I once had the pleasure to try on a Vacheron Constantin Tourbillon watch in their Zürich HQ. I was dressed as a tourist, but the store staff was gracious enough to not look down on my clothing. Supposedly each shop only have a few, some may have as low as one or none, because there are so few of them made each year. It came in a big beautiful wooden box. That Tourbillon watch was a piece of art. It 'only' cost around 120k USD in early 2000. No, sadly I didn't come home with it. I still dream about that watch once a while. Need to win a lottery first.
