Smartlet One Classic

Images nouveau site - 169.png

For modern Gentleman

 Confident without arrogance, refined without excess.

Effortless Elegance

 

Smartlet One Classic is made for those who seek balance: a morning coffee in the city, an afternoon meeting, a weekend with friends. Elegant without effort, it combines comfort and versatility.

 

Designed to reflect light as naturally as it reflects your style, it adapts to your rhythm without forcing a choice between tradition and innovation. Your watch remains at the center, technology works discreetly in the background.

 

Subtle yet assured, Smartlet One Classic expresses the essentials: confidence, timelessness, natural ease.
