Your former Chronometre Royal makes me salivate. I got it bad and that ain't good. That black dial automatic is a pure beauty. It is always such a disarming pleasure to see black dials on vintage V&Cs.
Now, as for the Historiques models...I know you have it bad for the Toledo 1951. Understandable.
But the Aronde 1954 is the one the does it for me between those two. I had a chance to try one on a couple of weeks ago (I think the first time I actually had one on my wrist).

Sorry for the poor photo, but my hands were shaking a bit trying on this beauty. :-/
The Aronde is just unbelievable. The dial is out of this world. But...to paraphrase Cyndi Lauper's lyrics from "Kinky Boots"... the Sex is in the Case.
I have long considered the 1955 Ultra-fine the best two-hand dress watch on the market. I still have found no evidence to contradict that assertion.
I think you are right, Bill. The 50s decade was a sweet spot for Vacheron & Constantin. With Les Historiques we can relive the best of the 50s.
Best,
