The Consumer Electronics Show is never short on ambitious ideas, but Smartlet may be one of the more unusual ones this year: a modular watch strap that lets you wear a traditional mechanical watch and a smartwatch on the same wrist, simultaneously. One on top of the other.
The Paris-based startup announced Smartlet at the 2026 CES in Las Vegas, pitching it as a solution for people who love the look of an analog watch but also want the practicality of a smartwatch for notifications, fitness tracking and mobile payments. Instead of choosing between the two, Smartlet's system lets you mount an old-school timepiece on the front of your wrist while hiding a smartwatch or fitness tracker on the underside.

SmartletThe stainless steel strap starts at $418 and doesn't include a smartwatch or a mechanical watch. What you're really buying is the strap system, which is compatible with most major smartwatches and fitness trackers, including Apple Watch, Samsung Galaxy Watch, Google Pixel Watch, Garmin models, Fitbit Charge devices and Whoop. On the analog side, it supports watches with lug widths from 18 to 24 mm, which includes high-end models from brands such as Omega, Tudor, TAG Heuer and Rolex.
The idea comes from founder David Ohayon, who says he was tired of having to play favorites every morning, choosing between his analog and Apple Watch. Smartlet, in theory, offers the best of both worlds, letting you toggle from fitness nerd to polished executive with the flick of a wrist.
In practice, it raises some serious questions, the biggest one being bulk. Smartlet says the system adds between 9 and 12 mm of height to the underside of the wrist once a connected device is attached. As someone who already manages to scratch watches without trying, the idea of strapping a second device to the underside of my wrist, where it regularly comes in contact with desks, armrests and tabletops, sounds like a walking nightmare.

Smartlet is clearly aimed at what it calls the "modern gentleman," with marketing language that leans heavily into luxury watch culture and phrases like "from the boardroom to the weekend." Translation: This is a watch for wealthy men who want to show off their investment piece without sacrificing their gym gain tracking.
And while it may not be the most practical, or budget-friendly solution for most people, Smartlet is one of those highly niche, standout products that had us doing a double take at this year's CES.
