Made by hand in Czechia · Muonionalusta meteorite dials
Four and a half billion years. On your wrist.
Every Rivus dial is a slice of the Muonionalusta iron meteorite, as old as the solar system. Etching reveals a crystal pattern that never repeats, so no two dials are alike.
The Essence and Minimalist collections
Choose your watch
Essence has hour indices, Minimalist lets the meteorite speak without them. A 37 mm case, a Swiss automatic movement and a dial no one else has.
The dial fell from the sky
About a million years ago, an iron meteorite fell in what is now northern Sweden. Inside are nickel-iron crystals that grew over millions of years as the core of a small planet slowly cooled. Etched with acid, they form Widmanstätten patterns, a structure that cannot be made on Earth.
Each dial is cut from this meteorite in the Czech Republic. Every slice shows a different part of the crystal, so every Rivus dial is one of a kind.
Widmanstätten patterns · MuonionalustaSmall Czech workshops. One watchmaker.
A Rivus watch is the work of a few people who are each very good at one thing. A small engineering workshop in the Czech Republic makes the case to our own design. The meteorite dial is made in the Czech Republic too, and a saddler from northern Moravia stitches the leather strap by hand.
Our watchmaker, Tomáš Potoček, then assembles every watch by hand around a Swiss Sellita SW200 automatic movement and checks it before it leaves. The assembly alone takes about four hours; most of the time goes into everything before it.
“I wanted a watch that would be the most beautiful in the world, at least to me. Then a few friends wanted one too.”
What you get

A watch made for one person
Different indices, another strap colour, a detail that means something to you? Tell us what you have in mind. We will talk it through, give you the price up front and make the watch once you approve the design.
Authenticity you can check
Every dial comes with a certificate of authenticity from the Museum of Meteorites, a member of the International Meteorite Collectors Association (IMCA). It confirms that your dial is cut from genuine Muonionalusta.
