Making a splash at CES last week, Smartlet is an unusual product. It’s a modular strap that lets you wear a smartwatch and a mechanical watch simultaneously on the same wrist. It works with most name-brand smartwatches and fitness trackers, with any watch from 18 to 24 mm lug width. One goes on top of your wrist, the other below. Designed in Paris, it’s built for people who track their health but don’t want to abandon style.
