Smartlet: One Wrist. Two Watches. No Compromise.

Smartlet : One Wrist. Two Watches. No Compromise.

We all have that one watch — a gift, an inheritance, a reward. But today, we’re asked to trade it for a screen. You love your watch. You need your smartwatch. So why should you have to choose? 

Smartlet is the first bracelet that allows you to wear both a traditional timepiece and a connected device together, on one wrist. It’s the meeting point of elegance and innovation, offering a refined solution to a modern dilemma.

Smartlet is designed in Paris and embodies a standard of French precision and refinement. From materials to finish, it reflects the values of enduring craftsmanship. With Smartlet, we’re not just adapting to modern life, we’re redefining the way we wear time.

Designed for the real world

Smartlet was made to integrate effortlessly into everyday life. Whether you’re working, training, or moving through the city, it adapts to your routine with clarity and purpose.

Imagine this: It’s 8am. You wear your vintage Omega for an important meeting. At lunch, you jog with your smartwatch to track your progress. At dinner, you want to look sharp — but still get that message from your kids. With Smartlet, no compromise.

• Track your health and activity continuously with your smartwatch or fitness tracker worn comfortably on top
• Stay connected throughout the day with discreet access to notifications
• Make contactless payments with a natural, fluid gesture that fits seamlessly into your movements
• Manage multiple watches, classic or connected, with a single modular bracelet that adjusts to your needs
• Keep your traditional timepiece tucked discreetly underneath when commuting, adding an extra layer of security in public spaces

This is a new standard of elegance and utility, designed to reflect the way we really live.

Smartlet looks just as sharp with a suit as it does with jeans or sports outfit.

A vision born from frustration

David, the founder of Smartlet, spent years switching between elegance and functionality. ‘I wore my smartwatch to track my sleep, but I missed my father’s timepiece. That’s when I realised — I don’t have to choose. I can build the bridge.

Mechanical marvels carry identity, emotion, and a unique story. But as the world evolved, so did our wrists. From fitness tracking to payments and notifications, smartwatches and fitness trackers became part of daily life. Yet most of them look and feel the same, defined more by their digital ecosystem than by any real sense of uniqueness. They may be functional, but they lack the emotion and character that define true horology.

In contrast, traditional watches have a soul. They speak of history, craftsmanship, and individuality. But as digital convenience took over, these heritage objects were slowly pushed aside. Smartlet was born from this tension. David began with a simple question: why choose between timeless tradition and cutting-edge technology?

What followed was not the design of another gadget, but the creation of a new category. After months of sketches, prototypes, and refinement, Smartlet came to life in Paris, a city where horological culture meets industrial elegance. The result is a modular bracelet, patented, that lets you wear a classic watch and a smartwatch on the same wrist with balance, intelligence, and style.

From idea to reality

Bringing Smartlet to life has been a long and demanding journey. From the very first sketches to a fully functional modular bracelet, every phase required precision, iteration, and care. We weren’t just building a wearable, we were developing a new way to carry both time and technology on the same wrist.

We’ve gone through multiple stages of prototyping to test proportions, mechanical integrity, and overall comfort. At each step, we asked tough questions: Is this intuitive enough? Elegant enough? Reliable enough for daily life?

To help answer them, we involved a panel of early users, watch enthusiasts, athletes, and connected lifestyle advocates, who tested Smartlet in real conditions. Their feedback played a key role in refining ergonomics, improving balance, and making sure the product felt natural on every wrist.

Beyond the technical development, we placed particular emphasis on the experience itself. Adjusting your Smartlet, assembling it, changing modules, it all had to feel smooth and satisfying. The included toolset, link system, and adapters were fine-tuned to make the setup as elegant as the design.

We have been back to the whiteboard at several stages to make sure the product would be in line with our  expectations.

A canvas where the past and future can finally coexist with elegance.
