The Consumer Electronics Show is never short of ambitious ideas, however Smartlit Perhaps one of the weirdest things this year: a modular watch strap that lets you wear a traditional mechanical watch and a smartwatch on the same wrist at the same time. One on top of the other.
The Paris-based startup announced the Smartlet at CES 2026 in Las Vegas, pitching it as a solution for people who like the look of an analog watch but also want the practicality of an analog watch. Smart watch For notifications, fitness tracking and mobile payments. Instead of choosing between the two, the Smartlet system lets you mount an old watch on the front of your wrist while hiding a smartwatch or fitness tracker on the underside.
The Smartlet Band at CES 2026 links your fitness tracker to your analog watch.
The stainless steel strap starts at $418 and does not include a smartwatch or mechanical watch. What you’re really buying is the band 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 like Omega, Tudor, TAG Heuer, and Rolex.
The idea came from founder David Ohayon, who says he was tired of having to play favorites every morning, and choosing between his counterpart and the Apple Watch. In theory, the Smartlet offers the best of both worlds, letting you switch from fitness nerd to polished executive with a flick of the wrist.
In practice, it raises some serious questions, the biggest of which is the biggest one. Smartlet says the system adds between 9 and 12mm of height to the underside of the wrist once a connected device is attached. As someone who has already managed to scratch watches without even trying, the idea of strapping a second device to the underside of my wrist, where it regularly comes into contact with desks, armrests, and tablets, sounds like a walking nightmare.
The Smartlet Band is compatible with most major brands of smart watches and luxury watches such as Rolex and Tag Heuer.
There is also the aesthetic. Smartlet is clearly targeting what it calls the “modern man,” with marketing language that leans heavily into luxury watch culture and phrases like “from the boardroom to the weekend getaway.” Translation: This is a watch for wealthy men who want to show off their investment chops without sacrificing tracking their gains at the gym.
And while it may not be the most practical or budget-friendly solution for most people, the Smartlet is one niche, premium product that had us doing a double-take at this year’s CES.
