Do you want to buy a luxury watch, but not from a jeweler? Chronext offers a marketplace for luxury watches with a guarantee of authenticity.


High-quality sneakers made in Italy are the USP of Koio, a German startup. The founders thus occupy a niche in luxury shoes. 


Table water as a luxury product is a business idea. The “Premium Tafelwassser Cuvée” comes from two sources and shines with its noble presentation.

Luxury second hand

Second-hand is now also available in the higher price segment – online. Plagiarism and fear of fraud? Not at REBELLE.
