I prefer the Titanium MMR, too.
But I had hard ( and delicious ) time deciding which one I really wanted to pick, between the Titanium , and the Platinum ( with the silver open dial ).
It took me around 14 months to be sure that I wouldn't regret not having the platinum.
So I tried both of them again and again, to finally go on the Titanium.
With the Time I can say that I'm very happy with my choice, for the reasons you perfectly said.
What I appreciate a lot, with the Titanium MMR is the concept wat look associated to such a refined complication.
It is audacious from JLC to do that, and I love it.
But, really, each of these MMR is a very nice Minute Repeater, and at the end, I am deeply convinced that it is a very personnal and subjective matter.
The question is not if but which one to choose.
Best, Respo.
