This is just my own view.
I find Vianney atrue artist. In 1998, he puts out the very first watch that carries his name, the Antiqua, which is still in great demand and is still being made.
In 2000, the Goldpfeil Camera watch, so difficult to grasp...and priced at 4x the cost of the other AHCI in that group. Today, the watch is growing into a cult item...but not before it was unwanted and sold at 50% discount for 6 years. That watch, is an awesome work.
He released the Classic to pay the bills....and it is and will be the only affordable Vianney...and he prices his work too low..in my estimate.
Then there is one variant of the Antiqua, the rare Contemporaine. And the rare variant of the Classic..the Janvier..all not affordable to the mass market.
The Trio was a watch I had followed early in its conception. A very pure work from the soul. Not easily liked or admired for beauty from a glance or even after months of thought. But later it flows. The beauty of the watch is inside the form itself.
Vianney remains very true to his art..he makes a watch like the Trio and the Antiqua and the Goldpfeil...all not acceptable to the market , the mass market...but lasting in form and expression. These watches are beautiful to possess. To understand them, it is another beauty, something that only the owner gets to keep...and feel.
I don't yet own a Trio..yet...but I feel that it is like the Antiqua.
It took me 3 years from 1998 to understand the Antiqua (halter Barnes), and 2 years to understand the Goldpfeil, I recall, that in the days that I bought them...most of my friends, who were really serious collectors, also had great doubts about the form, and the "beauty"...today..the same folk also own these watches.
The Trio is TRUE art. Totally non commercial. Not done to please anyone but Vianney's vision. Vianney's new model output is very very small.
