I am blessed to have both (Classic medium Reverso and Rose Gold Tank Louis). They will stay on the collection.
The Reverso is more sporty with a bit of elegance coming from the dial. As such, I can wear it in almost any outfit, from suite to TShirt with jeans.
I just wish it has more water resistance, as it was created as a sport watch.
The Tank Louis, especially in rose or yellow gold, is pure elegance, an utmost beauty of dress watch. So i never wear it with T shirt and jeans. It should be worn with formal suit IMHO.
Both of these will stay as a iconic watches from 2 great
Houses, and likely they will do their best to preserve the original design.
My personal opinion is that The Reverso is more comparable to Cartier Santos Dumont, as a sporty (not sport) watch.
