Exactly what I needed — without realizing it

Before Smartlet, I had a bit of a weird habit: I used to wear two watches.
A smartwatch for the functionality… and a mechanical watch (or bracelet) for style.

Obviously, it wasn’t ideal. Not always comfortable, not always great-looking… but I didn’t want to choose.

That’s exactly why I backed Smartlet on Kickstarter.

And honestly, it delivers.

Now I finally have a single setup that does both: function and style. I keep the pleasure of wearing a real watch, while still benefiting from my smartwatch features.

What surprised me the most is how natural it feels to wear every day. I expected something bulky or gimmicky… but not at all.

It simply replaced the way I wear watches.

If you’re someone who doesn’t want to choose between style and tech, this is clearly for you.

E.g. Rolex Submariner + Apple Watch, Tudor Black Bay + Whoop...: Omega Seamaster and Apple Watch Ultra

Perfect for my Omega and Apple Watch Ultra

Got it for a couple days. The packaging is nice and well protected. It took me about 30 minutes to setup and adjust for size. Now I can wear my Omega Seamaster and my Apple Watch Ultra together.

It does took couple of tries to figure out the best way to claps the band with all the weight. I am getting better at it every day.

Keep up with the good work.

E.g. Rolex Submariner + Apple Watch, Tudor Black Bay + Whoop...: Panerai PAM177 and Garmin Venu X1

Works great with Panerai PAM 177 and Garmin Venu X1

I got the Smartlet over a month ago and have been using it ever since with a Panerai PAM 177 and a Garmin Venu X1. Both are 24mm and first I had to add my own adapters from 22mm to 24mm, it wasn't the prettiest but it worked. Now I got the 24mm and finally the look is great.

Keep it up.

Amazing!

’ve been wearing Smartlet for a few weeks now, and it’s honestly changed the way I use my watches.It’s one of those products you didn’t know you needed until you try it. Thanks David !

E.g. Rolex Submariner + Apple Watch, Tudor Black Bay + Whoop...: Rolex submariner with an Apple watch 11

E.g. Rolex Submariner + Apple Watch, Tudor Black Bay + Whoop...: Breitling Aerospace + Apple Watch SE 3

利便性と快適性を実現、そして所有欲を満たしてくれる素晴らしいプロダクト

元々アナログ時計が好きでしたが、一方で、スマートウォッチの利便性にも惹かれていました。

2025年1月、偶然SmartletのWebサイトを見付けて、これは良い！と思い、即購入予約をしたのが懐かしいです。

Smartletを使って4ヶ月になりますが、もはや私の生活の一部、毎日に欠かせない大切なツールになっています。

これまでにないスタイルであるため、実勢に使用するまでは不安もありましたが、装着は非常に簡単で、外れたり痛かったり、邪魔になったりすることもありません。時計を2つ着けていること忘れるくらい、装着感は非常に良好です。

万人に受け入れられられるためにはシンプルであることが非常に重要ですが、シンプルだからこそ、美しさと使いやすさを実現することは本当に大変だったと思います。何度も何度も試行錯誤を重ねられたのだと思います。ビルドクオリティが非常に高いです。

Breitling AerospaceとApple Watch SE3を組み合わせて使っていますが、見栄えも良いです。便利なだけでなく、所有欲も満たしてくれる、本当に素晴らしいプロダクトです。

Fantastic work by the Smartlet team—this is an impressive product!!
