs rarely are, there's a lot of mechanism to fit in.

Thanks Mark, I hadn't expected them to be that thick, compared to a 2447 it looks huge! Even thicker than a modern Carrera I'm guessing...
