Mizuki, Tech Executive in Japan, shares his experience with Smartlet

For years, Mizuki faced a dilemma that many watch enthusiasts in Japan quietly share: a deep love for analog timepieces, and a genuine appreciation for the practical utility of smartwatches. Until recently, no product on the Japanese market offered a real bridge between the two.

"In Japan, there was simply no product that let you wear an analog watch and a smartwatch at the same time. I love analog watches, but I love smartwatches too."

It is a tension that resonates far beyond Japan. The global wearables market increasingly divides watch lovers into two camps. Smartlet was built precisely to dissolve that divide.

From Sony Wena to Smartlet

Mizuki had been a loyal user of Sony's Wena, a smart wristband designed to attach to traditional watch straps. When Sony announced the end of its Wena service, she spent nearly two years searching for an alternative that would meet her expectations. That search led her to Smartlet, as covered in our Sony Wena versus Smartlet comparison.

"As soon as I found it, I transferred the payment and waited eagerly for it to arrive."

She is far from alone. The question is no longer which camp you belong to. It is how to carry both, elegantly and without compromise.

First impressions: doubts quickly dissolved

Like many first-time users, Mizuki approached Smartlet with a degree of caution. She worried it might feel bulky on the wrist, or that daily use would cause scratches and surface damage.

"Before I started using it, I honestly thought it might get in the way, or that it might scratch. But none of that happened."

She even took an extra precaution early on, fitting an Apple Watch case over the module for added protection. It turned out to be entirely unnecessary. Despite typing at a computer every single day, the surface of her Smartlet Classic remained pristine.

"There are absolutely no scratches. It is in beautiful condition. That told me this product is very well engineered."

This durability is by design. The Classic is crafted in SS316L stainless steel, the same surgical grade alloy used in high end watchmaking, engineered to survive daily life without losing its finish. For those who want to go further, the Titanium version offers Grade 2 titanium that is lighter than steel and naturally hypoallergenic.

The joy of mixing and matching

What surprised Mizuki most was how much pleasure she found in the simple act of swapping watches while keeping the Smartlet module in place.

"Being able to use both an analog watch and a smartwatch is genuinely fun. I have several analog watches, and switching them in and out has become an enjoyable ritual. I change the watch depending on my mood, and use Smartlet to pay by credit card wherever I go."

This is precisely the freedom that Smartlet's patented dual-carrier system was designed to deliver. Any watch with a lug width between 18mm and 24mm connects via standard spring bars, with no tools required, and swapping takes three seconds. A full compatibility guide is available to verify fit with your specific references before ordering.

Turning heads at the counter

Paying with a watch strap is not yet a common sight in Japan, and Mizuki's Smartlet regularly draws curious questions in cafes, hair salons, and shops.

"People always ask: what is that? I explain that it is a product called Smartlet, made by a French company, and that you can buy it on Qoo10. I always hope it becomes more widely available in Japan."

That curiosity is consistent with reactions reported by users around the world. Smartlet has attracted attention from watch media across Europe, North America, and Asia since its debut at CES 2026 and its Bronze Medal at Concours Lepine International Paris 2025. The combination of NFC payment capability, health tracking, and analog heritage in a single metal bracelet remains genuinely unexpected to most people who encounter it for the first time. Maxim, a collector in Prague, describes the same spontaneous curiosity from strangers.

A product that has earned its place

When asked about the current Smartlet lineup, Mizuki expressed genuine satisfaction with where the product stands today.

"The color options are good, and now there is titanium as well as stainless steel. Honestly, I am very satisfied as things are."

The collection currently comprises three distinct expressions: the Classic, crafted in SS316L steel for everyday elegance; the Shadow, for a darker, more assertive aesthetic; and the Titanium, for those who prioritise lightness and technical purity. All three share the same patented modular architecture and the same compatibility range.
