Over the weekend, my sister-in-law texted me that a friend’s high-school-age daughter has been wearing her mom’s vintage Cartier watch because of the phone ban. Even 17-year-old influencer Allegra Pinkowitz — who tells me that at her school, a lot of kids turn in fake phones every morning so that they can keep clandestine access to their devices during the day — has noticed many of her friends buying Shark watches and is thinking about getting one for herself.
