Who knew something so tiny could elicit such a massive response?

Within minutes of my posting a wrist shot of Cartier’s delightfully small new Tank Louis that the French maison unveiled in Geneva at Watches & Wonders earlier this week, I was inundated with uniformly enthusiastic DMs. “Thissss one,” one friend wrote. “I want,” chimed in another. More than a few asked the most important question: What was its MSRP? When I told a colleague the E.U. price was set at €6,500 (just over $6,900)—a lot to ask for a minuscule piece of gold, with a quartz movement, no less—he didn’t hesitate. “10,000% buying,” he typed back.
