Smartlet Collections

Q: What is the difference between Smartlet One and the accessories?

Smartlet One is the original, in hand-brushed steel, matte black or titanium. Accessories extend it with connectors, straps and clasps. The patented connection is the same everywhere.

Q: Which collection should I start with?

Start with Smartlet One in the finish that matches your watches. Add accessories to cover more watches and devices.

Q: Do all collections use the same connection?

Yes. One patented connection carries every collection, so connectors, adapters and straps move freely between them.

Q: Where do I check if my watch is compatible?

The compatibility pages list more than 100 mechanical watch brands and over 20 smartwatches, by lug width from 18 to 24mm.

One connection. Every collection.

The patented Smartlet connection carries a mechanical watch and a smartwatch on the same wrist. Choose the collection that matches the watches you own.

The mechanism

How it works

Every Smartlet holds a mechanical watch and a smartwatch on the same wrist through one patented connection. Fit it once, then switch watches by hand in seconds. The connection is identical across every collection, so parts and straps move freely between them.

Our clients love Smartlet

Smartlet gave me the opportunity to enjoy my beloved timepieces, while monitoring my heart condition with my Apple watch. The product exceeds my expectations.

As an airline pilot, I am always on the run. Smartlet gives me the ability to wander across the world with my mechanical watches, while enjoying the benefits of technology. I am a fan.

First, I want to applaud the team for taking what appears to be a simple idea and realizing it at such a high level. Smartlet was worth the wait, and perhaps precisely because we waited, the product reached such an impressive level of refinement.

I am highly satisfied with the performance and design. I honestly expected greater restriction or discomfort given its function, but the daily wear has been surprisingly smooth. Furthermore, the look and finish of the strap itself are excellent.
