I'm a big fan of the grained dial, but, at the contrary of the Duometre à Chronogaph, there is no white metal grained dial Duometre à Q.L.
So, to me, the only choice is the WG version, when it comes to the Q.L.
But I'm thinking about the Chorongraph, and I'm still hesitating a lot on the answer to bring on this matter.
Will try to take some macros of the black dial, to compare them with the macros of the grained dial;
The Q.L is an " intellectual " watch, hs.
Once you made the effort to understand what's behind the watch, you appreciate it a lot.
What I noticed is that at the beginning of the Q.L life, there were some reserves, hesitations, which disappeared now for a warm welcome, or a strong addiction.
Yes, the Duometre à QL in WG is Hell!
Best, my friend.
Nicolas.
