.. on overall impression and appeal.
Personally, I absolutely love the black dialled versions;
to me they stand for dark strength, but still balance and attraction.
Also - if one takes the 2012 editions shown in the first pics, I have the feeling,
that this illusionary thicker bezel (?) because black, and increased contrast
makes a bit like nice "bully boy", although not at all
loosing charm or silent strength..
A cooler, more powered look, whereas the 2012 editions, as well in ss,
as in RG deliver more the DNA of subtle elegance.
And yes, it is quite different to my eye.
+1 on your statement that the implementation of another
case, such as the MUT or such might deliver a refreshing face-lift..
Finally, I always think with JLC, the entry model(s) not always are
the " best bang for the buck", as by spending a bit more, might get you
into the realm of another appeal.
I always have loved JLC for having had resonably prized offers,
with some nice " simple" complication and/or indication..
Such examples may have been executed in the Master Hometime,
or the Master Reserve de Marché, (AFAIK)..
Just my little 0,02 cents
Best, hs
